Introduce your child to science with something they see everyday--their shadow!

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

How does a kazoo, the strings of a guitar, or the speaker of a radio make sound? The purpose of this science fair project is to show how vibration makes sound.

Science fair project that examines what causes thunder and why a thunderclap sounds so loud. How is lightening related to the creation of sound waves?

Air invisible; it doesn't make sounds; you can't pick it up and throw it. So how do we know it exists? Help your second grade scientist figure it out.

How does the size of a vibrating surface affect the pitch of a drum? Learn about drum size and pitch with this easy science fair project idea.

Learn to solve a crime scene investigation using an important forensics tool: oblique lighting.

Your third grader will delight in learning about sound waves as he observes the different sounds created by tapping on glasses with varying amounts of water.

Your child will learn science and make a fun new malleable toy with this balloon sandbag science experiment.

In this physics project, learn about the relationship between light intensity and distance using a laser pointer, flashlight, and graph paper!
