A Quantitative Visualization of Mantle Melting part of Pedagogy in Action:Library:Spatial Reasoning with GeoClick Questions:Examples
Hannah Shamloo, Oregon State University
Here is an exercise to acquaint students with pressure-temperature diagrams related to Earth's interior, teach why the mantle melts in the context of pressure and temperature, demonstrate the role water has on melting, and review the three ways to melt the mantle.

Collection of PT Phase diagram exercises part of Teaching Examples
Dexter Perkins, University of North Dakota-Main Campus

Metamorphic Facies CogSketch geoscience worksheet part of Introductory Courses:Activities
Bridget Garnier
Sketching activity that uses a sketch-understanding program, CogSketch. Students plot pressure and temperature points from metamorphic environments (i.e. subduction zone and continental convergence) onto the ...

Calculating Pressures and Temperatures of Petrologic Events: Geothermobarometry part of Teaching Examples
Donna Whitney, University of Minnesota-Twin Cities
In this lab exercise, students examine one or more metamorphic rocks and use various approaches to estimating and calculating the pressure-temperature conditions at which the rocks equilibrated. The exercise ...

Progressive metamorphism of pelitic rocks: A lab assignment to facilitate translation from AFM space to P-T space part of Teaching Examples
Jane Selverstone, University of New Mexico-Main Campus
This is an example of a lab activity aimed at teaching students how to go from natural samples to AFM diagrams to P-T conditions of equilibration.

Calculating Compositional Variation and Common Substitutions for Igneous and Metamorphic Minerals part of Teaching Examples
Dave Mogk, Montana State University-Bozeman

In this problem set the students use two different equations to calculate a conductive geothermal gradient using a spreadsheet program like Excel. Once they have the geothermal gradient plotted, they are asked to ...

Learning Thermodynamics and Using Spreadsheets part of Teaching Examples
Sumit Chakraborty and Somnath Dasgupta
These files contain a set of three Excel files to balance mineral reactions, to explore variation of thermodynamic properties as a function of P, T and composition and to explore stability of different mineral ...

Pet Rock Project: A Semester-long Exercise for Igneous and Metamorphic Petrology part of 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 ...

Thermobarometry Problem Set part of Teaching Examples
Jane Selverstone
This homework assignment gives students first-hand experience with thermobarometric calculations. Because many of my students are math challenged, I give them a choice of solving the equations by hand or with ...

Binary eutectic in-class exercise (Di-An) part of Teaching Examples
Allen Glazner
