In this activity, learners make their own pinhole viewer in order to measure the size of the sun.

Did you know that using a lens one can bend light to make pictures of the world? It's true!

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

In this activity, learners explore light, color and rainbows by making their own rainbow glasses.

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.

Have fun with additive mixing! Observe what happens when the three primary colors of light--red, green and blue--are mixed together, resulting in white light.

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).

This is an activity exploring color and color mixing.

In this optics activity, learners build a spy tool to secretly view things over walls or around corners.

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

Learners experiment to see which colors of light will cause a phosphorescent (glow-in-the-dark) material to glow.

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.

In this optics activity, learners discover that when they rotate a special black and white pattern called a Benham's Disk, it produces the illusion of colored rings.

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

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.
