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.

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

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.

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.

Take a closer look at your furry friend (or the furry friend of a neighbor -- with permission) to discover if communication exists between cats and humans.

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

In this activity, your child will hear a story and practice mindful breathing. They will paint a picture that reminds them to bring mindfulness and kindness to their puppy mind.

Our breath can be a helpful tool to connect with a sense of peace and calm. In this home activity, your child will practice counting breaths, hear poems about nature and mindfulness, and write their own poem.

Make a phonics paper egg to help your child build up his reading and writing skills.

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

How does the size of a vibrating surface affect the pitch of a drum? Learn about drum size and pitch with this easy science fair project idea.

Use a basic tape recorder and some favorite books to help your first grader read smoothly--and make someone's day in the process!

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.

Whatever the season, celebrate greenery and growth by helping your child study some delightful spring words.

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.

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

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

This project will help keep your child's thoughts in order as he creates stories from the beginning all the way through to the end.

It's rhyme time! With this science fair project idea, your child will find out which words can be considered easy rhyming words, and why.

Give your child a glimpse of how another set of students approach reading by teaching him how the blind use braille.

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.

This fun geometry game requires players to use measurement, find perimeter, and draw polygons. It's great for a fourth grade math student!

Using a toy race car kids create a visual model of the Doppler Effect.

Stories change as you retell them. The objective of this science fair project is to demonstrate how information gets interpreted, distorted and changed.

This biodiversity project examines the biodiversity in your own backyard.
