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

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

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 quiz lets you estimate your annual radiation exposure.

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 activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.
