Learners observe and conduct experiments demonstrating the different properties of hot and cold materials.

This three-part activity consists of an activity that groups of learners develop themselves, a given procedure, and an optional demonstration.

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 explore how light and dark colored objects absorb the Sun's radiations at different rates.

Learners investigate how the temperature of water affects its density.
