Investigating Earthquakes: GIS Mapping and Analysis (College Level)
Brian Welch
This is a college-level adaptation of a chapter from the Earth Exploration Toolbook. The students download global quake data over a time range and use GIS to interpret the tectonic context. -

Mid-level spreadsheeting and complex modeling of real-world scarp evolution
William Locke, Montana State University-Bozeman
This exercise is a second or familiarization exercise in spreadsheeting, but is also a mathematical model for slope evolution. It uses the concept of "erosivity" (generally, the relative ratio of driving and resisting forces) and slope angle to reshape an initial topography. Finally, it asks the students themselves to come up with a real-world situation worth modeling.

An Assessment of Hillslope Stability Using the Factor of Safety
Laura Moore, Oberlin College
In this homework assignment students are asked to consider the balance of forces on a hill slope using the Factor of Safety.

Using Excel to plot numerical and analytical forms of the diffusion equation
Anne Lightbody, UNH
This computer-based assignment forces students to compare and contrast integral and differential forms of the conservation of mass equation, as well as analytical and numerical approaches to solution. Students are ...

Comparing Carbon Calculators
Mark McCaffrey, National Center for Science Education
Carbon calculators, no matter how well intended as tools to help measure energy footprints, tend to be black boxes and can produce wildly different results, depending on the calculations used to weigh various ...

Roping Geologic Time
Randall Richardson, The University of Arizona
After having talked about the geologic time scale, I ask for two volunteers from the class to hold a rope that is 50 feet long. I say that one end is the beginning of the Earth (4.6 billion years ago), and the other is today. I then give out 16 clothes pins and ask various students to put a cloths pin on the 'time line' at various 'geologic events'. Throughout the activity I have a quiz going on where the students calculate percentages of Earth History for major geologic events, and compare it to their own ages. On their time scale, the dinosaurs died only about two 'months' ago! The exercise is very effective at letting them get a sense of how long geologic time is, and how 'recently' some major geologic events happened when you consider a time scale that is the age of the earth.

Where is that chunk of crust going?
Vince Cronin, Baylor University
I introduce students to GPS, frames of reference, and the permanent GPS stations in the EarthScope Plate Boundary Observatory (PBO) in class, and obtain near-real-time data for two stations from UNAVCO. We use ...
