Lesson: Exothermic and Endothermic Reactions Chemistry • 7th Grade

Students will be able to

• define what exothermic and endothermic reactions are and how they differ,
• identify whether a reaction is exothermic or endothermic from the sign of the energy change and experiments,
• suggest how and why exothermic and endothermic reactions could be used in various applications,
• determine whether changes between different states of matter (e.g., melting) are exothermic or endothermic processes.
