Modeling Exsolution (and Perthite Formation) as an Example of Complex-System Behavior part of Cutting Edge:Complex Systems:Teaching Activities
Dave Mogk, Montana State University-Bozeman; Barb Dutrow, Louisiana State University
Students use a physical model, computer simulation, examples from the natural world, visualizations, and overarching thought experiments to explore this phenomenon. Exsolution embodies attributes of a complex ...

Modeling U-Series Concordia/Discordia Using STELLA part of Rates and Time:GSA Activity Posters
Kirsten Menking, Vassar College
U-Series dating techniques are widely used to determine the absolute ages of some of Earth's oldest rocks, but the concordia/discordia diagram can be quite difficult for students to grasp. I have produced a STELLA-based lab exercise to develop students' understanding of this important chronologic technique. Students create models of the two isotopic decay systems and run these models to create the concordia diagram. They then carry out experiments in which they "add" or "remove" varying amounts of lead or uranium in simulation of metamorphism. In the course of the lab, students are introduced to the concepts of exponential decay and secular equilibrium as well as modeling concepts such as the creation of if-then statements.

Introduction to Equilibrium Thermodynamics: Salt Dissolution part of Activities
Andrew Knudsen, Lawrence University;
Students dissolve simple salts, halite and sylvite, in water at different temperatures and explore the thermodynamics of this simple system to build a foundation for further studies.

Variation Diagrams and the Evolution of Thingmuli Lavas, Iceland part of Cutting Edge:Petrology:Teaching Examples
Jeff Tepper, University of Puget Sound
In this problem set students are provided with an EXCEL spreadsheet containing major element analyses of lavas frm Thingmuli Volcano in Iceland. They are asked to construct variation diagrams (Harker plots) and ...

Zoned Plagioclase Exercise part of Cutting Edge:Petrology:Teaching Examples

Pet Rock Project: A Semester-long Exercise for Igneous and Metamorphic Petrology part of Cutting Edge:Petrology:Teaching Examples
Darrell Henry, Louisiana State University
The pet rock project is a semester-long project in which each student randomly selects an igneous or metamorphic rock from the instructor or brings in a rock from an appropriate locality, and follows all of the ...

Graphing Chemical Data to Identify Fractional Crystallization part of Cutting Edge:Petrology:Teaching Examples
John Brady, Smith College
Students are given major-element, whole-rock chemical analyses from ten samples of lava from the 1868 eruption of Mauna Loa. They do not know sequence of eruption, only that the lavas came from the same volcano. ...
