This project demonstrates the correspondence between the volume of water displaced by a submerged object and the volume of the object displacing it.

This science fair project idea produces sounds by creating vibrations using different objects.

What is elasticity? Students will investigate how this concept applies to bouncing ball physics by testing the bounces of balls made out of different materials.

By using static electricity generated from their body, a child can cause a small fluorescent lamp bulb to light up!

Students pit the heat capacity of water against the heat capacity of oil while looking at the effects of dipole rotation in this cool science fair project idea.

Discover whether different amounts of water added into a wine glass will produce a different pitch when their fingers are rubbed along the rim.

Using an empty tennis ball can and a swimming pool, you will determine if it's possible to have a conversation under water.

Sink or swim? Calculate the density of various fruits and vegetables using water and a kitchen scale.

Using simple materials found around your home, you can reinforce the static electricity concept by helping your child build a simple device with zapping power!

Turn the common pastime of constructing paper airplanes into a lesson on the physics of aerodynamics and flight with this fun science activity.

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

How do series and parallel circuits work, and which produces the brightest light in a light bulb? Construct both in this project and find out!

Get your fifth grader involved in some earth science by helping her plan and create her very own rock collection.

The objective of this science fair project idea is to determine if sound travels best through the air, water or a solid.
