55 Best Science Experiments for High School Labs and Science Fairs
Fire up the Bunsen burners!
The cool thing about high school science experiments and projects is that kids are old enough to tackle some pretty amazing concepts. Some science experiments for high school are just advanced versions of simpler projects they did when they were younger, with detailed calculations or fewer instructions. Other projects involve fire, chemicals, or other materials they couldn’t use before.
Many of these science experiments for high school are intended for classroom labs, but most can be adapted to become science fair projects too. Just consider variables that you can change up, like materials or other parameters. That changes a classroom lab into a true scientific method experiment!
(Just a heads up, WeAreTeachers may collect a share of sales from the links on this page. We only recommend items our team loves!)

Awesome Science Fair Projects for Kids
March 9, 2019 By Emma Vanstone 4 Comments
Here at Science Sparks we LOVE a good science fair project but appreciate that not everyone feels the same way, so here are a few amazing ( and easy ) science fair project ideas to give you some inspiration.
Science Fair Top Tips
Let your child choose a science project that interests them, I find my children are much happier to get stuck into a project that they have chosen rather than something I think they should do. Obviously if they choose something too difficult you might have suggest something a little easier. A good starting point is to narrow it down to a selection of five you think would work for both of you and allow the child to make the final decision.
If you have a child who thinks they don’t like science and just isn’t enthusiastic, try to combine science with something they do love. For example, there are lots of brilliant art and science projects around. Or if you have a child who likes to build things, try one of our engineering projects . Books and stories can be a great source of inspiration too. We’ve got lots of story themed science activities for inspiration.
Try not to take over. I am terrible for interfering too much, but I’m really trying to take a step back and be the helper rather than the leader.
Messy Science Fair Projects

Find out why slimy has the properties that make it fun with a slime investigation using our easy slime recipe .
How can I make clear slime?
Make a batch of slime using opaque glue and one with transparent glue and compare the two. Slime made using soluble fibre is another variation you could try.
Can I make slime without glue?
YES! This slime recipe using Guar Gum looks great!
We have three borax and glue free slime recipes you could try too.
What’s the science behind slime?
Glue flows because the polymer chains slide over each other. When you make slime with glue and saline solution ( which contains boric acid ) the boric acid in the saline solution reacts with baking soda to form borate ions which form bonds between the polymer chains of the glue. This is called cross linking and is what makes the slime mixture stick together, making it slimy!!
Make a soda dispenser
This AWESOME soda dispenser idea is from from Steve Spangler and uses the good old mento and soda trick where you drop a mento into a bottle of coke and watch it fizz. You could use the activity to investigate how different types of sodas have different levels of reaction, and challenge yourself to see how many cups you can fill.
If you’d rather a less messy DIY drinks dispenser , we have a version that uses air pressure to dispense the drink and can be used over and over again.
Erupt a volcano with baking soda and vinegar
Learn about chemical reactions with a baking soda volcano . Experiment to find the perfect combination of vinegar, baking soda and washing up liquid ( dish soap ) to make the most realistic looking lava. Does thicker lava flow more slowly?
You could make a volcano from papier mache, modroc , sand or snow! Try making different colours, sizes and shapes.
Babble Dabble Do has an amazing lemon volcano that we bet will smell amazing too!
Red Ted Art has a brilliant erupting papier mache volcano too!
Weather Science Fair Projects
Track changes to the weather over a period of time by making a barometer to measure air pressure, a rain gauge to measure rain, a pinecone weather station and other fun weather science activities.
Weather based investigations are great if you have a period of weeks or months to track changes and a perfect for learning to record and display data. We love weather science!
Food Science Fair Projects
Why does fresh pineapple stop jelly setting.
Try some kitchen science and investigate why fresh pineapple stops jelly setting . You might find some other fruits have the same effect…
Edible Life Cycles
Create a series of edible life cycles. This butterfly life cycle is a great example to get you started.
Investigate tooth decay with egg shells
Egg shells are the perfect material for investigating the effect of different substances on teeth . Coffee, vinegar and fizzy drinks are great things to try first.
Density Science Fair Projects
A density jar makes for a wonderfully visual science demonstration. See how many layers you can float on to of each other and try to find an object to float on each layer.
You could even try a little science magic trick. Although this can get messy so be careful.
Osmosis Projects for a Science Fair
Osmosis always sounds like a really tricky subject, but actually it’s pretty simple. You can use eggs with no shell to demonstrate easily.
Use eggs to investigate osmosis and diffusion .This simple, low cost activity is great for explaining quite complex processes and very visual as well.
The photo below shows how water has moved into one egg ( with the shell removed ) and out of the other.
Make a Scribble Bot
A Scribble or Art Bot is a fantastic creative science fair project. Try changing the position of the pens and size of spinner to change the effect.

