Modeling the carbon cycle of the anthropocene part of Activity Collection
Students use an Excel sheet to complete forward and inverse models of changes in carbon distribution between atmosphere, ocean and the biosphere from 1751 to the present and several centuries into the future. The model is given as a mostly complete package, into which students input emissions data in various sensitivity tests.

An Assessment of Hillslope Stability Using the Factor of Safety part of Activity Collection
In this homework assignment students are asked to consider the balance of forces on a hill slope using the Factor of Safety.

Kohler Curves part of Activity Collection
An assignment teaching students about Kohler curves that enhances their quantitative skills.

Using a Mass Balance Model to Understand Carbon Dioxide and its Connection to Global Warming part of Activity Collection
Students explore the increase in atmospheric carbon dioxide over the past 40 years with an interactive on-line model.

Estimating Primary Production in the Oceans from Satellite Data part of Teaching Methods:Teaching with Data:Examples

How Does Surface Deformation at an Active Volcano Relate to Pressure and Volume Change in the Magma Chamber? part of Teaching Methods:Teaching with SSAC:Examples
SSAC Physical Volcanology module. Students build a spreadsheet to examine and apply the Mogi model for horizontal and vertical surface displacement vs. depth and pressure conditions in the magma chamber.

Porosity and Permeability of Magmas part of Teaching Methods:Teaching with SSAC:Examples
SSAC Physical Volcanology module. Students build a spreadsheet for an iterative calculation to find volume of bubbles and hence porosity, permeability and gas escape as a function of depth.

How Do We Estimate Magma Viscosity? part of Teaching Methods:Teaching with SSAC:Examples
SSAC Physical Volcanology module. Students build a spreadsheet to examine how magma viscosity varies with temperature, fraction of crystals, and water content using the non-Arrhenian VFT model.

Carbon Sequestration in Campus Trees part of Teaching Methods:Teaching with SSAC:Examples
Spreadsheets Across the Curriculum module. Students use allometric relationships to calculate tree mass from trunk diameter in a stand of trees in the Pacific Northwest.

Chemical Equilibrium Misconceptions part of Teaching Methods:Mathematical and Statistical Models:Examples
This STELLA modeling and writing assignment helps students confront and replace common misconceptions about chemical equilibrium.
