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.

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

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.

This engaging project encourages young children to practice and refine the important scientific skills of sorting and classification.

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.

Sorting objects by size, color, shape, or function is an important concept in kindergarten math, and it's the perfect excuse for a little housekeeping!

Help your child learn science and math skills like sorting, sequencing, and ordering while taking a nature walk and collecting and collaging leaves.

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.

Delay your child's sugar overload, and develop his critical thinking skills, by doing some "sweet sorting" of his Halloween treasures!

Help your child reinforce the order of the alphabet with this hands-on activity using some everyday materials. It's a fun way to put a spin on a timeless skill.

This science project teaches students the relationship between compost and plant growth. Students conduct an experiment with different types of compost.

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.

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.

Build up those kindergarten letter-sound reading skills...and create a whimsical, practical craft at the same time.

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.
