Science fair project that demonstrates how a rainbow forms, by using water to split white light into its many colors.

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.

Check out this cool science fair project idea to learn why it is important for kids to eat healthy foods like fresh fruits and vegetables.

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

The objective of this science project is to determine the length of time for different seeds to germinate.

How do animals keep warm? In this experiment, find out whether fat insulation resists cold temperatures and learn how this works in the animal kingdom.

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 examines whether ocean water can be made safe to drink.

Here is a kindergarten activity that blends art and science by using magnets, paint, and objects found around the house to create a picture.

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

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