Crater Counting Lab exercise part of Rates and Time:Teaching Activities
Kevin Mullins, Coconino County Community College
This lab is designed to teach students how we can estimate the age of other planetary surfaces by counting and size-binning impact craters. It also illustrates some examples of how erosional or deopositional ...

The Cosmic Calendar part of Rates and Time:Teaching Activities
Erika Grundstrom, Vanderbilt University
In this activity, one takes ALL of time, from the beginning of time (i.e., the Big Bang) all the way up to today, but one compresses it into one year. One can do this for all levels of students depending on how ...

Peritectic Phase Diagram part of Petrology:Teaching Examples
Dexter Perkins, University of North Dakota-Main Campus
An exercise to help students figure out what is going on with peritectic phase diagrams. It is NOT trivial.

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 ...

Stoke's Law Problem Set part of Sedimentary Geology:Sedimentology, Geomorphology, and Paleontology 2014:Activities
Rachel Headley, Albertson College of Idaho
This is a problem set that involves the calculation of velocities from a Reynolds number, determination of Stoke's Law applicability, and calculation of settling velocities for a variety of grain sizes and ...

Aeolian Processes part of Sedimentary Geology:Sedimentology, Geomorphology, and Paleontology 2014:Activities
Alec Aitken, University of Saskatchewan
This activity explores the environmental variables that influence wind erosion. Key words: aeolian, fluid threshold, impact threshold,sedeiment entrainment and transport, particle size analysis

Stream Morphometry, Stream Flow, Stream Competence part of Sedimentary Geology:Sedimentology, Geomorphology, and Paleontology 2014:Activities
Alec Aitken, University of Saskatchewan
This exercise combines field activities (i.e., topographic survey of a point bar; sediment sampling with a soil auger), laboratory analysis (i.e., particle size analysis of fluvial sediments), topographic map ...

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 ...
