In this lesson, students make observations of external and internal parts of trees in order to collect evidence that these structures work together as a system to help plants survive in a particular environment. In the activity, Tree Detective, students use models of roots and branches to explore their functions and then construct an argument about how these structures must work together in order to support the survival of trees in the unique environment of the frozen taiga.
