Will storing cucumbers and tomatoes in the fridge destroy their unique flavors? Find out in this science fair project idea!

Discover that the absorbency of fabrics depend largely on the shape and structure of the individual fibers that make up the fabric.

This science fair project teaches you about what makes persimmons so tart and how astringency can be removed by studying the effect of tannins on fruit.

This science experiment tests if dog saliva can really help heal wounds.

Learn how to make a hygrometer to measure relative humidity in this project. Make a sling psychrometer hygrometer with gauze, thermometers, and a bottle.

Students explore hot desert plant adaptations in this cool science fair project by observing how these organisms prevent excessive transpiration.

The rock cycle will come alive for your child when he uses broken crayons to create the three basic rock types.

Kids will learn about insulation, heat conduction, and the economic benefits of energy efficient windows in this cool science fair project.

This science fair project idea examines the distance a person travels on an average day and to relate that to an understanding of the size of the Earth.

Prove that the Earth is not flat. The objective of this science fair project is to measure the angle of the sun and calculate the circumference of the Earth.

Science fair project which compares the rate of temperature change and the maximum temperature as a result of the angle of light radiation.

In this outdoor science activity you'll find tips on how to create a nature journal by choosing a native plant or animal and tracking that species.

Wind is an important source of renewable, green energy. The purpose of this science fair project is to build and operate a windmill generator.

Kids will conduct a cool limewater carbon dioxide test that can be performed with common household materials to learn about the chemistry of this common gas.

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

In this fun experiment, we'll find out how color affects heat absorption!

This science fair project idea investigates if heat from direct sunlight is hotter than heat from reflected sunlight.

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

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.

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

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

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

This science fair project idea explores whether cats can be trained in the same way that dogs can.

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.

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

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.

Construct and experiment with a periscope using reflected light rays to gather an image.

This science fair project idea examines whether the colors of the spectrum respond differently in the thermal aspect when radiated by the sun.
