Unit 6: Hydrologic Balance and Climate Change part of Modeling Earth Systems
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
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
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
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
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
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
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
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 ...

Geoethics Case Study: The Keystone Pipeline--Energy, Jobs or Environment? part of GeoEthics:Activities
David Mogk and Andrew Thorson, Montana State University-Bozeman Summary The Keystone Pipeline is a complex project that raises important environmental, economic, and international policy issues. Tar sands from ...

Measuring Plate Motion with GPS: Iceland | Lessons on Plate Tectonics part of Geodesy:Activities
This lesson teaches middle and high school students to understand the architecture of GPS—from satellites to research quality stations on the ground. This is done with physical models and a presentation. Then students learn to interpret data for the station's position through time ("time series plots"). Students represent time series data as velocity vectors and add the vectors to create a total horizontal velocity vector. They apply their skills to discover that the Mid-Atlantic Ridge is rifting Iceland. They cement and expand their understanding of GPS data with an abstraction using cars and maps. Finally, they explore GPS vectors in the context of global plate tectonics.

6. Energy from and to the Earth part of Renewable Energy and Environmental Sustainability
This module compares the spatial availability of geothermal resources for heating and cooling and evaluates different ground exchange systems for practical application. The operation of enhanced geothermal systems ...

8. Efficiency and Conservation part of Renewable Energy and Environmental Sustainability
Household energy use accounts for a significant portion of the nation's energy use; therefore, an important aspect of energy conservation is having buildings that are energy efficient. In this activity, ...

Unit 4: The Magic of Geophysical Inversion part of IGUaNA:Teaching Materials:Evaluating the Health of an Urban Wetland Using Electrical Resistivity
