This activity was designed for blind learners, but all types of learners can use it to investigate how different materials vary in their conduction of heat.

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.

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.

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, learners explore liquid crystal thermometers to observe how heat flows by conduction, convection, radiation, and evaporation.

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 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.
