Unit 5: Growth and Decay of Ice Sheets part of Modeling Earth Systems
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
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 ...

Unit 4: The Magic of Geophysical Inversion part of IGUaNA:Teaching Materials:Evaluating the Health of an Urban Wetland Using Electrical Resistivity
This unit introduces the student to the concept of geophysical inversion, which is the process of estimating the geophysical properties of the subsurface from the geophysical observations. The basic mechanics of ...

Module 9: Climate Change part of Future of Food
Module 9 is dedicated to climate change and explores the role that agriculture plays in human-induced climate change and the impacts that climate change may have on agriculture. In addition, adaptation strategies ...

Unit 2: Geophysical Properties of the Subsurface part of IGUaNA:Teaching Materials:Evaluating the Health of an Urban Wetland Using Electrical Resistivity
Archie (1950) defined the term petrophysics to describe the study of the physics of rocks, particularly with respect to the fluids they contain. Although originally focused on geophysical exploration, petrophysics ...

Unit 1: Introduction to Modeling Dynamic Systems part of Modeling Earth Systems
In this unit we introduce students to the reasons why Earth and environmental scientists use numerical modeling as a tool for understanding complex systems and then teach them how to use the STELLA software that ...

Unit 4: Daisyworld part of Modeling Earth Systems
Students explore Daisyworld, a model of a self-regulating system incorporating positive and negative feedbacks. Daisyworld is a planet on which black and white daisies are the only things growing. The model ...

Unit 10: Coupled Economic and Environmental Models part of Modeling Earth Systems
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 ...

Wind and Ocean Ecosystems part of Project EDDIE:Teaching Materials:Modules
Wind has a fundamental impact on ocean ecosystems. Wind drives physical processes, including current development and upwelling through Ekman transport. These physical processes, in turn, have cascading impacts on ...

Unit 5: Mitigating future disasters: developing a mass-wasting hazard map part of Surface Process Hazards
This unit serves as the summative assessment of the Surface Process Hazards module. In September 2013, the Boulder area of Colorado experienced an extreme rain event that led to mass wasting in many areas. This has ...

Unit 2: Global Sea-Level Response to Temperature Changes: Temperature and Altimetry Data part of Understanding Our Changing Climate
