Ecosystems STEM Case

As a national park ranger, students must restore the ecosystem of a park back to normal. They interact with populations of many organisms including wolves, deer and bees. Students learn the importance of food chains and webs, and how human factors can impact the health of an environment.

STEM Cases are interactive explorations in which students practice problem-solving and critical thinking as they solve a real world problem as a STEM professional. More About STEM Cases
