In this Beacon unit plan, students begin to understand who they are by first analyzing their genetics, and second, by taking a closer look into their cells and how these cells interact within the body. The students are formatively assessed throughout the unit in order to guide instruction and assess student understanding of the material. Finally, the students create a What Makes Me Who I Am picture book in which they explain to younger children the information they have discovered which makes them who they are. Created picture books are then shared with other students from lower grades.
