IS2500 Endothermic Reactions
When chemical reactions absorb heat the environment around the reaction becomes colder. Students will create an endothermic reaction and monitor the change in temperature as the reaction occurs. Students will then examine a commercial application that exploits endothermic reactions, the instant cold pack. The kit contains enough materials for 15 groups. Teacher’s Manual and Student Study Guide copymasters are included.
