In this lesson, you'll concentrate on the driving force that exists in both chemistry and physics—the drive for equilibrium. You'll start by reviewing some basic principles of chemistry, including the structure and behavior of atoms, ions, and molecules. Then, the lesson will cover states of matter and the differences between their shape, volume, structure, molecular movement, and energy level. By the end of the lesson, you'll have a good understanding of thermal, mechanical, and chemical equilibrium and you'll know how to teach those concepts to your students. As a bonus, the lesson will also include some fun activities you can share with your students that they'll really enjoy.
