Science Fair project ideas and experiments you can do


Science fairs and exhibitions are something towards which a student is always looking forward. But then again a problem they find is that they are unable to come up with the unique experiments or projects for their science exhibition whether in chemistry, physics, biology or any other field. So, we are here to present some of the best science fair project ideas and experiments you can actually do.


1) Making a model of the Dead Sea

The Dead Sea is a place of great interest for those who love the science of chemistry and physics. The reason behind its secret is density. So all you have to do is make a model in which you will make anything float. For example; an egg floats on water because its density is higher than that of water and vice versa. It tells us that if the ratio of water density to the other objects density is higher, then that object will hover on the surface, and if the rate of water density to any other object is lower, then that object will descend to the bottom. So using salt or any other chemical makes this Dead Sea and can surprise anyone. This science project is one of the best in many of the US elementary schools and is enjoyed by the younger students.

2) Creating a volcanic lamp

Simulating a volcanic eruption is a simple experiment and an easier one for anyone to perform. Here is a unique project for elementary school students to accomplish just using oil, water, a container, some colors and some fizz creating tablet (CO2 releaser), that will amaze everyone around them. Oil is non-polar and lower in density than water so it remains on the top surface of the water and does not blend in, and the colors, being polar, get dissolved in the water. After adding the tablets (e.g. Alka seltzer tablets) BOOM! We get colored bubbles and a mesmerizing lamp.

3) A fountain of mint candy and soda

One of the most famous experiment being performed by middle school students is making a fountain of mint candy like mentos and soda. No doubt it is a natural experiment with a lot of fun. This fountain can reach a height of 6 FEET!! Amazing right? So what are you waiting for, go, perform, enjoy and have some FUN! NOTE: a piece of great advice from us is that you should perform this experiment in an open space. Actually what happens is that the candy produces carbon dioxide after reacting with the soda in large amount, and in time, we face an impressive efflux of the mixer.

4) Checking students’ conformity

A fantastic experiment for high school kids is related to students’ behavior or people’s behavior between a large group of individuals. What it requires is just a classroom with a teacher and students, and all you have to do is observe and make your hypothesis and queries about it. A question is asked by a teacher from the class: What is 11 into 13? And many of the students will say 133. Those who know the correct answer are influenced by the confidence and wrong answers of others and are unable to give their real answers. Instead they will start to believe that 133 is the correct one, not 143. You need to study this student conformity and the degree of its peer pressure.

5) Production of electrical current through fruit

It will sound crazy because we all know that fruit do not possess any electric current or electric charge, but still, they can be used as a battery if they are placed in between two metals and you will see a change of electric charge.

Most of the time the fruit used in this experiment is lemon along with a piece of iron and a piece of copper, but you can also use some vegetables. An LED light is used to show the results. Also, if you want to make your experiment look more professional, then you can use a simple and cheaper voltage reader which will be computing the amount of voltage passing through the fruit.
