Learners conduct an experiment to determine the rate at which two materials, sand and water, heat up and cool down.

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.

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.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

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

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

Learners apply their knowledge of heat transfer to design two cans - one that will retain heat and one that will cool down quickly.

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.
