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

Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

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 on page 2 of the PDF, learners test different materials to find out which is the best insulator.

Conduct a simple experiment to explore how temperature changes can make things expand or contract.

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