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

Make two firefly lanterns, then program them to blink to one another and change colors.

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.

This activity generates learner excitement about light through the creation of a room-sized rainbow.

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.

This activity models the way Landsat satellites use a thermal infrared sensor to measure land surface temperatures.

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