In this project students determine which instruments composers use to create birdsongs and birdcalls in classical music.

Find out whether matching resonant frequencies can cause objects to shatter.

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.

This project determines what percentage of test subjects react adversely to the sound of fingernails on a chalkboard and explores their physiological responses.

This simple "how to make a water wheel" activity makes physics come alive for your child by demonstrating how different kinds of energy work.

How do series and parallel circuits work, and which produces the brightest light in a light bulb? Construct both in this project and find out!

Kids will conduct a cool limewater carbon dioxide test that can be performed with common household materials to learn about the chemistry of this common gas.

This activity will help your child review science concepts, learn new ones, and become familiar with examples of various concepts in science. Plus, it's fun!

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

Make stunning pendulum waves and learn the math behind the patterns generated with this cool and easy science project.
