In this activity, learners explore what happens when polarized white light passes through a sugar solution.

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

Learners demonstrate how water can distort, refract and magnify light.

In this activity, learners explore phosphorescence and how certain materials can absorb and store energy from a light source.

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

In this activity, learners explore the invisible infrared radiation from an electric heater.

In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.

In this activity, learners explore why they can see colors in bubbles and why they change.

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

This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.

In this activity, learners explore how and why rainbows form by creating rainbows in a variety of ways using simple materials. Learners create rainbows indoors and outdoors.

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

This is an activity (located on page 3 of the PDF under Stained Glass Activity) about nanotechnology making its way into everyday products, such as sunscreen, and how effective these invisible particl

In this activity, learners actually feel the difference in energy required to light two different types of light bulbs: incandescent light and LEDs.

In this activity, learners construct their own spectroscope as they explore and observe spectra from familiar light sources.

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

In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.

In this activity, learners work in groups of four to explore light. Learners create new colors from the primary colors of light from flashlights covered in theatrical gels or cellophane.
