This lab is designed to meet the Ecosystems: Interactions, Energy, and Dynamics NGSS HS-LS2-1 standard. In the lab, students will use mathematical representations to support explanations of factors that affect carrying capacity of ecosystems. Students will graph and analyze given data of the Arizona Kaibab deer population between the years of 1905 and 1939. Students will then assess effectiveness of strategies and the impact on many interdependent factors. Lab includes a lab introduction and lab analysis rubric, graph rubric, and conclusion rubric.
