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

Learners design their own experiment to investigate whether the temperature of the surrounding water affects the rate at which the colored coating dissolves from an M&M.

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

In this activity, learners explore the process of condensation.

Learners add calcium chloride to a baking soda solution and observe an increase in temperature along with the production of a gas and a white precipitate. These are all signs of a chemical reaction.
