This unit is about the basics of the human body in anatomy. Each lesson goes over certain parts of the body and what these parts functions are. The big idea in this unit is learning about your body and what it consists of. Many students know that their body is made up of different materials but they do not know what everything is called and how it works together. This unit consists of going over and teaching about the skeletal and muscular systems and tendons and ligaments. With each lesson, they build off of each other. The students started from the shell and worked their way up, building layers on top of the shell.
