Mid-level spreadsheeting and complex modeling of real-world scarp evolution part of Quantitative Skills:Activity Collection

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 part of Quantitative Skills:Activity Collection

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.

Comparing Carbon Calculators part of Starting Point-Teaching Entry Level Geoscience:Teaching with Data:Examples

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 ...

Accessing Streamflow Data via the Worldwide Web part of Cutting Edge:Geodesy:Activities

John Pitlick, University of Colorado at Boulder

The objectives of this exercise are to (a) use the worldwide web to access hydrologic data, and (b) compare precipitation/runoff characteristics in different regions of the USA.

Roping Geologic Time part of Rates and Time:GSA Activity Posters

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.

How Many Is A Million? part of Cutting Edge:Rates and Time:Visualizations with Teaching Notes