100 Easy Science Experiments for Kids to do at Home (2023)
Do you have a budding scientist living in the house with you?
You’re probably looking for hands-on science experiments for kids that you can do at home.
The only problem? So many experiments require obscure ingredients that are hard to find or require planning.
Here’s the good news.
There are literally hundreds of simple science experiments & STEM activities you can do at home, with materials you already have on hand.
(Yes, you read that right.)
We scoured the internet and practiced these experiments with our own young kids to test them out and make sure they were good ones. They’re super educational and so much fun for kids of all ages!
Each of these easy STEM challenges and science experiments will take about 30 minutes to complete from start to finish.
The best part?
They each use simple ingredients from around the house like food coloring, dish soap, paper towels, ice cubes, rubber bands, white vinegar, vegetable oil, and baking soda.
And, they teach simple science concepts that your kids will use in school for years to come.
It’s also a great way to learn about the scientific method that they’ll use throughout their schooling and perhaps their whole life.
How can you beat that?
Even better, one simple experiment might be the light bulb moment that inspires them to be a scientist for life.
(At the very least, you’ll probably inspire some really cool science fair projects.)
So, let’s dive in!
Here is our massive list of fun science experiments to introduce your child to the magical world of science.
100 Easy Science Experiments for Kids to do at Home
1. homemade lava lamp.
This simple lava lamp experiment is especially a hit with kids ages 4-12 (and beyond!), and it will take their favorite adults back a few decades, too!
This easy science activity teaches kids about density, and uses common ingredients from around the house.
What You Need:
A clean plastic bottle (or several plastic bottles) Water Vegetable Oil Fizzing tablets (like an Alka-Seltzer tablet) Food Coloring
Fill the bottle up with water about 1/4th full. Pour the vegetable oil into the bottle until is almost full. Use a funnel if you have one. Wait a few moments and watch as the oil and water separates.
Then, add a few drops of your favorite color food coloring. Watch the color make its way through the oil.
The next step is to break your fizzy tablet in half and drop part of it into the bottle. Watch the bubble blobs form.
Finally, if you have a flashlight, turn off the lights and drop in another half tablet. Shine the flashlight through the lava lamp while the blobs are bubbling!
What’s Happening:
The oil floats on top of the water because it is less dense (lighter) than water. The food coloring has the same density as the water so it sinks through the oil and mixes with the water. As the tablet dissolves it creates a gas called carbon dioxide.
Gas is lighter than water so it floats to the top, bringing some color with it from the food coloring. When the air releases from the colored water blob, the water gets heavy again and sinks.
2. Exploring Surface Tension (With Black Pepper!)
S urface tension is a foundational scientific principle that even young kids can begin to learn about. This simple experience using water, soap, and black pepper will get kids of all ages exploring this useful concept.
black pepper a plate or bowl water liquid soap
First, fill the plate with a thin layer of water, less than an inch deep is plenty.
Then, sprinkle the pepper on to the water, covering a much of the water surface as possible. The more pepper, the more fun.
Finally, dip your finger into the liquid soap. Touch the pepper and see what happens!
The soap is breaking the surface tension of the water! Surface tension exists in water because the water molecules (the littles pieces of the water) like to stick together.
Water has high surface tension, which mans the molecules like the pull towards each other and stick together very strongly.
But, when soap is added to it, it break the surface tension. The molecules close to your fingers are pulled away by molecules that are farther away from your finger.
3. Elephant Toothpaste
H ave you heard of the elephant toothpaste experiment yet? It’s a blast! You will need an adult for this experiment. Kids of all ages will love learning about catalysts and exothermic reactions in this simple fun science activity.
16-oz plastic soda bottle
1/2 cup 20-volume of 6% solution hydrogen peroxide liquid
1 Tablespoon dry yeast
3 Tablespoons of warm water
Liquid dish soap
Food coloring
Safety goggles
First and foremost, put on your safety goggles or protective eyewear. Hydrogen peroxide can irritate skin and eyes. As a safety precaution, an adult should always be the one to carefully pour the hydrogen peroxide into the bottle.
The next step is to add 8 drops of your favorite color food coloring into the bottle.
Then, add 1 tablespoon of liquid dish soap and swish the bottle around the mix the ingredients together.
In a separate cup, mix the warm water and yeast together for 30 seconds.
Finally, pour the yeast water mixture into the bottle and watch the foam form!
Each tiny bubble in the foal is filled with oxygen. The yeast was a catalyst (it helper) to remove the oxygen from the hydrogen peroxide. Because it happened so fast, it created lots of bubbles.
The bottle got hot because this reaction is an exothermic reaction that created heat. The foam is made up simple of water, soap, and oxygen, so you can safely pour it down the drain. Voila!
4. Homemade Slime
What kid doesn’t love slime? This is one of our favorite science experiments because it’s a sure kid-pleaser! In this basic recipe, you can make some of your own right in your kitchen, and have fun squeezing it with your bare hands all day long. Slime has quickly become one of those classic science experiments that every family should try at least once!
Water White school glue food coloring borax two bowls
First, mix 1/4 cup of water and 1/4 cup of white school glue in a bowl. (Double the recipe if you’d like more.)
Next, if you want your slime to be colorful, add a few drop of food coloring to the mixture.
Then, mix 1/2 tablespoon of borax and 1/2 a cup of water and stir it around until the borax dissolves. I
Finally, add the borax solution to the glue mixture and mix them together. Voila!
Variations:
For glow in the dark slime, use glow-in-the-dark glue. For glittery slime, add glitter!
Don’t have borax lying around the house? Order some from Amazon at a good price.
5. Light Refraction Magic
This super simple science experiment is really more of a magic trick, and it will teach your kids all about light refraction.
Piece of Paper
Get a sheet of paper and draw two big arrow on it, one near the top, and one new the bottom. Make the arrow point in the same direction.
Next, fill a glass with water. Slowly lower the piece of paper behind the glass of water. Look through the glass of water, and watch in amazement!
Refraction is the bending of light and it happens when light travels from one medium to another, like from air to water, or water to air. In this experiment, the light traveling from the paper through the air, then through the glass and into the water, and finally out of the glass and into the air one more before ever reaching our eyes.
Light travels the fastest through air, and a little more slowly through water, and even MORE slowly through glass. That means that the light bends when it travels through the glass cup into the water, and then it bends again when it travels out of the glass cup into the air.
The light paths actually cross and the image appears to be flipped.
6. Dancing Raisins
Home science experiments don’t have to be complicated. In this very easy science experiment that’s perfect for young kids, you’ll need a few simple ingredients that you probably already have in your household: clear soda, a glass of water, and a handful of raisins. With these simple ingredients, you’ll produce chemical reactions that your kids can watch in real time!
What You’ll Need:
A clear glass of water
Handful of raisins
First, you fill one glass with clear soda, and another glass with plain water or a different liquid that does not have gas bubbles. Then, place the raisins in each glass, and watch how they dance in the glass with clear soda.
The gas bubbles from the soda carry the raisins upwards. When they pop, the raisin sinks again.
What’s happening?
Once the carbon dioxide bubbles reach the surface of the soda they pop and the gas is released into the air. This makes the raisin lose buoyancy and fall back down to the bottom of the glass. This is why the raising acts differently in different liquids.
7. Sink or Float?
Kids of all ages but especially young children will love this easy science experiment that builds a foundation to understanding density. This is one of our favorite science activities for the little ones!
Two glasses of water
Small items from around the house
A piece of paper and a pen
First, you fill two large clear containers with water. Then, ask your kids to gather small items from around the house in order to see if they’ll sink or float.
Before you test them, have you kids write a list of the objects on a piece of paper and ask them to predict if they’ll sink or float.
Now, test out each item, and compare it with their hypothesis! This is a great way to teach them the scientific method.
Finally, you can ask them, now that they have seen some of the objects sinking and floating, is there anything else they’d like to test?
8. Shiny Pennies
You definitely have some dirty pennies lying around your house, so let’s put them to good use in a simple and fun science experiment that even young kids can enjoy. Pennies are copper, and they are often in circulation for years (yuck!), so they often appear very tarnished. In this experience, you’re going to see if soap or vinegar (or other liquids) do a better job at cleaning the exterior of the dirty copper penny.
What You’ll Need
dirty pennies
2 paper cups
Paper towel
Other liquids from around the house (ketchup, soda, etc.)
First, make some guesses about which liquid will make the penny the shiniest.
Then, put each penny in a paper cup. In one up, pour in enough vinegar to totally cover the dirty penny. In the other cup, pour in enough dish soap to totally cover the dirty penny.
Wait about ten minutes. A
fter ten minutes, take the pennies out, rinse them in water, and rub them with a paper tower. Now compare the pennies and see how clean they got!
Lastly, try it with other liquids from around the house.
Pennies get dull over time because the copper on the exterior reacts with oxygen from the air. The copper and oxygen form copper oxides that make the penny dull and dark.
The acetic acide in the vinegar dissolves these chemicals and leaves the penny looking new and shiny.
Dish soap is great for cleaning lots of things, but it can’t dissolve copper oxides.
9. Rainbow Celery (Capillary Action!)
Got some celery in the fridge? Then you can begin to l earn about capillary action with a simple and colorful color-changing celery experiment. It’s a really cool project that your kids are sure to remember for years to come!
What you need:
Glasses of water
Find a sunny spot, and fill the glasses up halfway with water.
Then drop different colors of food coloring into each of the glasses. (It’s fun to put the colors in the order of a rainbow!)
Next, cut stalks of celery and put them in the glasses of water.
Let the celery sit for awhile. It will take a few hours at least, but pretty soon you’ll notice the leaves changing colors. You can also do this experiment with a light-colored flower.
This easy experiment will demonstrate to your child how the small “vessels” in celery stalks can carry the water (and rainbow colors!) to the leaves of the celery, mimicking the way blood travels through the body.
10. Mixing Impossible
This super easy experiment involves mixing equal parts oil and water and adding a drop of food coloring to see what happens. Kids will love watching the food coloring make it through the oil. You will love how easy it is to set up and clean up!
Several drinking glasses
vegetable oil
liquid food coloring
a toothpick (if you have it
First, ask yourselves what you think will happen when you mix oil and water together.
Then, pour about ½ cup of oil into a drinking glass
Next, pour the same amount of water into the same glass
Watch how the two separate from each other!
Ask what they think will happen when you put one drop of water-based food coloring into the oil
Have the child put a drop in and observe (if the drop needs encouragement to move downward, use a toothpick)
Ask again which is denser, the water-based drop or oil (the water-based drop sinks, showing it’s more dense than oil)
Imagine two objects that are the same size but different weights. The one that weighs more has more matter packed into it. It is denser. A good way to tell if something is more or less dense than water is to put it in water. If it sinks, it’s denser, if it floats, it’s less dense. The oil floats, showing it’s less dense than water.
11. Exploring Colors With Baking Soda / Vinegar
I n this science activity for kids of all ages, your little scientists will create a chemical reaction, explore color mixing, AND create colorful artwork. Triple win!
Tray (A baking sheet will do)
Baking soda
White vinegar
Ice Cube Trays or other containers to hold the colored vinegar
Pipettes or eye droppers
Liquid watercolors or food coloring
1. Give each child a tray.
2. Fill the tray with a heaping amount of baking soda.
3. Fill each ice cube tray (or other container) with vinegar. Add liquid watercolors to the vinegar so your child has a variety of colors to use.
4. Use a pipette or eye dropper to place a few drops of the colored vinegar onto the tray of baking soda. Watch what happens!
5. Continue exploring with other colors.
One reader said this kept her kids busy for an hour! Priceless.
12. Tie-Dye
Who would have thought that everyone’s favorite t-shirt pattern is actually a great science lesson, too? All you need is an old white t-shirt or pillowcase, some rubber bands, buckets, and dye.
Next, roll up your t-shirt and tie each rubber band strategically to create a design.
Then, begin dipping the t-shirt in the different colored dyes.
As your child dyes the shirt, they’ll be observing water solubility and absorption in real time. The dyes are fiber-reactive, which means that a chemical reaction takes places between the dye molecules and fabric molecules so that they actually become one. The dye bonds with the fabric and actually becomes a part of it.

