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

How to make Biofuel  (biogas, methane) from manure and water

How to make Biofuel (biogas, methane) from manure and water

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

DO PLANTS GROW TOWARDS LIGHT: BIOLOGY SCIENCE FAIR PROJECT ON PHOTOTROPISM

DO PLANTS GROW TOWARDS LIGHT: BIOLOGY SCIENCE FAIR PROJECT ON PHOTOTROPISM

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: EXPERIMENT WITH POTATO

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

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

HOW TO MAKE PULSE COUNTER

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. Extraction of DNA from banana

Biology Experiment - How to Extract DNA From a Banana

Biology Experiment - How to Extract DNA From a 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

HOW TO MAKE WORKING MODEL OF HEART AND CIRCULATORY SYSTEM OF HUMAN FOR SCIENCE PROJECT

HOW TO MAKE WORKING MODEL OF HEART AND CIRCULATORY SYSTEM OF HUMAN FOR SCIENCE PROJECT

Our favorite project among students is the model of the heart. This project doesn't require a long list of material. You can make it by using physio ball, PVC pipe cap, balloons, and drip pipe. You can easily complete this project in an hour or so. This working model of heart project is sure to impress your teachers and classmates.
