In this activity, learners use an old CD to construct a spectroscope, a device that separates light into its component colors.

This is a quick activity/demonstration that introduces learners to the concept of index of refraction. Learners place stirring rods in a jar of water and notice they can see them clearly.

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.

Learners test their "light-smarts" by playing a game called "Light Quest!" The game board represents an atom and each player represents an electron that has been bumped into the atom's outer unstable
