Understanding Radioactivity in Geology: The Basics of Decay part of Quantitative Skills:Activity Collection
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.

GEOLogic: The Big Five Mass Extinctions part of Quantitative Skills:Activity Collection
Laura Guertin, Penn State Brandywine
Students are asked to match up the five largest mass extinction events with their relative dates, approximate duration, and severity (percentage of species that became extinct) based on clues given from various perspectives.

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.

GEOLogic: Lagerstatten and Unique Fossils part of Quantitative Skills:Activity Collection
Laura Guertin, Penn State Brandywine
Students are asked to match up several unique fossils with the site and location where it was found and it's geologic age.

Quantitative Classroom Exercises part of Quantitative Skills:Activity Collection
Steven Schafersman, The University of Texas of the Permian Basin
The four exercises give students an opportunity to use their knowledge of graphs, algebra, and maps to solve simple geological problems.

Using Popcorn to Simulate Radioactive Decay part of Quantitative Skills:Activity Collection
Jennifer Wenner, University of Wisconsin-Oshkosh
Popping popcorn in your class is an excellent way to illustrate both the spontaneity and irreversible change associated with radioactive decay. It helps students to understand the unpredictability of decay.

M&M Model for Radioactive Decay part of Quantitative Skills:Activity Collection
Jennifer Wenner, University of Wisconsin-Oshkosh
A tasty in-class demonstration of radioactive decay using two colors of M&M's. Illustrates the quantitative concepts of probability and exponential decay. This activity is appropriate for small classes (<40 students).

GEOLogic: Dinosaur Trackways part of Quantitative Skills:Activity Collection
Laura Guertin, Penn State Brandywine
Students must associate different dinosaur trackways with their locations and the rock formations containing the trackways based on clues given from various points of view.
