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.

Who knows you may even make a new scientific discovery of your own and get to wear your hair like Albert Einstein.

Easy Activities

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

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

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.

Activity of the Moment

Total Internal Reflection

When light hits an interface between two different media, it can behave in two different ways. Typically, the light partially refracts (bends) and partially reflects. The refractive index of the material is what determines how fast light travels in a material. Light travels about one and a third times faster in air than in water. Learn about total internal reflection in this activity.
