This activity will introduce your child to the four different components of blood and give him a fun way to visualize its properties.

Science fair project which examines the relationship between frequency of spider web vibration and spider's response time.

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.

Here's a fun at-home activity that will help your child strengthen math skills using high and low temperature data, and become a master temperature tracker!

In this science fair project, young children will become aware of and have the opportunity to experience the four basic tastes: sweet, sour, salty, and bitter.

Kindergarten algebra is a lot different than high school. In kindergarten math, algebra means grouping like things, or noticing what doesn't belong in a set.

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.

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.

The purpose of this science fair project is to build a basic radio.

Science fair project which measures whether tsunamis are more destructive when they are caused by an earthquake or by a meteor.

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?

This homemade parachute toy is incredibly easy to build. Plus, it gives kids an excuse to investigate and experiment...the backbone of kindergarten science.

This activity is a fun way for your first grader to learn about how veggies help your body while being creative with art and drama. Here's how to get started.

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.
