This science fair project idea investigates the difference in reaction times between boys and girls.

In this science fair project, apply the principles of leverage and force by building six simple machines designed to set weights in motion.

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

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.

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