Every day our body carries on a myriad of activities.  Some are volitional (we choose them). Many more occur without our knowledge or input.

"It" is defined as any project created by students.  It could be a model that is built, a book report that is written, or an activity conducted in a gymnasium, or on stage.  This project explores the way the human body systems do what they do.  The lessons introduce students to the shared and integrated responsibilities carried out by our bodies every day.  The project begins with the level of the organism, proceeding to the organ systems, then to organs, then to tissues, and finally to cells.  The objective is for students to see the similarities in form and function and the efficient way in which life activities are carried out.
