Freeze distillation of hard apple cider: A phase diagram demonstration part of Teaching Activities
William Peck, Colgate University
If you are lucky enough to teach Petrology in a part of the world with a cold winter, freeze distillation of hard apple cider works well as a class demonstration when the cider is frozen overnight outside. The slow ...

Collection of PT Phase diagram exercises part of Petrology:Teaching Examples
Dexter Perkins, University of North Dakota-Main Campus
I am always needing more phase diagrams exercises so my students can practice problem solving. This collection includes 5 different exercises that can be used for homework, in-class, or for quizzes or exams.

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 ...

The use of visualization and sketches of thin sections to encourage a better understanding of phase diagrams: Binary and ternary phase diagram exercises part of Petrology:Teaching Examples
Jennifer M. Wenner and Drew S. Coleman
In these homework exercises, students manipulate two- and three- component phase diagrams. At various points during their interpretation of melting or crystallization of a composition, they are asked to ...

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 ...

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 ...

T-X Phase Diagrams part of Petrology:Teaching Examples
Dexter Perkins, University of North Dakota-Main Campus
This is a 15 page tutorial and problem set designed to get students familiar with T-X diagrams, their implications, and uses.

Atmospheric Vertical Structure and the First Law of Thermodynamics part of Quantitative Skills:Activity Collection
Anthony Hansen, Saint Cloud State University
This set of homework problems is intended to help students begin to discover the importance and utility of conservation principles derived from the First Law of Thermodynamics and provide a first step in evolving from the p-V diagrams the students have seen in their physics coursework toward the thermodynamic diagrams used in meteorology.
