The objective of this science fair project idea is to examine light refraction as it passes through liquid crystals.

Invite your fifth grader to test the different rates of liquid absorption in synthetic and cotton materials, such as nylon and cotton.

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

Discover which fabrics shrink the most in the wash and why.

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 cool project, create a lighted, scale model of the different layers of the Sun, including the core, radiation and convection zones, and photosphere.
