Unit 5: Growth and Decay of Ice Sheets part of Modeling Earth Systems
David Bice, Pennsylvania State University-Main Campus
Large continental ice sheets, such as the Laurentide Ice Sheet from the last glaciation, as well as Antarctica and Greenland of today, are some of the most important features of the global climate system — they ...

Unit 6: Hydrologic Balance and Climate Change part of Modeling Earth Systems
Kirsten Menking, Vassar College
In this unit, students create a STELLA model of the Owens River chain of lakes in eastern California and then experiment with different climate change scenarios to simulate the Pleistocene history of lake filling ...

Unit 7: Heat Flow in Permafrost part of Modeling Earth Systems
Kirsten Menking, Vassar College
In this unit, students create a STELLA model of heat flow in the top 1 km of Earth's crust to explore the use of Arctic borehole temperature profiles as recorders of anthropogenic warming. The exercise draws ...

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 ...

Unit 3: Simple Climate Models part of Modeling Earth Systems
Louisa Bradtmiller, Macalester College
Students will explore Earth's radiation budget using several versions of a simple climate model often referred to as a "layer model." Earth receives energy from the sun, some of which is reflected ...

Unit 8: Thermohaline Circulation part of Modeling Earth Systems
David Bice, Pennsylvania State University-Main Campus
In this module, students first review some background material on density-driven deep currents in the oceans, and then create a STELLA model of the thermohaline circulation in the North Atlantic Ocean. The model ...

Unit 9: Carbon Cycle and Ocean Chemistry part of Modeling Earth Systems
David Bice, Pennsylvania State University-Main Campus
In this module, students first review some background material on the terrestrial, marine, and anthropogenic processes involved in the storage and transfer of carbon in the Earth system. The students then build a ...

Summative Assessment: Creating a model part of Modeling Earth Systems
Kirsten Menking, Vassar College; Louisa Bradtmiller, Macalester College; David Bice, Pennsylvania State University-Main Campus
The summative assessment for this course requires students to construct, utilize, and critique a numerical model of a climate-related Earth system of their choosing. The project involves four pieces: creating a ...

Unit 3: Managing the Risks of Lead Exposure part of Lead in the Environment
Katrina Korfmacher (University of Rochester), Richard Gragg (Florida A&M), Martha Richmond (Suffolk University), and Caryl Waggett (Allegheny College)
In the past two units, students considered the strengths and limitations of scientific tools to identify exposure pathways and demographic patterns of lead poisoning. In Unit 3, students evaluate domestic ...

Unit 1: Introduction to Flooding part of Flood Hazards
Venkatesh Merwade, Purdue University (vmerwade@purdue.edu) James McNamara, Boise State University (jmcnamar@boisestate.edu)
Do geoscientists understand the meaning of floods and their role within the broader context of ecological and societal impacts? In this unit, students are introduced to the concept of flooding and the mechanisms ...
