Geologic Time Calculations
Francisco San Juan, Elizabeth City State University
Radiometric age determination using parent/daughter composition and a radiometric decay curve.
Calculating the radius of the Earth
Basil Tikoff, UW Madison
Science students often have difficulty thinking about large spatial scales. The purpose of the exercise is to redo Eratosthenes' calculation of the radius of the Earth using data from to sites in ancient Egypt. The excercise teaches about the methodology of science - how Eratothenes figured it out - rather than worried about what the "right" answer is. It can also be used to discuss the role of models in geological thinking.
Understanding Radioactivity in Geology: The Basics of Decay
Christina Stringer—University of South Florida, Tampa FL 33620 This activity was developed for Spreadsheets Across the Curriculum . National Science Foundation, DUE 0442629.
PowerPoint module leading students through creation and manipulation of spreadsheet to forward model an example of exponential decay—the number of remaining unpopped kernels of popcorn in a bag of popping popcorn.
Humans as Geomorphic Agents
Catherine Riihimaki, Princeton University
An introduction to order-of-magnitude calculations and reading quantitative journal articles.
Jeff Wilson, University of Texas at Brownsville, The
Learning about the different ways the morphological variation can be coded into phylogenetic character data, with emphasis on the limitations and assumptions of each.
The science behind Plate Tectonics
John Weber, Grand Valley State University
Plate tectonics is a quantitative, robust and testable, geologic model describing the surface motions of Earth's outer skin. It is based on real data and assumptions, and built using the scientific method. New ...
Soil Properties and Geomorphology
Mark Sweeney, University of South Dakota
Compare soil data to different ages of fluvial terraces. Students enter data into Excel and interpret it themselves.
Tom Hickson, University of St. Thomas (MN)
Students examine 3D channel-shaped objects and 2D slices through those objects. The purpose is to get them thinking about how the 3D geometry of a channel is reduced to a random 2D slice through the channel in a typical outcrop, so that they can recognize channel deposits.
