Determining Mantle Temperature and Composition from Discontinuities part of Deep Earth:Activities
Anna Courtier, University of Wisconsin-Madison
This pair of activities uses observations of mantle discontinuity structure to examine mantle heterogeneity and differences in the depth extent of melt sources for ridges and "hotspots." The first ...

Modeling Exsolution (and Perthite Formation) as an Example of Complex-System Behavior part of 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 ...

Chemistry of Cave Formation part of Introductory Courses:Activities
Carol Ormand Ph.D., Carleton College
Students investigate what happens to calcium carbonate in an aqueous solution when the pH of the water changes.

Marine Oxygen Isotopes and Changes in Global Ice Volume part of Climate Change:Activities
Ben Laabs, North Dakota State University-Main Campus
Students explore marine oxygen-isotope data from cores collected by the Ocean Drilling Program. The activity gives students access to real paleoclimate data, develops their skills in organizing and graphing data, ...

Working with Electron Microprobe Data from a High Pressure Experiment - Calculating Mineral Formulas, Unit Cell Content, and Geothermometry part of Petrology:Teaching Examples
Brandon Schwab, Western Carolina University
In this problem set students use electron microprobe analyses of a peridotite partial melting experiment to determine mineral formulas, calculate unit cell content, plot results on a classification diagram, and use ...

Extending Mineralogy by Electron Microprobe Analysis part of Petrology:Teaching Examples
John Goodge, University of Minnesota-Duluth
This lab is designed to be a highly interactive lab session for a petrology course, where instructors provide a minimal level of essential background and then the entire group works together to explore mineral ...

Calculating a Simple Phase Diagram: Diamond=Graphite part of Petrology:Teaching Examples
Dexter Perkins, University of North Dakota-Main Campus
This is a very short exercise designed to get students to understand how the Gibbs energy equation is used to calculate the location of a reaction in P-T space. I use it in-class and have students work on it in ...

Problem set: Constructing metamorphic phase diagrams using phase equilibria and the Clausius-Clapeyron equation part of Petrology:Teaching Examples
, Smith College
In this problem set students construct a P-T phase diagram for the aluminosilicate polymorphs based on experimental phase equilibria and application of the Clausius-Clapeyron equation. The problem set uses unit ...

Periodic Table of the Elements Activity part of Geochemistry:Activities
Laura Wetzel, Eckerd College
Students work in groups to create the Periodic Table of the Elements in class using cards that they completed as homework. This is meant as a review of the Periodic Table and a direct illustration of how Dmitri ...

Calculating Compositional Variation and Common Substitutions for Igneous and Metamorphic Minerals part of Petrology:Teaching Examples
Dave Mogk, Montana State University-Bozeman
This problem set uses Excel spreadsheets to calculate mineral formulae from analytical data (typically from the electron microprobe) using a variety of formulations that assume numerous variations of crystal ...
