Calculating Rb-Sr Isochrons part of Cutting Edge:Courses:Petrology:Teaching Examples
Andy Barth, IUPUI
This is a spreadsheet that I use in petrology to walk students through calculating Rb-Sr isochrons and talking about isotope heterogeneity and sampling at various scales. The example exercise is the Tuolumne ...

Crystallization-Differentiation of Basaltic Magma part of Activities
Kent Ratajeski, University of Kentucky
In this exercise, students use geochemical data from volcanic glasses and minerals in lavas and drill cores from the solidified Kilauea Iki lava lake to learn about the petrologic processes related to the eruption ...

Graphing Chemical Data to Identify Fractional Crystallization part of Cutting Edge:Courses: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. ...

REE Modeling of Melting and Crystallization part of Activities
Mark Schmitz, Boise State University
This exercise is used in and out of class for exploring the use of trace elements to model melting and crystallization processes; it emphasizes quantitative skills and constructing numerical models.

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.

Stable Isotopes and M&Ms part of Cutting Edge:Courses:Oceanography:Activities
Roman de Jesus, SUNY at Stony Brook
Students are often confused by the concepts of stable isotope signatures and conventional notation. This activity is designed to introduce students to the del notation (isotopic signature), fractionation, and end ...

Soil Ecology Lab part of Cutting Edge:Courses:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
Becky Ball, Arizona State University at the West Campus
Students collect soil samples from places of interest around campus and run a series of basic soil analyses to make conclusions about how soil fertility relates to the biological community and human management.

An In-Class Demonstration and Activity Using the FCAEM Remotely Operable Electron Microprobe part of Activities
Jeffrey Ryan, University of South Florida
This activity takes advantage of the full remote operation capabilities of the electron microprobe system available through the Florida Center for Analytical Electron Microscopy (FCAEM) at Florida International ...

Crystal Structures as Geobarometers part of Cutting Edge:Courses:Mineralogy:Activities
Kent Ratajeski, University of Kentucky
In this exercise, designed for undergraduate igneous petrology or advanced mineralogy courses, students download a series of crystal structures from the American Mineralogist Crystal Structure Database to explore ...

Research Paper part of Cutting Edge:Early Career:Previous Workshops:Workshop 2010:Teaching Activities
Alan Wanamaker, Iowa State University
This writing assignment was a major part of a class entitled "Stable Isotopes in the Environment" at Iowa State University. The main goals of the assignment were to foster effective scientific writing and ...

Weak Acid Equilibrium part of Cutting Edge:Courses:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
Michael Stapleton, Slippery Rock University of Pennsylvania
Students are asked to calculate the pH of a weak acid aqueous solution. The problems involve a series of generic acids with assigned equilibrium constants (Ka) and total concentrations (Ct). Initially, students are ...

Analysis of Hydrochemical Data part of Cutting Edge:Courses:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
Joseph Asante, Tennessee Technological University
In this activity students examine groundwater flow path based on hydraulic head data/ potentiometric surface and spatial variation of groundwater chemistry. Students analyze the data using AquaChem and Phreeqc ...

Introduction to urban watershed geochemistry part of Cutting Edge:Courses:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
Vijay Vulava, College of Charleston
The main goal of this multi-part field and lab exercise is to introduce students to practical aspects of soil and water geochemistry. Some of the analyses for this lab are conducted in the field using field ...

Co-evolution of Life and Minerals part of Cutting Edge:Courses:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
Penelope Boston, New Mexico Institute of Mining and Technology
Based on the 2010 Scientific American paper by Hazen, and the more technical 2008 paper of Hazen et al, both of which explore the effect of the biosphere on the tremendous number of mineral species that occur on ...

Geochemistry all around us part of Cutting Edge:Geochemistry:Activities
Andrew Knudsen, Lawrence University
We look at a variety of natural waters in and around Appleton over the course of the term. The goal is for students to recognize differences and how those play into the topics we have covered in the course.