13. Mini Volcanos
This super easy baking soda and vinegar volcano eruption is a real crowd-pleaser for kids of all ages, and your kids will be begging to do it over and over again!
All you need is a few very basic household ingredients, and your colorful volcano will be erupting in no time. It only takes about three minutes to prep.
If you want this to be a no mess science experiment, plan to do it outside on the dirt or on rocks.
Ingredients
Plastic cup
3-4 Tbs of baking soda at least
1 tsp of dish soap
Food coloring (or washable paint if you want to avoid staining)
1 cup (8 oz) of Vinegar
First, combine your base ingredients by putting the water inside of the plastic cup and filling it about 2/3 full.
Then add the baking soda, dish soap, and a little bit of food coloring or washable paint. Using washable paint instead of food coloring will help you avoid staining.
Stir the ingredients together.
Then, pour in the vinegar until it starts foaming and pouring out of the cup.
Repeat as necessary with more colors. Your kids will definitely be asking for more.
The “lava” bubbles that erupt are filled with carbon dioxide. The carbon dioxide is a gas that forms when an acid — the vinegar — reacts with a base — the baking soda.
14. Static Electricity Hair
Want to provide your kids with (literally) hair-raising good time? It’s super simple to teach your kids about static electricity with this easy, no-mess science activity.
What You need:
an inflated balloon
a piece of cloth
Rub the surface of the balloon with the cloth for at least40 seconds. Then, hold the balloon a short distance above your head and watch your hair stick to it!
T he balloon gains electrons from the cloth and becomes negatively-charged when you rub it together. Then, when the balloon touches you hair, it attracts your hair, which is positively charged.
15. What’s That Mystery Smell?
Kids of all ages can recognize a lot of different smells, and the process of using your senses is very important to the scientific method.
In this experiment, you’ll use your senses to see how many different smells you can recognize.
A grown-up or friend to help
A blindfold
Small, lidded containers that you can’t see through
Smelly things from around the house such as bananas, an orange peel, lemons, a cotton ball soaked in perfume, chopped onion, coffee (or a used coffee filter!), rose or flower petals, pencil shavings, vanilla, vinegar, ginger, etc.
First, have a grown up put the smelly items in the containers.
Then, write a number on the side of each container.
The next step is to put your blindfold on and have them help you smell each object.
Write down what you think is inside of each container.
Finally, check your guesses! How many did you guess correctly?
16. Water Cycle In A Bag
This is one of the best science experiments to teach your kids about the water cycle, and it’s so easy to do!
-Zip lock bag
-permanent marker
-blue food coloring
-clear tape
First, use a permanent market to draw a sky on the upper half of your ziplock bag. Include clouds and the sun.
Next, fill a cup with water and add a few drops of blue food coloring. This will help the water be more visible to your kids. Mix it up until it’s a striking blue color.
Then, pour the water into the bag and zip it tight so no water escapes.
Now, hang your bag up on a window that gets a lot of sunshine. Affix it with tape on the corner to ensure it doesn’t fall.
In a couple of hours, you can check on your bag, and then check again in about a day. You will eventually start to see drops of water sticking to the side of the bag. Some will be in the “clouds” and other drops will be coming down like rain.
What’s Happening?
The sun is heating up the water in the bag, which turns the water into a gaseous state in a process called evaporation. This happens in our atmosphere, too. Because the water is in a bag and has nowhere to go, it sticks to the sides of the bag, turning back into a liquid. This is called condensation. This experiment demonstrates the power of the sun to transform water into different states.
17. What’s That Mystery Object?
The process of using your sense of touch is very important to the scientific method. In this experiment, you’ll use your sense of touch to see how many different textures you can recognize.
A “feely” bag that you can’t see through
Small objects from around the house that have different textures, such as: a plastic bag, a water bottle, a banana, a piece of paper, a cell phone, a rubber ball, a cotton ball, a tooth brush, a washcloth, etc. Try to find objects of different materials like velvet, wool, cotton, leather, metal objects, wooden spoons or toys, pieces of aluminum foil, and other interesting objects and textures.
First, put on your blindfold. The next step is to have a grown up or friend put a mystery object in the bag for you to fell. Can you guess what each object is?
18. Sugar Water Rainbows
This science experiment is especially meant for older kids, but it can me modified for kids of all ages. Your kids will love this colorful experience about density and buoyancy, and all you need are some common household ingredients.
food colorings (preferably in rainbow colors including red, orange, yellow, green, blue, purple)
a clear straw
First, fill each of the cups with the same amount of water.
Next, add the food coloring, one color in each cup, preferably in rainbow order.
Line the cups up next to each other.
In the first cup, do not add any sugar at all.
In the second cup, add one tablespoon of sugar.
In the third cup, add two tablespoon of sugar.
In the fourth cup, add three tablepoons of sugar, and so on.
Stir each mixture until all the sugar is dissolved in each glass.
The next step is to make a sugar rainbow by placing the end of the straw in the first cup (the cup with no sugar), only about a half of an inch.
Cover the top of the straw with your thumb before lifting it out of the water so that the water does not fall out of the straw.
Now dip the straw into the second cup (1 tablespoon sugar). This time, insert it deeper so that the end is one inch below the water level. In one quick move, release the thumb and recap again. Now you should have two layers of color.
Keep dipping the straw into each solution from the one with the least sugar to the one with five tablespoons of sugar. Each time, the straw is inserted half an inch deeper.
Density is the amount of substance (mass) within the volume occupied by the object. If two cups have the same amount of water (i.e. same volume), the one with more sugar is denser than the one with less sugar.
Buoyancy is determined by relative density. The solution with less density floats above the solution with higher density. That is why the color don’t mix.
Sugary water has higher density than plain water. The solution with more sugar has higher density than the one with less sugar. If you have inserted the straw in the solutions from the least sugar to the most sugar, then the color don’t mix and you have a sugar water rainbow.
19. Painted Nature
In this activity, kids will be closely observing natural phenomena, looking for signs of life and growth, and using their senses to experience natural materials. These skills are extremely important scientific foundations.
First, have your child search for natural objects in nature. Fill a bag with interesting sticks, leaves, rocks, twigs, pebbles, and anything else you can find.
Next, bring them into the “classroom” or home to closely observe and paint them.
As you paint, you can discuss the natural colors and features of these objects: What is their texture? What do they notice about each object?
20. Magnet Dump
This activity is a great introductory magnet activity, and for younger kids, they’ll be practicing skills of classifying and sorting.
First, dump out a selection of metal objects onto the table.
Next, ask your kids to help you “clean up” by using the magnets to pick up different objects and sort them into containers.
Discuss which objects are attracted to a magnet and which are not. What patterns do they notice? What other objects would they like to try?
21. Magnet Magic
-Clear plastic box (look in your recycling bin)
-Pipe cleaners
This super-easy experiment is a really fun way to teach your child about magnets in a colorful, magical way, and it only requires simple materials from around the house.
First, cut up several pipe cleaners and place them in a clear plastic box. The box does not need to be fancy, just see-through.
For your first time through this demonstration, have your child take a magnet and touch it against the surface of the plastic box. They’ll find that the pipe cleaners are lifted up and move with the magnet!
Magnets attract certain types of metal. The pipe cleaners have a thin strip of metal, so the magnet is able to attract those pieces and pull it around the box.
Extension: Next time, think of what other objects could you place in the box? What objects do you predict the magnet could move around?
22. Will it melt?
In this experiment, your kids will learn about heat and how it affects every day objects.
The main question is “Will it melt”? And the best way to find it is to try!
First, gather a range of materials (within reason) and put them in a muffin tin.
Discuss with your kids about how temperatures can get high, especially on hot days.
Ask your kids to hypothesize about what will and won’t melt.
Then put it to the test!
Caution! Be extremely careful about what you put in the muffin tin so that you do not start a fire or ruin your pan.
23. Traveling Rainbows
This colorful experiment is an easy way of demonstrating capillary action, water travel, and color mixing.
Kids of all ages will love watching the color move through the paper towel on its own, and they’ll have a better idea of how plants get their nutrients.
6 glasses or jars
Paper towels
Food coloring (red, yellow, & blue)
First, fold six sheets of paper towel lengthwise. You may need to cut a few inches off so that it fits into the glasses well. They should go from the bottom of one mason jar to the next without sticking up too high in the air.
Next, fill the first glass with a generous squirt of red food coloring, the third with yellow, and the fifth with blue. Mix it up with a plastic spoon. Leave the other glasses empty.
Then, add water to the glasses with color until the colored water almost reaches the top.
Now add the paper towels. Starting with red, add once end of the paper towel and put the other end in the empty glass next to it.
After several minutes, the colored water will travel almost the whole length of each paper towel. You can watch the water do its magic for about 20 minutes!
The colored water travels up the paper towel by a process called capillary action. Capillary action is the ability of a liquid to flow upward, against gravity, in narrow spaces. This is the same thing that helps water climb from a plant’s roots to the leaves in the tree tops.
Paper towels (and all paper products) are made from fibers found in plants called cellulose. In this demonstration, the water flowed upwards through the tiny gaps between the cellulose fibers. The gaps in the towel acted like capillary tubes, pulling the water upwards.
The water is able to defy gravity as it travels upward due to the attractive forces between the water and the cellulose fibers. The water molecules tend to cling to the cellulose fibers in the paper towel. This is called adhesion. The water molecules are also attracted to each other and stick close together, a process called cohesion. So, as the water slowly moves up the tiny gaps in the paper towel fibers, the cohesive forces help to draw more water upwards.
24. LEGO Boats
This experiements present a great opportunity to get kids thinking about engineering and design.
First, challenge your kids to build their own boat out of LEGO bricks. For an added challenge, only give them a certain number of pieces.
Once everyone has finished building, put the boats to the test in a tub of water.
Add pennies a few at a time to see how many each boat can hold.
Talk to your kids about how weight and design matter. Reflect on good designs and help them understand why they worked well.
25. DIY Parachute
You can learn about gravity by making a DIY parachute for a light-weight toy. The parachute is easily made from materials around your house, and you can experiment with different strategies and objects.
Plastic Bag (i.e. grocery bag)
Yard/String
First, use the scissors to remove the handles from the plastic bag. Next, poke four holes around the plastic bag so that they are the same distance apart and on opposite sides of the bags.
Then, cut four holes into the rim of the paper cut.
You’ll also need to cut four pieces of yarn, 10-12 inches long. Thread one piece of yarn through the hole in the plastic cup and tie the yarn to the cup with a knot. Repeat with all four strands of yarn in the remaining holes.
Next, thread the other end of the pieces of yarn through the hole in the plastic bag and tie a knot.
Finally, personalize and decorate your cup with stickers, paint, crayons or markers.
Now it’s time to find a toy that is going to take a ride in your parachute. Launch your parachute into the air and see what happens!
Experiment with putting different objects into the paper cup and see how it affects the parachute’s effectiveness. Does the parachute flight time increase or decrease?
You can also try creating the parachute with different materials to replace the paper bag, such as a paper towel or napkin, and see how that affects the performance.
26. Magic Milk Experiment
-Full Fall Milk
-Food Coloring
-Dawn Dish Soap
-Cotton Swabs
First, pour the milk in a small baking dish until the bottom is covered. Next, fill the milk with drops of food coloring. Glitter is optional!
Then, pour some dishwashing soap into a bowl, and dip your cotton swap tip into the dish soap to coat it. Then, gently touch your cotton swab to the milk and watch what happens!
Milk is composed of minerals, proteins, and fats, which are easy to change. When you add the dish soap to the milk, the soap molecules try to attach to the fat molecules in the milk.
When everything stops moving, you can see where all the fat molecules are.
27. Steel Wool & Vinegar Reaction
This experiment will make abstract concepts like “chemical reaction” and “rusting” become more clear and concrete.
-steel wool
-two beakers
-something to cover the beaker (paper or a lid)
-Thermometer
First, place the steel wool in a beaker. Then, pour vinegar onto the steel wool and let it soak for about a minute.
After a minute or so, take the steel wool out and shake off any excess vinegar.
Next, wrap the steel wool around the base of the thermometer and then place them both in the other beaker.
Then, cover the beaker with paper or a lid. It’s important that you keep the heat in.
You’ll want to make sure that you can still read the temperature on the thermometer. It’s a great idea to poke a hole if possible through the covering so that the thermometer can fit through it, and you can easily read the temperature.
Make a note of the initial temperature, and observe it for about five minutes.
You will see that the temperature on the thermometer gradually rises, and the beaker will likely get foggy. When you soaked the steel wool in vinegar, it removed the protective coating on the steel wool, allowing the iron in the steel to rust.
Rusting is actually a chemical reaction between iron and oxygen (or oxidation). This is the chemical reaction that creates heat, thereby increasing the temperature of the beaker and on the thermometer. This is an examples of an exothermic reaction (a chemical reaction that releases energy in the form of heat).
28. Invisible Ink
In this fun experiment, your kids can write secret messages that they will learn how to reveal scientifically. You need only basic materials, and it’s sure to be a big hit.
-Cotton swab
-lamp or light bulm
-plain white paper
-bowl or cup
-lemon juice
First, squeeze the lemon juice into a bowl or cup and mix in a few drops of water.
Next, dip the cotton swap into the lemon juice / water mixture, and write a secret message or draw a secret picture onto the plain white paper.
Wait a few moments for the paper to dry and for the juice to become invisible.
Finally, hold the paper close to a light bulb or lamp and reveal your secret messages.
Lemon juice contains carbon compounds that are colourless at room temperature. The heat source (in this case the light bulb) breaks down the compounds and thereby releases the carbon. The carbon oxidizes when it comes into contact with the air. It then turns brown, making your invisible message visible under the hot light bulb.
29. Corn Syrup Viscosity Experiment
This experiment could not be simpler, and it’s the perfect tool for teaching kids of any age about viscosity.
-Corn Syrup
-2 glass containers (one should be smaller than the other)
-cupcake pan or 3 small bowls
-Food coloring
First, fill the larger glass container 1/2 to 3/4 full with corn syrup. Then, add the small glass container to the center. Careful! The corn syrup will rise a bit when you do this.
Next, Use a cupcake pan or 3 small bowls and put in a small amount of corn syrup. Mix each one with a food coloring of your choice. You should have three separate colors of corn syrup.
Then, put some colored corn syrup in the dropper, insert the dropper into the clear corn syrup and add the coloring in different places. Do that for each color as many times as you wish.
Now, you can turn the smaller glass jar while holding the outer glass still. The colored syrup will start to spread a bit. Now, switch direction and turn the small glass jar back to its original place. The colored dots return right back to their original form.
Corn syrup has a viscosity that is 5,000 times that of water, so they don’t mix in the same way.
30. Orange Fizz
This sensory experiments is really fun for learning about acids and bases. And hardly any materials are needed!
Orange or clementine
1/2 teaspoon baking soda
First, separate the orange into sections. Then, dip a slice into the baking soda. Finally, take a bite. It will start to bubble in your mouth!
The citric acid from the orange and the opposite base from the baking soda are mixing together, creating carbon dioxide bubbles.
31. Dry Erase Magic
Overview: In this fun and easy experiements, you’ll watch your very own drawing come to life and move around!
Glass Plate
Dry Erase Marker
First, draw a picture on the plate with the dry erase marker. Try a stick figure to start!
Then, slowly pour water onto the plate. You’ll see the drawing slowly lift up.
Finally, make your drawing move around by swirling around the water.
The marker is a mixture of ink pigments and alcohol. When you pour the water on it, the alcohol dissolves, and the ink pigments become a solid that slides off the glass when it gets wet.
32. Homemade Play Dough
This is a classic DIY project, and kids of all ages will love it.
-3 cups of flour
-1.5 cups of salt
-6 teaspoons cream of tartar
-3 tablespoons of oil
-3 cups of water
33. Melting Snowballs
This is another acid and base experiment, and it’s fun on a couple different levels!
-Baking Soda
First, form snowballs by adding water to the baking soda. You’ll need about a 1/3 cup per snowball.
Then, place them in the freezer for 15 minutes.
Finally, pour drop of vinegar on the snowballs and watch them sizzle and melt.
You can also make a snowman and do the same thing!
34. Exploding Soap
This is a surefire hit, and all you need is soap and microwave!
-Ivory Soap
First, put the bar of soap in a microwave safe bowl. Then, heat it up on high power for two minutes. Enjoy the show as the soap grow! Finally wait a couple of minutes for the bowl and foam to cool before you touch it.
Ivory soap contains small air bubbles that expand when heated in the microwave. The soap is in a solid state, so when it expands, it stays in its expanded size for the most part.
35. Paper Airplanes
Overview: There’s no better way for kids to learn about aerodynamics than by making a paper airplane. Wow Fold, a paper airplane website, offers dozens of paper airplane designs and easy to follow instructions.
36. Flying Ping Pong
Your kids will love this flying ping pong trick, and there are only two things you need.
First, make sure your hair dryer is on a cool setting.Then, hold the ping pong above the nozzle and turn on the air. When you let the ping pong go, it should float! Next, try it on different settings. Try to see how far you can tilt your hair dryer before the ball drops.
37. Magical Balloon
Your kids won’t believe their eyes when you push a needle through a balloon and it doesn’t pop!
-Scotch tape
First, blow up your balloon. Next, take two pieces of scotch tape and make an X on your balloon. Then, with parental supervision, push a needle through the middle of your X.
Leave the needle in and see how long it take for your balloon to finally pop!
The tape slows down the process of the hole in the balloon widening, so it takes longer for the balloon to pop.
38. Wacky Spoon
This is more of a science trick than an experiment, but it’s super easy to do at home!
Kitchen Spoon
Look at your reflection in a large spoon. It will be upside down!
A regular mirror is flat and sends your reflection straight back into your eyes. The rounded spoon bounces your reflection back at different angles and turns your reflection upside down.
39. Floating Eggs
This experiment will show your child how things float differently in fresh water and salt water.
-2 tall drinking glasses
First, fill one glass with water. Then, fill another glass with water and add 8 tablespoons of salt. Mix it up.
Next, place an egg in both glasses. One will float and the other will sink.
Adding salt to the water increases the water’s density which causes the egg to float.
40. Jumping Pepper
This simple experiment will demonstrate static electricity right before your eyes.
Place a tablespoon of pepper on a plate. Then, run a hair comb through your hair. While still holding on the comb, hold the comb over the plate and watch the pepper jump!
The plastic comb builds up a negative charge as it moves through you hair. The pepper has a positive charge, so it jumps!
Try it with other spices and powders.
41. Walking on Eggs
Your kids will be astonished to see that they can actually walk on eggs without breaking them!
-6 dozen eggs in their cartons
-Drop cloth / newspaper
Lay down your drop cloth in case the experiment doesn’t work as expected!
Place the open egg cartons next to each other. Tkae off your sock and shoes and gently step onto the eggs keeping your feet flat. Then bring up your other foot and carefully walk across the eggs.
Your foot is big enough that your weight spreads evenly out across the eggs, keeping them from breaking.
You can also demonstrate this concept with a heavy book.
42. Disappearing Reflection
Make your reflection vanish! All you need is aluminum foil.
-Aluminum Foil
-Scissors (optional)
Rip off a large piece of aluminum foil (ten inches should do) and take a look at your reflection. Then, crumple up the aluminum foil. Next, Carefully flatten it back out. Finally, look for your reflection. It’s nowhere to be found!
When the aluminum foil is smooth, light reflect off of in in straight lines, which enables you to see your reflection. But once you crumple the foil, it has a wrinkled surface that sends your reflection in all different direction, causing it to disappear.
43. Defy Gravity!
When you turn over a cup of water, you expect the water to spill and fall. But not always!
Clear plastic cup
Playing card or notecard
First, fill your clear glass about 3/4 of the way with water.
Next press your playing card or notecard gently on the top of your glass to completely cover the top. Gently rotate the cup upside down. After a few moments, remove the card. The water will stay in place!
Try it again, adding something that will float in the water. Repeat the steps, and see what happens!
44. Skittle Heart
Overview: Especially around Valentine’s Day, this science experiment will be well loved by your kids.
Small bowl with a flat surface. (Like a small pie pan.)
Heart-shaped cookie cutter (or any shape)
Place your skittles around the outside of the bowl in an intentional pattern. Two red skittles, following by two purple skittles, etc works well. Then, place the heart cookie cutter in the center of the bowl. Slowly pour water into the cookie cutter and see how the colors from the skittles magically fill the bowl!
45. Water Fireworks
This totally safe fireworks experiment will be a hit around the Fourth of July or any time!
Tall water glass
Small water glass
First, fill up your all water glass almost all the way with water. In the small glass, pour two tablespoons of oil. Add 2 drops of food coloring to it and mix it around with a fork until the food coloring is broken up into smaller specks.
Then, pour the oil mixture into the water and see the firework expand!
What’s happening:
Food coloring dissolves in water but not oil, causing it to go different directions.
Try two colors! Try a different size glass!
46. Bird Feeder Fun
In this simple science project, you’ll learn where birds like to have their meals.
-Pipe Cleaner
Place cheerios on a pipe clean and make a simple circle. Place it out for the birds to eat.
To experiment, place different bird feeders in different places and see if it makes a difference for how much gets eaten.
You could also make your bird feeder into different shapes to see how the birds prefer it.
47. Rain Gauge
It’s super simple to make a rain gauge from a soda bottle and track your are’a rain water!
Soda Bottle
X-acto knife (with parental supervision)
Cut the top off of a soda bottle and invert the top so that the rain water funnels into the bottle. You may want to secure it with duct tape. Next, place it outside in a spot where it can collect rain water.You’ll want to secure it so it doesn’t fall over. Then, begin measuring the rain water each day!
48. Magic Leak Proof Bag
-Ziplock Back
-Very Sharp Pencils
Fill your bag up halfway with water. Carefully poke the pencil through the bag and out the other side. (Don’t push the pencil all the way through so that it comes out the other side!)
The plastic bag’s molecules form easily around the smooth sides of the pencil forming a seal.
49. Paper Cup Tower
Similar to the “walking on Egg” experiment listsed above, this activity will wow your children as they discover they won’t crush the paper cups by standing on them!
8 paper cups
First, set the paper cups on the grounds, spaced evenly. Next, place the cardboard on top of them. Then, try to stand on it and see what happens. Can you make another level?
50. Rubber Band Guitar
Tap into your musical side and explore sound with this simple rubber band guitar.
Paper or plastic cup
Rubber bands
First, wrap your rubber bands of different sizes around the cup so that the rubber bands act as strings over the hole of the cup. Then, pinch the sides of them together as best you can and tap them around the sides of the cup. See what sounds they make, and experiments with rubber bands of various sizes to see what sounds they make!

