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.

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.

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!

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

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

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

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.

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.

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.

Find out whether we can create motion in a dish and as a result, create a wonderful and colorful show.

Make over an old shirt that's destined for the thrift shop with this heart cut-out craft for Valentine's Day.

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

Here's a fun activity to show your child how to use prefixes and root words to "root out" the meaning of a word!

Stay active over summer vacation with this fun take on the old favorite Red Rover!

This activity teaches your third grader how to make a paper cut-out still life, in true Matisse-style.

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.

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.

Filling out forms can be a great learning experience for kids. Here's how to give your child some FORMal training.

The project determines which laundry detergent is best for cleaning clothes.
