This science fair project idea determines if the temperature of rubber effects how high it bounces.

Learn about lateral earthquake motion and its effect on high rise buildings in this simple 4th grade earth science experiment.

This is a fantastic and easy science experiment where kids will learn about elasticity by testing how high bouncy balls of different materials can bounce.

In this project, you'll build a model of the earth, complete with all seven continents and four major oceans.

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

This science fair project idea produces varying pitches of sound.

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

Discover whether different amounts of water added into a wine glass will produce a different pitch when their fingers are rubbed along the rim.

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?

In this pinto bean germination experiment, you'll learn about how fertilizer aids in growing pinto beans into seedlings.

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.

Science fair project that teaches you about chemical indicators and how to make your own in order to identify various mystery solutions.

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

Examine which metal conducts more heat by boiling water in 3 pans made of aluminum, copper, and stainless steel.

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

Is your child a young ornithologist in the making?

Will potatoes spud or sprout faster in dry, dark, or cold conditions? Find out in this science fair project idea!

Have you ever noticed the way a dropped stone makes a fun pattern in a pond or lake? What's the science behind these splashy occurrences?

This science fair idea project identifies the active ingredients in soap and experiments with the properties of soap.

To help your child learn how to use a thermometer, try this temperature collecting activity at home.

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

This science fair project idea explores substances that cause a bubble to last longer.

This science fair project on testing water hardness is a great introduction to practical chemistry. Test and learn the difference between hard and soft water.

This project explores whether plants can live and grow when "watered" with juice, soda, or milk.

In this experiment, kids will see if pruning tomato plants makes them more fruitful and learn about the factors that contribute to a plant's fruit production.

What are the effects of fertilizer on plant growth? What's the best fertilizer type (solid, liquid or powder)? Kids find out in this science fair project idea.
