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

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

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.

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

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 four-part activity, learners explore light and sound through a variety of hands-on investigations.

In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.
