This project examines Newton's First and Second Laws of Motion with a bicycle and water balloons.

This science project examines the history of earthquakes and what we can do to prevent future disasters.

The objective of this experiment is to identify common materials that absorb sound waves with the greatest efficiency.

This exploration of different types of energy will help young minds appreciate and observe thermal, kinetic, mechanical, and other forms of energy.

This classic children's game-connecting two cups with a string-demonstrates sound's ability to travel through air vs through a solid.

This project demonstrates the correspondence between the volume of water displaced by a submerged object and the volume of the object displacing it.

Find out the differences (if any) in the frequencies of voices produced from a computer, from a phone, and directly coming out of the voice box of a human.

Observe how your brain works while it is focused on one thing, and how it works while you are distracted by another thing.

Demonstrate how we are able to locate sounds, echolocation. Have a blindfolded subject locate you by the sound of your clapping.

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.

This kids' activity is fun to perform and impressive to watch. Plus, it's a great example of Newton's First Law of Motion at work.

Help your kindergarten scientist discover relative size, density, and buoyancy with this fun, pumpkin science project!

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.

Put your second grade scientist to work this Fourth of July with our colorful "liquid fireworks" project!

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.

Look for a correlation between temperature and the intensity of cricket chirping. Measure ambient temperature and sound intensity in decibels.

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