Lesson Plan: Exothermic and Endothermic Reactions Chemistry • 7th Grade
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to describe exothermic and endothermic reactions and examine the energy transfers involved.
Objectives
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.
Prerequisites
Students should already be familiar with
- energy changes in reactions,
- units of energy,
- solids, liquids, and gases and the conversion between them.
Exclusions
Students will not cover
- measuring enthalpy changes,
- reaction profiles,
- calculating the enthalpy change of a reaction or bond energies.
