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.

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