Curated OER
Endothermic or Exothermic That Is the Question
Students conduct an experiment to determine what happens to heat energy during a chemical reaction. They examine an endothermic reaction by observing a chemical reactions.

Heat Loss and Gain in Physical Changes and Chemical Reactions
Students compare and contrast exothermic and endothermic reactions. In this chemistry lesson, students perform experiments to determine whether heat was released or absorbed in a reaction. They share their observations in class.
