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

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 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 activity (on page 2 of the PDF under SciGirls Activity: Doghouse Design) is a full inquiry investigation into absorption and reflection of radiant energy.

This quiz lets you estimate your annual radiation exposure.

Get a roll of pennies, throw them on the ground, then remove those that only show tails, and repeat with the ones left over.

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 explore how light and dark colored objects absorb the Sun's radiations at different rates.

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

Use this hands-on activity to demonstrate infrared and thermal radiation.

In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.
