Investigate how to keep your fruit fresh for longer. The purpose of this science experiment it to determine which kind of bag best preserves fruit.

Science fair project which determines whether the size or the thickness of a piece of paper has an effect on how many times it can be folded in half.

In this experiment, you will be making your own paper flashlight by conducting electricty with graphite.

Boiling water in a paper cup is possible because of convection and the thermal properties of water and paper. Learn how with this fun science fair project idea.

In this free science fair project idea, we learn about surface tension and how it can support mass—in this case, a floating paper clip.

This easy and inexpensive paper towel science project introduces kids to important physical concepts like cohesion, adhesion, and capillarity.

This project compares the strength of one, two, and three-ply toilet paper.

This science fair project uses paper chromatography to investigate whether black, brown, orange, and purple are pure colors or mixtures of other colors.

Discover which absorbent material is the best; the Shamwow, paper towels, or cotton towels.

Science fair project that measures the relative times it takes a plastic bag and a biodegradable plastic bag to decompose.

In this sound experiment children listen for differences as they tap on a bag of air, a bag of water, and a wooden block held up to their ears.

The objective this science fair project is to determine whether a bigger bag will allow a homemade hot air balloon to fly higher than smaller bag.
