How good are humans at sound localization? Kids can try this cool science fair project idea to see how good their friends are at judging sound direction.

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

Every time a sound is produced it emits a sound wave. This experiment demonstrates how sound travels, using nothing more than a spoon and a string!

What causes sound? Here's a simple science experiment that adds a visual element to the science of sound to help kids better understand this tricky concept.

Let your young scientist explore a brave new world of sound with an experiment that just requires a handful of common household items.

This science fair project idea produces varying pitches of 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?

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

Explore how sound waves are reflected and absorbed by producing echoes. Analyze which locations produce echoes.

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.

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

These flying potato poppers make a cool sound, create a celebratory mood, and they can teach your child about the power of air pressure.

This activity challenges students to use computational thinking as they create a sequence of commands that will make a robot move in a pattern related to the sound and rhythm of music.

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

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.

Encourage a group of third graders to play this fun game of Whistle Hide-and-Seek as a warm-up to get them prepared for finding a "lost" camper.

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

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