Pbs Learning Media: How Disruptions Affect Animal Populations

Young scholars explore the effects that ecosystem disruptions can have on animal populations. They learn about the disruptions that have driven three species-the Madagascar fish eagle, the Iberian lynx, and the rowi kiwi, to the brink of extinction.They also discover the impacts that a shift in the population of one animal can have on others in an ecosystem. As a final assignment, students use evidence they've gathered from media, text, and other lesson elements and produce an essay or visual model.
