2018 revision

This learning activity has been entirely revised, although the same principles are covered. The first four sections of the revised Student Handout focus on understanding two phenomena: food poisoning and recovery of endangered species (e.g. whooping cranes). To understand these phenomena, students develop and investigate the exponential and logistic population growth models. Then, students investigate why these population growth models cannot account for many observed population trends, e.g. the decline in whooping crane populations that resulted in their endangered status. In a new final section, students apply what they have learned to a brief analysis of human population growth.