Liftoff: Science projects by students from 5 Florida schools headed to space
March 3, 2023 Education , Fresh Take Florida , Technology
OCALA, Fla. – What started out as a group project turned into one middle school student getting her science experiment a seat to the International Space Station, one of five such projects headed to space from schools across Florida.
Collins Sheldon, 11, proposed testing whether microgravity in space affects the production of E. coli proteins that can be made into medicines, possibly speeding up the manufacturing of pharmaceuticals.
The Student Spaceflight Experiment Program picks students’ experiments to launch into space with astronauts where they perform the experiments on the International Space Station to gather data for the students.
It selected only 39 proposals from the 2,261 submitted in December for this school year’s contest from across the world. Five came from schools across Florida – two from Hillsborough County and one each from Marion, Sarasota and Brevard counties.
Sheldon, a student at Howard Middle School, began her proposal last year as a fifth grader with a group of five other girls. Their project was not selected. When they graduated from elementary school, they were offered the chance to submit another proposal. The five other girls were too busy, so Collins decided to try it all on her own.
Collins said she shared news of her selection with friends: “They were all really excited,” she said.
The other four projects from Florida include:
- Two from the Randall Middle School in Lithia, near Tampa. They may help answer questions about how astronauts on long-duration flights can eat. One involves whether a particular plant, Red Garnet Amaranth, can grow in microgravity. The other explores the effects of microgravity on the nutrition and growth rates of sesame microgreens.
- An experiment from Pine View School for the Gifted in Osprey in Sarasota County will try to answer questions about whether a microbe, Chlorella vulgaris, can be used to remove nitrogen and phosphorus from wastewater in microgravity.
- An experiment from Pinecrest Space Coast Academy in Viera Beach will study how to detect toxins in microgravity using properties in horseshoe crab blood.
Realistic and hands-on experience is the point of the program, said Jeff Goldstine, the center director of the Maryland-based National Center for Earth and Space Science Education. He said members of the review board who choose the final experiments say they never did research proposals on this scale until graduate school.
“The only way to do that is to bring real-world experiences from the professional STEM into the pre-college classroom,” said Goldstein.
In Ocala, Collins’ project was in a pool of over 12,000 students’ microgravity experiment proposals. She hopes to one day be a marine biologist and said finalizing the proposal was a great real-world experience.
“I learned how to research well,” she said.
Lisa Fontaine-Dorsey, the gifted resource teacher and lab teacher for science, technology, engineering, art and math at Dr. N.H. Jones Elementary, advised Collins. She began her teaching career in 1992 and was a Golden Apple recipient and named teacher of the year in 1998.
Dorsey said administrators have allowed her to teach outside the box to motivate her students.
“They choose their experiment,” said Dorsey. “They do it all, they take it and run with it.”
Collins’ father, Ole Sheldon, teaches accounting at the College of Central Florida in Ocala. He said when Collins’ proposal wasn’t selected the first time, she still gained something from it.
“We encourage her – and she hates the word – but we encourage her to fail as often as possible, actually, because we just keep failing our way up,” he said.
Collins’ experiment is set to launch in June, although spaceflights routinely get delayed.
Dorsey was especially excited to have girls making proposals this year.
“I think that STEAM education is so important for girls,” she said, referring to science, technology, education, arts and math. “They seem to drop off from that and I’m all about girl power, so I was really proud that we had a bunch of girls involved this time, too.”
Art was added to STEM and became STEAM in 2012 but only recently started showing up in classrooms. It was added to increase creativity and visual learning.
Another project from Dorsey’s elementary school was selected previously.Fifth graders studied fermentation in space, which can be used to produce medicines and other products. It launched in November 2022 and returned to earth in January.
Aarya and Anakan, both 11, are now sixth-graders at Howard Middle School but came up with their project when they were in the fifth grade. They started in September 2021, and it was launched into space Nov. 26, 2022, and returned to earth Jan. 11.
Collins said she has no desire to fly in space herself, but she and her former teacher will travel to Florida’s Space Coast to watch the rocket launch.
“I’m so happy,” she said. “I’m really excited.”

