Three-Point Problem by Simultaneous Linear Equations part of Quantitative Skills:Activity Collection
William Frangos, James Madison University
Students are introduced to the use of linear algebra in an intuitive and accessible way, through classroom activity and homework set. The familiar three-point problem is cast in terms of three dimensional analytic geometry, fostering understanding of mathematical models for simple geometric forms.

Viscosity of the Mantle: Constraints from Post-glacial Rebound part of Quantitative Skills:Activity Collection
David Kohlstedt, University of Minnesota
This laboratory experiment emphasizes the exponential nature of post-glacial rebound and reinforces the relationship between the rate of rebound and the viscosity of the mantle.

Assessing the error of linear and planar field data using Fisher statistics part of Quantitative Skills:Activity Collection
Vince Cronin, Baylor University
Instruction on use of Fisher statistics to determine the mean and 95% confidence interval of geological vectors, lines or planes, with examples, problems and an Excel spreadsheet for computation.

Air-sea Interactions: Activities in Oceanography part of Quantitative Skills:Activity Collection
Steve LaDochy, California State University, Los Angeles
This online set of activities help students learn properties of ocean waves, wind-wave relationships and properties of tsunamis.

Weathering of Minerals part of Quantitative Skills:Activity Collection
Wendy Van Norden, harvard-westlake school
Students determine the % change in mass of mineral samples that have been placed in a rock tumbler. They graph the relationship between the hardness of the mineral and the % change in mass. They then consider why some of the mineral samples do not conform the the relationship they graphed. They investigate the physical properties of the outliers and consider how the physical properties contributed to the rate of weathering, and what kind of weathering occured in the rock tumbler.

My Special Place part of Quantitative Skills:Activity Collection
Sadredin Moosavi, Tulane University of Louisiana
Students pick a place of significance to them (their Special Place) for analysis in this semester-long project. (A model is provided by the instructor using a place the students are not likely to have visited.)

Laboratory Activity: The Sun and Climate part of Quantitative Skills:Activity Collection
Peter Selkin, University of Washington-Tacoma Campus
In this physical geography lab, students examine the relationship between solar altitude, solar declination, and temperature regimes. Using data collected in the field, mathematical relationships, and temperature records available on the Internet, students compare the insolation and climate in their location to that of other locations.

Geologic Time Calculations part of Quantitative Skills:Activity Collection
Francisco San Juan, Elizabeth City State University
Radiometric age determination using parent/daughter composition and a radiometric decay curve.

Reading Topographic Maps and Calculating Map Scale part of Quantitative Skills:Activity Collection
Leslie Kanat, Johnson State College
Use a topographic map to deliniate a watershed, draw a map bar scale, and calculate a map ratio scale.

Understanding Radioactivity in Geology: The Basics of Decay part of Quantitative Skills:Activity Collection
Christina StringerUniversity 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 decaythe number of remaining unpopped kernels of popcorn in a bag of popping popcorn.
