Lesson: Exothermic and Endothermic Reactions Chemistry • 7th Grade

Start Practising

In this lesson, we will learn how to describe exothermic and endothermic reactions and examine the energy transfers involved.

Lesson Plan

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.
