This unit explores nine of the main systems of the body. Children learn the purpose of each body system, what the main organs of the system are and their specific functions, and how the organs work together in order for the system and body to function as a whole. This 68-page unit includes lesson extensions designed for students Grades 7–8. The Human Body Part 2, which will be released at a future date, will cover the topics of genetics and illness and disease, and it will take a closer look at some of the different types of cells within the body.
