From the Genetic Science Learning Center at the University of Utah comes this collection of educational resources about the use of models in scientific research and communication. These resources, which include illustrated essays, videos, and interactive activities, help learners understand how scientists can use models to understand natural phenomena and create public policy. Science instructors may be interested in using these materials to supplement existing curriculum. This collection is divided into three sections. The first two sections, Models and What you can do with models, are designed to help learners broadly understand the role of models in earth science. In the third section, Modeling water in the West, learners are invited to consider an authentic scenario: water allocation in the American West. One highlight of this section is a series of four online simulations, which invites learners to manage a watershed in four types of communities: suburban sprawl, agricultural, low impact development, and industrial city types.
