In this activity, learners construct wands that play different notes depending on information from light sensors programmed via a PICO Cricket.

In this activity, learners use their strength to light a light bulb. A chain made from paper clips is placed in series with a battery and flashlight bulb.

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 Jell-O to explore lenses. Learners cut Jell-O into convex and concave lens shapes and examine how light exits each lens in a darkened room.

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 explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.

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 how nanosized structures can create brilliant color.

In this activity, learners use UV light to transfer a pattern onto a plastic board. The pattern is transferred by placing a mask (a transparency sheet with the pattern) on a plastic board.

In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.

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.

In this activity, learners test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.

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

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

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.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.
