Unit 10: Coupled Economic and Environmental Models part of Modeling Earth Systems
Louisa Bradtmiller, Macalester College
How do people treat commonly held resources? Ecologist Garrett Hardin suggested that, in the absence of any restrictions or incentives, rational people will tend to drastically overuse any common resource. In this ...

Unit 2: Modeling Population part of Modeling Earth Systems
Kirsten Menking, Vassar College; David Bice, Pennsylvania State University-Main Campus
In this unit, students create three different STELLA models to explore a variety of concepts related to population growth and resource use. The first model simulates the classic lynx-snowshoe hare predator-prey ...