Sat / act prep online guides and tips, 37 cool science experiments for kids to do at home.
General Education
Are you looking for cool science experiments for kids at home or for class? We've got you covered! We've compiled a list of 37 of the best science experiments for kids that cover areas of science ranging from outer space to dinosaurs to chemical reactions. By doing these easy science experiments, kids will make their own blubber and see how polar bears stay warm, make a rain cloud in a jar to observe how weather changes, create a potato battery that'll really power a lightbulb, and more.
Below are 37 of the best science projects for kids to try. For each one we include a description of the experiment, which area(s) of science it teaches kids about, how difficult it is (easy/medium/hard), how messy it is (low/medium/high), and the materials you need to do the project. Note that experiments labelled "hard" are definitely still doable; they just require more materials or time than most of these other science experiments for kids.
#1: Insect Hotels
- Teaches Kids About: Zoology
- Difficulty Level: Medium
- Messiness Level: Medium
Insect hotels can be as simple (just a few sticks wrapped in a bundle) or as elaborate as you'd like, and they're a great way for kids to get creative making the hotel and then get rewarded by seeing who has moved into the home they built. After creating a hotel with hiding places for bugs, place it outside (near a garden is often a good spot), wait a few days, then check it to see who has occupied the "rooms." You can also use a bug ID book or app to try and identify the visitors.
- Materials Needed
- Shadow box or other box with multiple compartments
- Hot glue gun with glue
- Sticks, bark, small rocks, dried leaves, bits of yarn/wool, etc.
#2: DIY Lava Lamp
- Teaches Kids About: Chemical reactions
- Difficulty Level: Easy
In this quick and fun science experiment, kids will mix water, oil, food coloring, and antacid tablets to create their own (temporary) lava lamp . Oil and water don't mix easily, and the antacid tablets will cause the oil to form little globules that are dyed by the food coloring. Just add the ingredients together and you'll end up with a homemade lava lamp!
- Vegetable oil
- Food coloring
- Antacid tablets
#3: Magnetic Slime
- Teaches Kids About: Magnets
- Messiness Level: High (The slime is black and will slightly dye your fingers when you play with it, but it washes off easily.)
A step up from silly putty and Play-Doh, magnetic slime is fun to play with but also teaches kids about magnets and how they attract and repel each other. Some of the ingredients you aren't likely to have around the house, but they can all be purchased online. After mixing the ingredients together, you can use the neodymium magnet (regular magnets won't be strong enough) to make the magnetic slime move without touching it!
- Liquid starch
- Adhesive glue
- Iron oxide powder
- Neodymium (rare earth) magnet
#4: Baking Soda Volcanoes
- Teaches Kids About: Chemical reactions, earth science
- Difficulty Level: Easy-medium
- Messiness Level: High
Baking soda volcanoes are one of the classic science projects for kids, and they're also one of the most popular. It's hard to top the excitement of a volcano erupting inside your home. This experiment can also be as simple or in-depth as you like. For the eruption, all you need is baking soda and vinegar (dishwashing detergent adds some extra power to the eruption), but you can make the "volcano" as elaborate and lifelike as you wish.
- Baking soda
- Dishwashing detergent
- Large mason jar or soda bottle
- Playdough or aluminum foil to make the "volcano"
- Additional items to place around the volcano (optional)
- Food coloring (optional)
#5: Tornado in a Jar
- Teaches Kids About: Weather
- Messiness Level: Low
This is one of the quick and easy and science experiments for kids to teach them about weather. It only takes about five minutes and a few materials to set up, but once you have it ready you and your kids can create your own miniature tornado whose vortex you can see and the strength of which you can change depending on how quickly you swirl the jar.
- Glitter (optional)
#6: Colored Celery Experiment
- Teaches Kids About: Plants
This celery science experiment is another classic science experiment that parents and teachers like because it's easy to do and gives kids a great visual understanding of how transpiration works and how plants get water and nutrients. Just place celery stalks in cups of colored water, wait at least a day, and you'll see the celery leaves take on the color of the water. This happens because celery stalks (like other plants) contain small capillaries that they use to transport water and nutrients throughout the plant.
- Celery stalks (can also use white flowers or pale-colored cabbage)
#7: Rain Cloud in a Jar
This experiment teaches kids about weather and lets them learn how clouds form by making their own rain cloud . This is definitely a science project that requires adult supervision since it uses boiling water as one of the ingredients, but once you pour the water into a glass jar, the experiment is fast and easy, and you'll be rewarded with a little cloud forming in the jar due to condensation.
- Glass jar with a lid
- Boiling water
- Aerosol hairspray
#8: Edible Rock Candy
- Teaches Kids About: Crystal formation
It takes about a week for the crystals of this rock candy experiment to form, but once they have you'll be able to eat the results! After creating a sugar solution, you'll fill jars with it and dangle strings in them that'll slowly become covered with the crystals. This experiment involves heating and pouring boiling water, so adult supervision is necessary, once that step is complete, even very young kids will be excited to watch crystals slowly form.
- Large saucepan
- Clothespins
- String or small skewers
- Candy flavoring (optional)
#9: Water Xylophone
- Teaches Kids About: Sound waves
With just some basic materials you can create your own musical instrument to teach kids about sound waves. In this water xylophone experiment , you'll fill glass jars with varying levels of water. Once they're all lined up, kids can hit the sides with wooden sticks and see how the itch differs depending on how much water is in the jar (more water=lower pitch, less water=higher pitch). This is because sound waves travel differently depending on how full the jars are with water.
- Wooden sticks/skewers
#10: Blood Model in a Jar
- Teaches Kids About: Human biology
This blood model experiment is a great way to get kids to visual what their blood looks like and how complicated it really is. Each ingredient represents a different component of blood (plasma, platelets, red blood cells, etc.), so you just add a certain amount of each to the jar, swirl it around a bit, and you have a model of what your blood looks like.
- Empty jar or bottle
- Red cinnamon candies
- Marshmallows or dry white lima beans
- White sprinkles
#11: Potato Battery
- Teaches Kids About: Electricity
- Difficulty Level: Hard
Did you know that a simple potato can produce enough energy to keep a light bulb lit for over a month? You can create a simple potato battery to show kids. There are kits that provide all the necessary materials and how to set it up, but if you don't purchase one of these it can be a bit trickier to gather everything you need and assemble it correctly. Once it's set though, you'll have your own farm grown battery!
- Fresh potato
- Galvanized nail
- Copper coin
#12: Homemade Pulley
- Teaches Kids About: Simple machines
This science activity requires some materials you may not already have, but once you've gotten them, the homemade pulley takes only a few minutes to set up, and you can leave the pulley up for your kids to play with all year round. This pulley is best set up outside, but can also be done indoors.
- Clothesline
- 2 clothesline pulleys
#13: Light Refraction
- Teaches Kids About: Light
This light refraction experiment takes only a few minutes to set up and uses basic materials, but it's a great way to show kids how light travels. You'll draw two arrows on a sticky note, stick it to the wall, then fill a clear water bottle with water. As you move the water bottle in front of the arrows, the arrows will appear to change the direction they're pointing. This is because of the refraction that occurs when light passes through materials like water and plastic.
- Sticky note
- Transparent water bottle
#14: Nature Journaling
- Teaches Kids About: Ecology, scientific observation
A nature journal is a great way to encourage kids to be creative and really pay attention to what's going on around them. All you need is a blank journal (you can buy one or make your own) along with something to write with. Then just go outside and encourage your children to write or draw what they notice. This could include descriptions of animals they see, tracings of leaves, a drawing of a beautiful flower, etc. Encourage your kids to ask questions about what they observe (Why do birds need to build nests? Why is this flower so brightly colored?) and explain to them that scientists collect research by doing exactly what they're doing now.
- Blank journal or notebook
- Pens/pencils/crayons/markers
- Tape or glue for adding items to the journal
#15: DIY Solar Oven
- Teaches Kids About: Solar energy
This homemade solar oven definitely requires some adult help to set up, but after it's ready you'll have your own mini oven that uses energy from the sun to make s'mores or melt cheese on pizza. While the food is cooking, you can explain to kids how the oven uses the sun's rays to heat the food.
- Aluminum foil
- Knife or box cutter
- Permanent marker
- Plastic cling wrap
- Black construction paper
#16: Animal Blubber Simulation
- Teaches Kids About: Ecology, zoology
If your kids are curious about how animals like polar bears and seals stay warm in polar climates, you can go beyond just explaining it to them; you can actually have them make some of their own blubber and test it out. After you've filled up a large bowl with ice water and let it sit for a few minutes to get really cold, have your kids dip a bare hand in and see how many seconds they can last before their hand gets too cold. Next, coat one of their fingers in shortening and repeat the experiment. Your child will notice that, with the shortening acting like a protective layer of blubber, they don't feel the cold water nearly as much.
- Bowl of ice water
#17: Static Electricity Butterfly
This experiment is a great way for young kids to learn about static electricity, and it's more fun and visual than just having them rub balloons against their heads. First you'll create a butterfly, using thick paper (such as cardstock) for the body and tissue paper for the wings. Then, blow up the balloon, have the kids rub it against their head for a few seconds, then move the balloon to just above the butterfly's wings. The wings will move towards the balloon due to static electricity, and it'll look like the butterfly is flying.
- Tissue paper
- Thick paper
- Glue stick/glue
#18: Edible Double Helix
- Teaches Kids About: Genetics
If your kids are learning about genetics, you can do this edible double helix craft to show them how DNA is formed, what its different parts are, and what it looks like. The licorice will form the sides or backbone of the DNA and each color of marshmallow will represent one of the four chemical bases. Kids will be able to see that only certain chemical bases pair with each other.
- 2 pieces of licorice
- 12 toothpicks
- Small marshmallows in 4 colors (9 of each color)
- 5 paperclips
#19: Leak-Proof Bag
- Teaches Kids About: Molecules, plastics
This is an easy experiment that'll appeal to kids of a variety of ages. Just take a zip-lock bag, fill it about ⅔ of the way with water, and close the top. Next, poke a few sharp objects (like bamboo skewers or sharp pencils) through one end and out the other. At this point you may want to dangle the bag above your child's head, but no need to worry about spills because the bag won't leak? Why not? It's because the plastic used to make zip-lock bags is made of polymers, or long chains of molecules that'll quickly join back together when they're forced apart.
- Zip-lock bags
- Objects with sharp ends (pencils, bamboo skewers, etc.)
#20: How Do Leaves Breathe?
- Teaches Kids About: Plant science
It takes a few hours to see the results of this leaf experiment , but it couldn't be easier to set up, and kids will love to see a leaf actually "breathing." Just get a large-ish leaf, place it in a bowl (glass works best so you can see everything) filled with water, place a small rock on the leaf to weigh it down, and leave it somewhere sunny. Come back in a few hours and you'll see little bubbles in the water created when the leaf releases the oxygen it created during photosynthesis.
- Large bowl (preferably glass)
- Magnifying glass (optional)
#21: Popsicle Stick Catapults
Kids will love shooting pom poms out of these homemade popsicle stick catapults . After assembling the catapults out of popsicle sticks, rubber bands, and plastic spoons, they're ready to launch pom poms or other lightweight objects. To teach kids about simple machines, you can ask them about how they think the catapults work, what they should do to make the pom poms go a farther/shorter distance, and how the catapult could be made more powerful.
- Popsicle sticks
- Rubber bands
- Plastic spoons
- Paint (optional)
#22: Elephant Toothpaste
You won't want to do this experiment near anything that's difficult to clean (outside may be best), but kids will love seeing this " elephant toothpaste " crazily overflowing the bottle and oozing everywhere. Pour the hydrogen peroxide, food coloring, and dishwashing soap into the bottle, and in the cup mix the yeast packet with some warm water for about 30 seconds. Then, add the yeast mixture to the bottle, stand back, and watch the solution become a massive foamy mixture that pours out of the bottle! The "toothpaste" is formed when the yeast removed the oxygen bubbles from the hydrogen peroxide which created foam. This is an exothermic reaction, and it creates heat as well as foam (you can have kids notice that the bottle became warm as the reaction occurred).
- Clean 16-oz soda bottle
- 6% solution of hydrogen peroxide
- 1 packet of dry yeast
- Dishwashing soap
#23: How Do Penguins Stay Dry?
Penguins, and many other birds, have special oil-producing glands that coat their feathers with a protective layer that causes water to slide right off them, keeping them warm and dry. You can demonstrate this to kids with this penguin craft by having them color a picture of a penguin with crayons, then spraying the picture with water. The wax from the crayons will have created a protective layer like the oil actual birds coat themselves with, and the paper won't absorb the water.
- Penguin image (included in link)
- Spray bottle
- Blue food coloring (optional)
#24: Rock Weathering Experiment
- Teaches Kids About: Geology
This mechanical weathering experiment teaches kids why and how rocks break down or erode. Take two pieces of clay, form them into balls, and wrap them in plastic wrap. Then, leave one out while placing the other in the freezer overnight. The next day, unwrap and compare them. You can repeat freezing the one piece of clay every night for several days to see how much more cracked and weathered it gets than the piece of clay that wasn't frozen. It may even begin to crumble. This weathering also happens to rocks when they are subjected to extreme temperatures, and it's one of the causes of erosion.
- Plastic wrap
#25: Saltwater Density
- Teaches Kids About: Water density
For this saltwater density experiment , you'll fill four clear glasses with water, then add salt to one glass, sugar to one glass, and baking soda to one glass, leaving one glass with just water. Then, float small plastic pieces or grapes in each of the glasses and observe whether they float or not. Saltwater is denser than freshwater, which means some objects may float in saltwater that would sink in freshwater. You can use this experiment to teach kids about the ocean and other bodies of saltwater, such as the Dead Sea, which is so salty people can easily float on top of it.
- Four clear glasses
- Lightweight plastic objects or small grapes
#26: Starburst Rock Cycle
With just a package of Starbursts and a few other materials, you can create models of each of the three rock types: igneous, sedimentary, and metamorphic. Sedimentary "rocks" will be created by pressing thin layers of Starbursts together, metamorphic by heating and pressing Starbursts, and igneous by applying high levels of heat to the Starbursts. Kids will learn how different types of rocks are forms and how the three rock types look different from each other.
- Toaster oven
#27: Inertia Wagon Experiment
- Teaches Kids About: Inertia
This simple experiment teaches kids about inertia (as well as the importance of seatbelts!). Take a small wagon, fill it with a tall stack of books, then have one of your children pull it around then stop abruptly. They won't be able to suddenly stop the wagon without the stack of books falling. You can have the kids predict which direction they think the books will fall and explain that this happens because of inertia, or Newton's first law.
- Stack of books
#28: Dinosaur Tracks
- Teaches Kids About: Paleontology
How are some dinosaur tracks still visible millions of years later? By mixing together several ingredients, you'll get a claylike mixture you can press your hands/feet or dinosaur models into to make dinosaur track imprints . The mixture will harden and the imprints will remain, showing kids how dinosaur (and early human) tracks can stay in rock for such a long period of time.
- Used coffee grounds
- Wooden spoon
- Rolling pin
#29: Sidewalk Constellations
- Teaches Kids About: Astronomy
If you do this sidewalk constellation craft , you'll be able to see the Big Dipper and Orion's Belt in the daylight. On the sidewalk, have kids draw the lines of constellations (using constellation diagrams for guidance) and place stones where the stars are. You can then look at astronomy charts to see where the constellations they drew will be in the sky.
- Sidewalk chalk
- Small stones
- Diagrams of constellations
#30: Lung Model
By building a lung model , you can teach kids about respiration and how their lungs work. After cutting off the bottom of a plastic bottle, you'll stretch a balloon around the opened end and insert another balloon through the mouth of the bottle. You'll then push a straw through the neck of the bottle and secure it with a rubber band and play dough. By blowing into the straw, the balloons will inflate then deflate, similar to how our lungs work.
- Plastic bottle
- Rubber band
#31: Homemade Dinosaur Bones
By mixing just flour, salt, and water, you'll create a basic salt dough that'll harden when baked. You can use this dough to make homemade dinosaur bones and teach kids about paleontology. You can use books or diagrams to learn how different dinosaur bones were shaped, and you can even bury the bones in a sandpit or something similar and then excavate them the way real paleontologists do.
- Images of dinosaur bones
#32: Clay and Toothpick Molecules
There are many variations on homemade molecule science crafts . This one uses clay and toothpicks, although gumdrops or even small pieces of fruit like grapes can be used in place of clay. Roll the clay into balls and use molecule diagrams to attach the clay to toothpicks in the shape of the molecules. Kids can make numerous types of molecules and learn how atoms bond together to form molecules.
- Clay or gumdrops (in four colors)
- Diagrams of molecules
#33: Articulated Hand Model
By creating an articulated hand model , you can teach kids about bones, joints, and how our hands are able to move in many ways and accomplish so many different tasks. After creating a hand out of thin foam, kids will cut straws to represent the different bones in the hand and glue them to the fingers of the hand models. You'll then thread yarn (which represents tendons) through the straws, stabilize the model with a chopstick or other small stick, and end up with a hand model that moves and bends the way actual human hands do.
- Straws (paper work best)
- Twine or yarn
#34: Solar Energy Experiment
- Teaches Kids About: Solar energy, light rays
This solar energy science experiment will teach kids about solar energy and how different colors absorb different amounts of energy. In a sunny spot outside, place six colored pieces of paper next to each other, and place an ice cube in the middle of each paper. Then, observe how quickly each of the ice cubes melt. The ice cube on the black piece of paper will melt fastest since black absorbs the most light (all the light ray colors), while the ice cube on the white paper will melt slowest since white absorbs the least light (it instead reflects light). You can then explain why certain colors look the way they do. (Colors besides black and white absorb all light except for the one ray color they reflect; this is the color they appear to us.)
- 6 squares of differently colored paper/cardstock (must include black paper and white paper)
#35: How to Make Lightning
- Teaches Kids About: Electricity, weather
You don't need a storm to see lightning; you can actually create your own lightning at home . For younger kids this experiment requires adult help and supervision. You'll stick a thumbtack through the bottom of an aluminum tray, then stick the pencil eraser to the pushpin. You'll then rub the piece of wool over the aluminum tray, and then set the tray on the Styrofoam, where it'll create a small spark/tiny bolt of lightning!
- Pencil with eraser
- Aluminum tray or pie tin
- Styrofoam tray
#36: Tie-Dyed Milk
- Teaches Kids About: Surface tension
For this magic milk experiment , partly fill a shallow dish with milk, then add a one drop of each food coloring color to different parts of the milk. The food coloring will mostly stay where you placed it. Next, carefully add one drop of dish soap to the middle of the milk. It'll cause the food coloring to stream through the milk and away from the dish soap. This is because the dish soap breaks up the surface tension of the milk by dissolving the milk's fat molecules.
- Shallow dish
- Milk (high-fat works best)
#37: How Do Stalactites Form?
Have you ever gone into a cave and seen huge stalactites hanging from the top of the cave? Stalactites are formed by dripping water. The water is filled with particles which slowly accumulate and harden over the years, forming stalactites. You can recreate that process with this stalactite experiment . By mixing a baking soda solution, dipping a piece of wool yarn in the jar and running it to another jar, you'll be able to observe baking soda particles forming and hardening along the yarn, similar to how stalactites grow.
- Safety pins
- 2 glass jars

