Radioactive Decay and Geochronology part of Quantitative Skills:Activity Collection
Kirsten Menking, Vassar College
Students create a STELLA model of the radioactive decay process.

The Floating Lithosphere - Isostasy part of Quantitative Skills:Activity Collection
Len Vacher, University of South Florida
Students are asked to numerically and then analytically determine the relations governing the depth of compensation.

Applications of Vector Operators for Surface Atmospheric/Oceanic Processes part of Quantitative Skills:Activity Collection
David Smith, United States Naval Academy
This lab exercise provides students with activities utilizing vector operations within the context of the atmospheric and oceanic environments.

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.

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.

Viscosity of the Mantle: Constraints from Post-glacial Rebound part of Quantitative Skills:Activity Collection
David Kohlstedt, University of Minnesota-Duluth
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.

Driving Through Geologic Time - An analogy part of Quantitative Skills:Activity Collection
Eric Baer, Highline Community College
An analogy of the Earth's history to a cross-country drive.

Exploring Radiometric Dating with Dice part of Quantitative Skills:Activity Collection
Carla Whittington derived from Baer (1999) Related Links Radioactive Decay ProbabilityExponential Growth and Decay
An activity in which students use dice to explore radioactive decay and dating and make simple calculations.

Demonstration of radioactive decay using pennies part of Quantitative Skills:Activity Collection
Jennifer Wenner, University of Wisconsin-Oshkosh
A demonstration (with full class participation) to illustrate radioactive decay by flipping coins. Shows students visually the concepts of exponential decay, half-life and randomness. Works best in large classes -- the more people, the better.

Determining Earthquake Probability and Recurrence from Past Seismic Events part of Quantitative Skills:Activity Collection
Eric Baer, Highline Community College
A homework/classroom activity where students collect historical earthquake information and use it to forecast the probability of larger earthquakes.
