Lesson: Energy Changes in Reactions Chemistry • First Year of Secondary School

In this lesson, we will learn how to identify types of energy and relate changes in energy to chemical bonding and chemical reactions.

Lesson Plan

Students will be able to

define different types of energy, with an emphasis on chemical, thermal, and light energy,
understand the concept of a system and the surroundings and how the transfer of heat between them occurs during a chemical reaction,
identify and describe the different types of systems: open, closed, and isolated,
understand that in chemical reactions, energy is both required and released, but the overall change in energy is important,
understand that the plimsoll notation refers to standard conditions and define what these conditions are,
Identify that the overall change in energy during a reaction is known as the enthalpy change and has the symbol .
