Find a mathematical relationship between the intensity of a sound wave and distance from the sound source. Use a pedometer and a sound level meter.

In this cool sound resonance experiment, learn about frequency and pitch, and use a tuning fork to calculate sound velocity in air.

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!

Create clear sound shakers so your preschooler can observe and compare the different sounds that objects make!

Try this goofy, first grade phonics craft that focuses on the letter "F" as in "Frog" and helps build crucial reading and spelling skills in your child.

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.

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

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 experiment is to identify common materials that absorb sound waves with the greatest efficiency.

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

Determine the relationship between the speed of a sound and the temperature of the air it passes through.

Use a digital camera and some simple drawing supplies to help your kindergartener make a personalized letter-sound book.

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

This classic children's game demonstrates how sound travels through air vs. through a solid.

This classic children's game-connecting two cups with a string-demonstrates sound's ability to travel through air vs through a solid.

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

Learn about how we localize objects and beings in space through sound and about monaural auditory mechanisms and binaural auditory mechanisms.

In this sound experiment children listen for differences as they tap on a bag of air, a bag of water, and a wooden block held up to their ears.

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

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.

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

Play hopscotch with numbers, but also with letters, to get kids ready for reading.

This science fair project idea shows how a vibrating object transfers energy to whatever it touches.

The goal of this science fair project is to evaluate the effect of heat on sound wave frequency.

This experiment will explore how mallets of various materials and weight create sonic tones of varying lengths.

Is your child learning to "sound it out"? This game will help him stretch his "decoding" skills so when he runs into new words, he's ready to take them on.
