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 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 ...

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 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 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 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 ...

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 ...
