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.

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.

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.

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.

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.

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.
