Learn how to construct a light box by following simple figures and instructions. This guide includes tips on how to assemble a light box; related activities are featured in separate resources.

In this activity, learners make prisms from gelatin. Learners then shine light through the prisms and discover what happens. This activity introduces learners to the idea of refraction.

In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

In this activity, learners create night lights using a plastic cup, programmable PICO Cricket, tri-color LED, and sensor.

Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.

In this activity, learners use an old CD to construct a spectroscope, a device that separates light into its component colors.

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 explore how nanosized structures can create brilliant color.

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

In this activity, learners investigate how some butterfly wings get their color.

Put on a pair of gloves and be the conductor of your invisible orchestra!

Use a Pico Cricket (micro-controller) to animate your art! You can program a Pico Cricket to make your art spin, light up, or make music.

Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

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 (posted on March 20, 2011), learners follow the steps to construct a stroboscope, a device that exploits the persistence of vision to make moving objects appear slow or stationary.

In this activity, learners investigate the properties of graphene and graphite.

This is a web page that helps informal educators brainstorm on how to use a Pico Cricket (tiny computer) in an informal activity.

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

In this activity, learners create a colorful bookmark using a super thin layer of nail polish on water. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity, learners explore the many uses of periscopes and how this simple device was designed and is used in many applications.
