Demonstrate how you can make your own compass using a magnetized needle. It also allows you to compare magnetic north and geographic north.

This project explores ways to prevent static electrical shocks.

Science fair project in which you will attempt to throw a ball the greatest horizontal distance possible by using different angles.

In this project, waves of vibrations are experimented with using water in glasses.

Experiment with buoyancy to learn how a submarine rises and sinks in this classic science experiment.

The objective of this science fair project is to experiment with balancing everyday objects and observing the the effects of gravity on materials.

Young physicists will wrestle with a discrepant event: the Hammer Ruler Trick. They'll make some inferences about torque, balance, and center of gravity.

This science fair project idea examines liquids of different densities.

Science fair project which determines whether the size or the thickness of a piece of paper has an effect on how many times it can be folded in half.

This science fair project idea investigates how the height at which a pendulum is released affects the length of time it continues.

This science fair project idea discovers whether there are some objects that do not fall at a constant rate.

The objective of this science fair project is to analyze the effects of salinity and temperature on water.

Create a DIY Electromagnet! Using a 9v battery to create an electrical field around a nail, students explore electromagnetism in this cool science project idea.

The goal of this science fair experiment is to demonstrate the effects of air pressure on objects and analyze applications of air pressure principles.

In this Bernoulli's Principle experiment, you'll learn how an increase in the speed of a fluid, like air, decreases pressure.

This science fair project creates a visual model of whatâs happening to sound waves as a car approaches and then leaves.

Science fair project which evaluates different athletic shoes in order to find out whether any of them affect a person's ability to run.

Brine shrimp usually live in saltwater. Investigate how salt concentration (salinity) affects the rate at which brine shrimp eggs hatch.

Science fair project which determines if plants really do need water to grow, or whether they just need to be kept wet.

This science project idea examines the effect of microwaving on various objects.

This science fair project idea examines the reason boats are shaped and engineered.
