How powerful is the reaction between baking soda and vinegar? Find out here!

Is it solid or liquid? Create oobleck and witness the amazingly weird oscillation between the two!

Teach your first grade scientist the difference between liquids and solids using maple syrup.

This science fair project idea explores the relationship between oil and water in terms of density as well as hydrophilic/hydrophobic compounds.

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

In this physics project, learn about the relationship between light intensity and distance using a laser pointer, flashlight, and graph paper!

First grade science often covers solids, liquids, and gases. This silly science explores serious facts about the difference between all three.

Here's a fun activity that will introduce your fourth grader to the concept of frictionless motion by constructing a hovercraft.

In this 3rd grade science activity, you'll experiment with the little-known fourth state of matter: polymers! Mix borax with white glue and watch what happens.

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?

Learn with makes water molecules work with this fun and easy science activity!

Teach your kids about entropy with this fun, easy exercise, and teach your money to dance while you're at it!

By using static electricity generated from their body, a child can cause a small fluorescent lamp bulb to light up!

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!

Help your child understand surface tension by showing them how they can create a "skin" on top of water.

Every time a sound is produced it emits a sound wave. This experiment demonstrates how sound travels, using nothing more than a spoon and a string!

Want to make Halloween truly eerie? Science to the rescue! These ghouly hands come alive with a little help from simple chemistry.

This trick uses vertical and horizontal forces to help your child to push apart your hands apart, no matter how hard you try to keep them together!

This is a fun way to introduce kids to the concept of volume, and give them a quick hands-on activity to boot.

Engineers in training can get started with this simple wheel-and-axle construction activity.

If your science savy third grader is up for a challenge, let her bend light with a casserole dish!

How do people move pianos and heavy furniture into tall buildings? Show your kids some pulley potential with this simple household exercise!

This 4th of July, explore fourth grade science and make some safe fireworks in your own backyard using soda pop!

Students pit the heat capacity of water against the heat capacity of oil while looking at the effects of dipole rotation in this cool science fair project idea.

Children combine an acid and an alkaline substance to simulate a volcano eruption in this fun experiment.

This classic children's game demonstrates how sound travels through air vs. through a solid.

This fun marbled paper craft uses things you're likely to have around your house, and it teaches kids some simple chemistry too!

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

This homemade barometer allows your little scientist to contemplate and compare different air and weather conditions.

What's cooler than an explosion? Not much! This simple science experiment lets kids build their own pop rocket. So put on your safety goggles and let her rip.
