20 Science Experiments for Middle School Students

Science projects can be a lot of fun, even if you aren’t a science whiz. However, once you are in middle school, the old volcano eruption project just doesn’t cut it. You actually need to demonstrate more complicated scientific principles in action and elaborate on them.

Sounds too difficult? Worry not, we are going to tell you how to perform 20 different science experiments that are guaranteed to shock and awe your classmates and judges. Just go through the guide below to pick and choose any experiment you fancy.

    An Electrochemical Cell

    If you have an interest in electronics and how electrical charges move, you can try to Make an Electrochemical Cell. You will just need two glass beakers and some chemicals along with a voltmeter for this experiment.

    The Amazing Human Battery

    This experiment employs the same principle as that of an electrochemical cell. The only difference is that in Making a Human Battery, you replace the salt bridge with two of your own fingers!

    The Balloon Powered Car

    In this experiment, you have an air-filled balloon that acts as the car’s engine. Air pressure is the driving force here, and it will only take 5 to 10 minutes to Make a Balloon Powered Car for your science experiment.

    Salt Water Conductivity Experiment

    The purpose of behind performing the Salt Water Conductivity Experiment is to prove that a mixture of salt and water forms an electrolyte. This is a simple enough experiment and does not require elaborate equipment.

    Crush the Can Experiment

    This experiment shows the effect of changes in external and internal temperature, in relation to the atmospheric pressure acting on a body. You only need an empty tin with some cold water to perform Crush the Can Experiment.

    Demonstration of Centripetal Force

    An experiment Demonstrating Centripetal Force simply shows that any body, moving in a circle, is acted upon by a force (the Centripetal Force) which directs its motion towards the center.

    Demonstration of Centrifugal Force

    Almost the same as centripetal force, Demonstrating Centrifugal Force shows how a body remains in equilibrium while moving in a circular motion.