45 Easy Science Experiments for Kids
Hello, STEM! These simple DIY activities can be done at home or in school.
Imagine blowing the biggest bubbles imaginable — or even making bubbles within bubbles. Or sending vessels — rockets, tea bags, airplanes — soaring through the sky for impossible distances. Now imagine making things explode, or change colors, or reveal hidden messages with just a few simple mixtures.
First off, it's good to start them off with the scientific method. Give them a journal to record their observations, questions, hypotheses, experiments, results and conclusions. As always, safety counts: wear goggles and coats or aprons if need be (sometimes kids get a kick out of how scientific the protective gear makes them look), and always make sure that the kids are supervised when doing them. (Warning: Some of these are messy!)
These experiments are mostly designed for preschoolers through elementary schoolers — with a couple that are either demonstrations or better for older kids — but if you have a younger one, you can check out these 1-year-old learning activities , toddler learning activities and preschool/kindergarten learning activities , some of which also cover STEM subjects.
Floating Fish
Here's another one that deals with solubility and density.
- Draw the outline of a fish on the bottom of a glass plate or tray in dry-erase marker. Retrace your drawing to make sure all the lines are connected. Let dry for a minute or two.
- Fill the measuring cup with tap water. Place the pour spout just inside the corner of the dish and add water very slowly until it just covers the bottom. Be careful not to pour water directly onto your drawing or make splashes near it. The water will move toward your drawing, eventually surrounding it. Observe what happens. If the water splashes or it doesn’t work on your first try, empty the dish, erase the drawing with a paper towel, dry off the dish, and try again.
- Tilt the dish slightly from side to side. What happens? Jot it down.
The ink in dry erase markers is engineered to be slippery. It’s made with a chemical that causes it to easily release from surfaces. (Permanent markers are made with a chemical that makes the ink stick to surfaces, so be sure not to use these in your experiment!)
The easy-release ink lets go from a surface, but why does it float? There are two reasons. First, dry erase ink isn’t soluble, which means it won’t dissolve in water. Second, dry erase ink is less dense than the water, so it becomes buoyant, meaning it can float. When you tilt the dish, the fish moves around on the water’s surface.

