Measuring Distance and Area in Satellite Images
LuAnn Dahlman
DATA: MODIS Imagery. TOOL: ImageJ. SUMMARY: Examine images of the Aral Sea from 1973 through 2003. Use image analysis software to measure changes in the width and area of the freshwater lake over time.

Jurassic Park Debate
Rebecca Teed, Wright State University-Main Campus
This role-playing exercise casts students as scientific specialists, assigned to a group either supporting or opposing the cloning of dinosaurs. Each group researches and presents its argument. -

Wheel of Geology
Rebecca Teed, Wright State University-Main Campus
This quiz game is intended to help students review for an upcoming exam. Topics of questions are randomly determined by spinning a wheel. Teams answer questions using electronic CPS handhelds. -

Fossil Identification Board Game
Robert L. Reuss and Anne F. Gardulski (Tufts University)
The instructor uses a series of games to help students identify and answer questions about fossils. The game grows more complex over time as the instructors add rules and phyla to identify. -

Using Melting Ice to Teach Radiometric Decay
Developed by Donald Wise, Franklin and Marshall College. Taken from Wise, 1990 . Related Links Radioactive Decay
Students are challenged to a Sherlock Holmes-style mystery in which they construct their own decay curves of melting ice to determine time-zero.

Demonstration of radioactive decay using pennies
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.

Using Popcorn to Simulate Radioactive Decay
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
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).
