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

Challenge popular misconceptions, learners explore how a mirror actually reflects an image in this activity.

In this trick, hold your hand over a burning candle without getting burned, by reflecting and transmitting the light of two candles. This activity is best suited as a demonstration.

In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.

In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.

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 use gelatin as a lens to investigate the properties of laser light.

In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.
