G08: Sciences Chemistry: Reactions

This video explores the energy implications of chemical change. It can be used to supplement the investigation Exothermic, Endothermic, & Chemical Change or may stand on its own to introduce a lesson or extend student learning.

Exothermic reactions transfer energy to the surroundings and the temperature of the surroundings increases. Endothermic reactions take in energy and the temperature of the surroundings decreases.

In order for a chemical reaction to occur, the particles, atoms or ions — which are reactants — must physically come into contact with one another. It’s WAY more interesting than it sounds. Trust us
