This project compares test subjects' responses to whining and other "attachment" and attention-getting sounds to determine which sounds are most distracting.

Satisfy your kindergartener's fascination of different sounds with this easy science project, where they'll use their ears instead of their eyes to identify sounds!

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.

In this activity, you'll send your kindergartener on a scavenger hunt to find sounds and create a sound recording. Here's how!

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.

Before Twitter, birds were the ones tweeting, not humans. Have your child discover the magical sounds of nature while recording birds around his neighborhood!

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.

Brighten up your home with this fun activity! Make a summer sun print and teach your child the art of easy print making.

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.

Find out if most people can distinguish the difference between tones on different instruments.

Take a closer look at your furry friend (or the furry friend of a neighbor -- with permission) to discover if communication exists between cats and humans.

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.

Reuse and recycle cardboard tubes to make spooky spiders, kooky caterpillars, wacky worms, and more.

This project explores whether similar type movie scenes are accompanied by music with similar characteristics.

Learn about sound physics and do a survey experiment to explore the difference between sound and noise in this science project.

This play-activity causes young children to focus on and become more aware of their sense of hearing and the power of their ears.

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

Show your middle schooler how a quick whirl of spinach in the blender will reveal the cobwebby "stuff"--or DNA--of life!

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.

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

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

This science fair project idea examines if there is a reason that musical notes are at the pitches they are.

Research camouflage products and techniques, test quality by timing volunteers. Calculate the average length of time to recognize the subject.
