In this optics activity, learners use water to make a coin "appear" and "disappear." Use this activity to demonstrate how light refracts and introduce light as waves.

In this optics activity, learners explore how light bends and affects what we see.

In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

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.

This activity (located on page 3 of the PDF under GPS: Light and Color Activity) is a full inquiry investigation into mixing colors with light.

In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.

In this four-part activity, learners will discover the exciting world of light--the most important form of energy in our world--and be able to identify and describe different types of light.

In this activity, learners use gelatin as a lens to investigate the properties of laser light.

In this optics activity, learners make a "light fountain" from a clear plastic bottle, flashlight, and other simple materials.

In this activity, learners use transparent tape and polarizing material to create and project beautifully colored patterns reminiscent of abstract or geometric stained glass windows--no glass required

In this activity, learners discover what happens when they crush wintergreen-flavored candies in a very dark room.

In this optics activity, learners make a lens and explore how the eye manipulates the light that enters it.

In this activity, learners create a water prism to break light into the seven colors of the rainbow.

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.

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

In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).

In this activity, learners explore why the sky is blue. Learners model the scattering of light by the atmosphere, which creates the blue sky and red sunset, using a flashlight and clear glue sticks.

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 investigate the reflective properties of light and mirrors as they make a kaleidoscope.
