This experiment investigates whether there are certain sounds that affect men and women differently

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.

Demonstrate how we are able to locate sounds, echolocation. Have a blindfolded subject locate you by the sound of your clapping.

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.

In this project students determine which instruments composers use to create birdsongs and birdcalls in classical music.

Find out the differences (if any) in the frequencies of voices produced from a computer, from a phone, and directly coming out of the voice box of a human.

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.

This science fair project idea produces varying pitches of sound.

This project determines what percentage of test subjects react adversely to the sound of fingernails on a chalkboard and explores their physiological responses.

Little scientists will make inferences about hearing loss, pitch, and frequency in this great science fair idea that puts the human ear to the test.

All you need are pencils, paper and some scissors to get started on this easy and fun game to review astronomy information, or other types of study concepts.

Help your child experiment with the combination of acid and baking soda by making these homemade bath bombs!

With this activity, not only will you be experimenting with giving accurate information, you'll also teach your child how to write good scientific procedures.

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

Learn how matter transmits sound with a simple, hands-on experiment using sand, water and air.

What is the Doppler Effect, or the Doppler Shift? The purpose of this science fair project is to determine how distance impacts the Doppler Effect.
