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.

In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.
