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

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.

This science experiment tests why guacamole goes brown and if leaving the pit in will stop guacamole from turning brown.

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 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.

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.

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.

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

Work on homophones, words that sound the same, and spelling with this imaginative activity!

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.

This homemade snare drum made with everyday household items gets its authentic rattle sound from paper clips and tin.

Okay, engaging in a graphing activity may sound ho-hum, but if you use fun data, it changes the picture entirely.

"Crown" dad this Father's Day—and sneak in some letter-sound practice, too.

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

Strong writing engages all five senses, and this fabulous fall-themed simile activity is the perfect way to celebrate sight, sound, smell, taste, and touch.

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 activity, your child will take a walk outside, listen to the silence in between sounds, and draw what the experience was like for them.

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

Encourage your child to take in the tastes, smells, sights, sounds and textures of the year's spookiest holiday with a sensory poem!

Transfer your child's artwork onto clothing using an iron-on transfer. It's easier than it sounds, and your child will love wearing his artwork!

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

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