In this optics activity, learners work in pairs to explore how mirrors work. Learners use tape to mark the angles needed to see each other's reflection in a wall mirror.

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

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

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

In this activity about light and perception, learners create pictures in thin air.

In this optics activity, learners experiment with polarizers (small dark rectangles) to examine light intensity.

Learners use two mirrors to explore how images of images of images can repeat forever.

This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.

In this activity, learners use gelatin as a lens to investigate the properties of laser light.

In this optics activity, learners use a shoebox, colored cellophane and sunlight to "change" the colors of gumballs. Learners will be surprised when the green and blue gumballs appear black!
