Top 7 Best Biology Projects for Science Fair
Top 7 best biology projects for science fair for classes 6, 7, 8, 9 and 10.
Science exhibitions are a great way to learn different concepts by watching many projects at a time and can meet with the inventors of that project. They provide a platform to share your experiments/ projects/ inventions with people and also get feedback.
Learning about science concepts will be very boring if we just learn the concepts and do not make or use them in real. One can increase learning tenfolds by making things, using different materials, play with them, and see the wonders that you can do.
Here are some most popular experiments of biology projects which are published on Pakistan Science Club portal https://paksc.org/pk/science-experiments/biology-experiments/
Best Biology Projects # 7 Biofuel (biogas, methane) from waste
Biogas is chiefly composed of methane (CH4), is produced from the decomposition of organic matter by bacteria in the absence of oxygen, a process called anaerobic decomposition. Bacteria that can survive without oxygen is called anaerobic bacteria.When you complete the activity you will produce your own biofuel and have studied it.
Best Biology Projects # 6. Do plants grow towards the light
This project investigates a property of plants known as phototropism: that is, their ability to grow toward light sources wherever they may be. You may be surprised at how clever these plants can be, even without a brain.
Best Biology Projects # 5. Osmosis: experiment with potato
Osmosis is the process by which solutions of different concentrations move across semi-permeable membranes from the region of lower concentration into that of higher concentration. Osmotic pressure is the force with which molecules move from the area of its higher concentration into that of its lower concentration.
Best Biology Projects # 4. Lung model science project
Build Your Own Lung Model Science Project
In this lung model science project, the straws represent your trachea and bronchial tubes, the balloons represent your lungs, the bottle is your chest, and the plastic sheet is your diaphragm – a sheet of muscles under your chest. When you breathe in, or inhale, your diaphragm contracts and moves down, creating more space in your chest for your lungs to fill with air. When you exhale (breath out), your diaphragm relaxes back up. The space inside your chest gets smaller forcing the air out of your lungs.
Best Biology Projects # 3. How to make pulse counter
The rhythmical dilation of arteries produced when blood is pumped outward by regular contractions of the heart, especially as palpated at the wrist or in the neck. The pulse is usually felt just inside the wrist below the thumb by placing two or three fingers lightly upon the radial artery.
Best Biology Projects # 2. E xtraction of DNA from banana
Just like us, banana plants have genes and DNA in their cells, and just like us, their DNA determines their traits. Using only our eyes, we couldn't see a single cell or the DNA inside of it. If we remove DNA from millions of cells, however, we will be able to view it without a microscope. That is what we will do today!
Best Biology Projects # 1. Working model of the heart

Biology Projects
Biology is known as the study of all the living organisms and helps us in understanding each and every organism which is alive, right from the tiniest bacteria to the California redwoods and the blue whales. Many professional biologists very often concentrate on the small type of living organisms like the birds, bacteria, plants, etc. Not only them, even many of you might have performed a series of experiments on the Biology projects in your school level.
An insight detail about the life helps us to understand the way of caring for ourselves, plants and the animals in a proper manner. And moreover, Biology helps every individual in the understanding of interaction lying between humanity and also the world. It, in turn, develops a sense of interest among the living organisms in a way that makes an effort in preserving them.
Below are some of the cool experiments that make biology a fascinating subject.
