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

This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

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 (1st on the page), learners find their blind spot--the area on the retina without receptors that respond to light.

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

In this activity, learners will make homemade jello that glows under a blacklight. They will learn about quinine, an ingredient in tonic water that is fluorescent.

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

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

In this optics activity, demonstrate diffraction using a candle or a small bright flashlight bulb and a slide made with two pencils.

In this activity, learners examine how colored lenses act like filters and absorb all colors of light except for the color of the lenses.

This activity provides instructions for building a mirrored tube--a smaller and simpler version of a submarine's periscope--that lets you see around corners and over walls.

In this optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.

In this activity, learners make their own heat waves in an aquarium.

In this activity, learners will create their own simple shadow puppets, and experiment with light and shadow while playing with them.

In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

In this optics activity, learners discover how they can make glass objects "disappear." Learners submerge glass objects like stirring rods into a beaker of Wesson™ oil to explore how the principles of

In this activity, learners overlap the three primary colors to see how all other colors are made.

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

In this demonstration, amaze learners by performing simple tricks using mirrors. These tricks take advantage of how a mirror can reflect your right side so it appears to be your left side.

In this optics activity, learners split white light into all its component colors using three household items: a compact disc, dishwashing liquid, and a hose (outside).
