This module presents a “game” activity in which students learn about trophic cascades and how the different elements of a food chain interact. The module explores the importance of top-down regulation and how predators may regulate the habitats in which they live.
In this module, students learn: 1) How predators and prey interact, 2) How human activities may disrupt ecosystem integrity, 3) How to formulate predictions and hypotheses, 4) How to engage in argument from evidence, make and interpret simple graphs, and make estimates based on data they collect.