Brush, Brush!
This one will really get them into brushing their teeth once they scientifically prove all the good things that toothpaste can do.
- Write on sticky notes: Soda 1, Soda 2, Juice 1, and Juice 2. Place them in a row on a counter.
- Fill two glasses halfway with brown soda and place behind the Soda 1 and Soda 2 sticky notes. Fill two glasses halfway with lemon juice and place behind the Juice 1 and Juice 2 sticky notes.
- Carefully place one egg in the bowl. Squeeze a big dollop — about one tablespoon — of toothpaste on top of the egg and gently rub the toothpaste all around with your hands until the egg is completely covered in a thick layer of toothpaste. Repeat with a second egg.
- Gently submerge the toothpaste-covered eggs into the liquids: one egg in the glass labeled Soda 1 and the other egg in the glass labeled Juice 1. Wash and dry your hands.
- Gently submerge the remaining eggs, without toothpaste on them, in the remaining glasses: one in the glass labeled Soda 2 and the other in the glass of juice labeled Juice 2. Wash and dry your hands. Leave the eggs in the glasses for 12 hours.
- After 12 hours, remove the eggs from the glasses of soda one at a time. Rinse them in cool water and pat them dry with the towel. Place each egg by the sticky note of the glass it was in. Are the eggs the same or different colors?
- Remove the eggs from the glasses of juice one at a time. Rinse them under the faucet and pat them dry. Place each egg by the sticky note of the glass it was in. Feel the eggs gently. Does one feel stronger or weaker than the other?
- Write down your observations in your science notebook.
The eggshells in this experiment represent the enamel (outer coating) on your teeth. Toothpaste cleans your teeth and prevents stains: it removes food and drink particles that are stuck on your teeth. Teeth can be stained easily by dark-colored liquids like cola, coffee or tea. The egg without toothpaste will be brown and discolored. The egg covered in toothpaste was protected from turning brown.
Toothpaste also protects your pearly whites from decay (breaking down). The egg without toothpaste left in the lemon juice was worn down and soft to the touch, while the egg that was protected with toothpaste is stronger. The lemon juice is acidic, and those acids broke down the shell just as acidic drinks can wear away your tooth enamel. When a tooth is worn down, a cavity can form more easily. But the fluoride in toothpaste mixes with your saliva to create a protective coating around your tooth enamel. It helps keep your teeth strong and cavity-free.
Grow an Avocado Tree
For an easy lesson in Earth Science, your family can grow an avocado tree from a pit. You can buy an AvoSeedo kit , or just peel the seed and suspend it over water with toothpicks.

