In this section you will find experiments that will help you understand the physics of light impress your friends with your new ability to manipulate light and color using nothing but a few gumballs and a shoebox.   Best of all, you will probably get to make a big mess all in the name of science.

Easy Activities
(Ages 5+)

These experiments explore the basic concepts of light and color. They will help you understand how light travels and how color and light interact with each other to produce amazing results. Activities in this section are suitable for scientists five and older.

Medium Activities
(Ages 10+)

Light bends when traveling through various substances, can be scattered depending on what it hits, and the colors white and black are not as simple as black and white. The experiments in this section are recommended for scientists 10 and older.

Advanced Activities
(Ages 15+)

You are ready to take it to the next level. You have mastered all the other experiments and need a challenge. Try your hand at these experiments, recommended for scientists 15 and above.

Hands-On Activities

Hands-On Optics (HOO) is an education program that brings together optics experts, teachers and parents to enlighten students about science, technology and the field of optics.

Activity of the Moment
