Put your young paleontologist's puzzle-solving skills to the test by having her hunt for dinosaur bones and then assemble them to create dinosaur skeletons.

Science fair project that compares the freezing temperature of salt water and freshwater in order to learn about supercooling and condensation nuclei.

This science project has students study a group of volunteer liars actively lying to study the behavior of a lie. Students see if they can figure out the truth.

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.

Kids will learn about the interaction of lactose and lactase in milk and discover why we describe enzymes as catalysts in this fun science fair project.

This science fair project idea examines which type of insulation holds in the most heat.

Have your kid determine if a goldfish can be conditioned to expect food the same way Pavlov's dogs did with this fascinating science fair project.

This science fair project focuses on the use of the enzyme amylase found in human saliva to break down starch into sugar.

Help your child create a working lung model that fills with air just like the lungs inside of his own chest when he breathes.

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