You know that the human body is a wonderful system of interrelationships, but have you wondered just how your body works? Through various activities, students learn that cells are the basic unit of life. Cells work together to form tissue. Tissues work together to form organs. Organs work together to form systems. The various parts and functions of our body systems are unveiled as students learn the relationships between our systems and how these relationships keeps us alive and well. Reading in the content area and study skills such as note taking, outlining, graphic organizers, and illustrating are learned as students gather and organize facts about the human body. Although the overall size of the unit appears overwhelming, a user friendly routine is quickly established. This routine allows for progression to higher order thinking skills while remaining student and teacher friendly as the unit is taught.
