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.

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 investigate how some butterfly wings get their color.

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

In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity, learners cut out and fold their own collapsible origami starshade, an invention that shields a telescope's camera lens from the light of a distant star so that NASA scientists can ex

In this activity (posted on March 14, 2011), learners follow the steps to construct a camera projector to explore lenses and refraction.

In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.

Learners build a solar oven from a cardboard pizza box, aluminum foil and plastic. Learners can use their oven to cook S'mores or other food in the sun.

In this activity, learners discover that nanoparticles of gold can appear red, orange or even blue. They learn that a material can act differently when it’s nanometer-sized.
