Show your kids the power of baking powder by conducting a simple experiment. Make four batches of cornbread, all identical except for one thing: baking powder!

Here's a fun math and science activity: help your child explore four different kinds of measurement, using their hand and a few simple household tools.

Here is a hands-on activity to help third graders understand the four points of a compass...and how we use them to get around.

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

Marshmallows are made of sugar, water, and air pockets. Since the marshmallow is flexible, will air pressure cause it to expand when heated in a microwave?

Science fair project examining barometric pressure, and how it can be used to predict the weather. How does atmospheric pressures relate to weather conditions?

Help your fifth grader execute this experiment involving a lit candle (submerged in water!) to show him the wonders of heat energy transference.

The project investigates how friction affects motion by using different surface textures.

What is elasticity? Students will investigate how this concept applies to bouncing ball physics by testing the bounces of balls made out of different materials.

These science fair experiments demonstrate the chemistry of rust and the oxidation process.

Your third grader will be amazed at the explosive combination of vinegar and baking soda in these chocolate volcano cupcakes with white chocolate "lava."