Milk Bottle Xylophone
No for an experiment in sound!
- Arrange six glass jars or bottles, all the same size with no lids, in a line. What will each jar sound like when you tap it with a spoon? Make a prediction, then tap each jar. Record your observations.
- Next, put water in each of the jars. Pour 1⁄4 cup (60 ml) of water into the first jar. Add 1⁄2 cup (120 ml) of water to the second jar. Continue in 1⁄4-cup increments, adding 3⁄4 cup (180 ml) of water to the third jar, 1 cup (240 ml) of water to the fourth jar, 11⁄4 cups (300 ml) of water to the fifth jar, and 11⁄2 cups (360 ml) to the sixth jar. Add a couple of drops of food coloring to each jar.
- What will each jar sound like? Will they sound the same or different than when the container was empty? Will they sound the same or different from one another? Record your predictions.
- Tap each jar with a metal spoon. Write down your observations about each jar’s pitch (how high or low a sound is) in your notebook.
Sound waves are created by vibrations, which are back-and-forth movements that are repeated again and again. Pitch depends on the frequency of the waves — how many are created each second. A high pitch is created by high-frequency sound waves, and can sound squeaky. A low pitch is created by low-frequency sound waves, and sounds deep and booming.
When you tapped the jar, it vibrated. The vibrations traveled from the jar to the water to the air and eventually to your ears. The jars with more water had a low pitch. The sound waves vibrated more slowly because they had more water to travel through. The jars with less water had higher pitches. The sound waves vibrated faster because they had less water to travel through. A jar with no water in it makes the highest pitch because it has the least substance to travel through.
"Elephant Toothpaste"
Okay, elephants don't really brush with this stuff, which is made from a chemical reaction between hydrogen peroxide, yeast, dish soap and a few other simple ingredients. But this experiment has a big "wow" factor since, when the substances are mixed, the "toothpaste" foams out of the bottle. You can use it to teach kids about catalysts and exothermic reactions.

Challenge your little scientist to lift up an ice cube with just a piece of string. It's possible ... with a little salt to help. Salt melts the ice and lowers the freezing point of the ice cube, which absorbs the heat from the water around it, making the water cold enough to re-freeze around the string.

Coin Inertia
Stack up about five or so coins on a piece of cardboard and place it over a glass of water. Then, flick the cardboard out from on top of the glass. Do the coins drop into the water, or ride with the cardboard? Due to inertia, they drop into the water — a very visual (and fun!) demonstration of Newton's First Law of Motion.

Apple Oxidation
What works best for keeping an apple from turning brown? Test to find out! Slice up an apple, and let each slice soak in a different liquid. Then take them out, lay them on a tray, and check the brownness after three minutes, six minutes and so on. Not only does this test the properties of different liquids, it also helps students practice the scientific method if they create hypotheses about which liquids would be most effective.

Chromatography Flowers
Chromatography is the process of separating a solution into different parts — like the pigments in the ink used in markers. If you draw stripes around a coffee filter, then fold it up and dip the tip in water, the water will travel up the filter and separate the marker ink into its different pigments (in cool patterns that you can display as a craft project). This family made the end-result even brighter by adding an LED circuit to the center.

Water Walking
You'll need six containers of water for this one: three with clear water, one with red food coloring, one with blue coloring, and one with yellow coloring. Arrange them in a circle, alternating colored and clear containers, and make bridges between the containers with folded paper towels. Your kids will be amazed to see the colored water "walk" over the bridges and into the clear containers, mixing colors, and giving them a first-hand look at the magic of capillarity.

Sagarmala projects worth Rs 1 lakh cr identified in Andhra Pradesh: Shipping Minister
Launched in march 2015, the sagarmala programme includes projects from various categories, such as modernisation of existing ports and terminals, new ports, terminals, ro-ro roll onroll off tourism jetties, enhancement of port connectivity, inland waterways, lighthouse tourism, industrialisation around ports, skill development, and technology centres..
More than 110 projects worth around Rs 1.1 lakh crore have been identified in Andhra Pradesh under Sagarmala, even as 35 works worth Rs 32,000 crore have already been completed, Union Minister of Ports and Shipping Sarbananda Sonowal said on Saturday here.
Speaking at the Global Investors' Summit being held here, he said some of the projects are focused on roll on roll off (RORO), passenger jetty, fishing, port modernisation and skill development among others.
According to the Minister, Visakhapatnam Port has exhibited a healthy cargo growth of over 7.5 per cent in 2022–23.
''Following directions from the Ministry, the port is in the process of transforming as a landlord port. Other ports also may comply by 2023,'' said the Shipping Minister.
He said six projects are operating in Visakhapatnam Port, awarded in January 2023 with an investment of Rs 658 crore.
Further elaborating, Sonowal said the Ministry of Ports, Shipping, and Water in association with the Ministry of Fishing is upgrading fishing harbours all over India as per international standards.
As many as 31 such harbours will be developed under Sagarmala and Pradhan Mantri Macha Sampada Yojana, he said.
Likewise, the fishing harbour at Visakhapatnam is being upgraded at a cost of Rs 151 crore, which will result in improving the quality of life of the local fishing community.
Moreover, the Union Minister noted that the international cruise terminal in the port city of Visakhapatnam is nearing completion at a cost of Rs 97 crore, and is likely to start operations from April.
Sharing information on achievements at the national level, Sonowal said cargo handling capacity has risen by 79 per cent in the past nine years, including merchandise exports touching a value of $421 billion in 2021–2022. Launched in March 2015, the Sagarmala programme includes projects from various categories, such as modernisation of existing ports and terminals, new ports, terminals, Ro-Ro (Roll on/Roll off) & tourism jetties, enhancement of port connectivity, inland waterways, lighthouse tourism, industrialisation around ports, skill development, and technology centres.
