In this science fair project, young children notice and track changes in trees throughout the year.

In this activity, children will work on their mathematics and engineering skills as they attempt to recreate the Eiffel Tower out of building blocks!

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

Do this experiment to help your first grader understand how salt can be removed from salt water. All it takes are a few household materials.

Kids grow sunflower greens from seeds for a hands-on gardening experience in this kindergarten life science activity.

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

This science fair project focuses on a polymer called hydrogel super absorbent crystal which absorbs water, swelling to many times its original size.

Young scientists will investigate people's preferences for saltiness, and make some inferences about genetics and diet.

This simple experiment serves as an introduction to the greenhouse effect.

In this activity, your child will make her own "quicksand" to better understand how a substance can be both fluid and solid at the same time.

In first grade, children are introduced to fractions. Here's a recipe that combines fraction practice with winter fun and lets kids actually paint the snow!

It's food. It's Thanksgiving tradition. And guess what: Cranberry Sauce is also science! Try our simple recipe/experiment.

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.

Help your child create a garden journal sketchbook as she observes and records the natural world through the changing seasons.

Will the shape of an ice cube impact how fast the ice melts?

In this project, a mnemonic is used to test how it increases memory.

This science fair project idea determines if crystals will absorb food dye and if colors will mix by the process of diffusion.

Construct batteries that make electricity from fruits with this fun science fair project.

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

How does a flashlight work? Kids will make a complete circuit and explore how voltage contributes to brightness with this science fair project idea.

How does the size of a vibrating surface affect the pitch of a drum? Learn about drum size and pitch with this easy science fair project idea.

In this windmill model science project, you will build a windmill to learn about wheel-and-axle machines and how these simple machines are used to do work.

Science fair project in which you will attempt to throw a ball the greatest horizontal distance possible by using different angles.

Do you have your isopods straight? Learn about sow bug and pill bug behavior by building a terrarium to study them in!

Is it amplitude? Weight? Length of string? Kids will discover what factors changing the period of a pendulum depends on in this fun and easy physics experiment.

Science fair project which determines whether it is numerically possible to be connected to every person on the earth within six degrees of separation.

This science fair idea examines hydrogel superabsorbent polymer crystals. They can absorb 500 times their weight in water. Can they absorb other liquids too?

Learn how different types of soil affect how animal tracks form in this experiment!

Science fair project which simulates the global conveyor belts on a small scale, and observes the effects of wind, density and temperature on water movement.

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