In this fun optics activity, learners explore principles of light, reflection (mirrors), and perception. Learners work in pairs and sit on opposite sides of a "two-way" mirror.

In this activity, learners explore how nanosized structures can create brilliant color.

In this activity, learners explore the invisible infrared radiation from an electric heater.

In this activity, learners explore the relative efficiency of different bulbs, specifically incandescent vs. fluorescent.

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

In this physics activity, learners recreate Galileo's famous experiment, in which he dropped a heavy weight and a light weight from the top of the Leaning Tower of Pisa to show that both weights fall
