In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.

In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).

In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.

In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.

In this activity, learners explore conservation of energy by experimenting with a solar cell light device.
