Writing chemical reactions part of Cutting Edge:Geochemistry:Activities
John Ayers, Vanderbilt University
This is a simple introduction to writing weathering and redox reactions by hand and by using the Rxn program in the Geochemists Workbench. Its usually the first HW assignment I give in my class "Geochemical ...
Mineral Solubility Calculations part of Cutting Edge:Geochemistry:Activities
John Ayers, Vanderbilt University
Explores the pH dependence of the solubility of quartz, kaolinite, and rare earth phosphate, and familiarizes students with the use of the Geochemists Workbench programs "React" for creating reaction path ...
Temperature/Salinity/Density activity part of Cutting Edge:Introductory Courses:Activities
Petra Dekens, San Francisco State University
This is an in-class activity designed to improve the students' understanding of the relationships between temperature and density, salinity and density, and density differences in driving vertical water ...
Acid Mine Drainage Field-Lab Experience Round 1 part of Cutting Edge:Geochemistry:Activities
Greg Druschel, University of Vermont and State Agricultural College
This contribution outlines a trip with my Geochemistry class to the Ely Mine, a massive sulfide mine (Besshi-type) in east-central Vermont and the field work they did there. We spent a full day discussing the site, ...
Relationship between mineral weathering and groundwater composition part of Cutting Edge:Geochemistry:Activities
Nancy Hinman, University of Montana-Missoula, The
By observing changes in rocks exposed to chemical weathering, students are to infer resulting changes to the chemical composition of groundwater. Students are required to justify their inferences through the use of ...
Spreadsheet analysis of chemical hydrographs part of Cutting Edge:Hydrogeology:Activities
This is a good activity to have students practice spreadsheet analysis skills on a medium large data set. It also helps them understand stream hydrographs and baseflow/quickflow components.
Timing of mineralization in the palm of your hand: Cross-cutting relations, copper minerals and ore-forming hydrothermal fluid evolution part of Cutting Edge:Courses:Petrology:Teaching Examples
Barb Dutrow, Louisiana State University
This lab is designed to familiarize students with the geologic history of an ore-deposit, deciphered in the palm of your hand. By determining cross cutting relations of veins and mineralogy, students decipher the ...

Using spring water chemistry to understand groundwater inputs part of Cutting Edge:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
Rebecca Frus, University of New Mexico-Main Campus
The assignment will begin with teaching proper water collection and use of equipment for hydrochemical field work. Once the class is familiar with sample collecting technques, the class takes a field trip to ...
Living Learning Community: Spaceship Earth Research Course part of Cutting Edge:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
Penelope Boston, New Mexico Institute of Mining and Technology
Freshmen enrolled in the Spaceship Earth Living Learning Community conduct research on a real project that is formulated and conducted during a 2-semester academic year.
Environmental Geochemistry poster project part of Cutting Edge:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
Jodi Ryder, Central Michigan University
This is an independent case study project completed in pairs. The students should investigate an example of natural geochemistry and then use a poster format to share their findings with the class.
How acidic is the rain if atmospheric CO2 concentration doubles? part of Cutting Edge:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
Lixin Jin, University of Texas at El Paso, The
Students use basic aqueous geochemistry knowledge to investigate controls of the atmospheric carbon dioxide level on pH values of the wet precipitation at standard conditions (25 oC, 1 atmospheric pressure).
Dilutions and Spectral Properties of Solutions part of Cutting Edge:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
Carmen Nezat, Eastern Washington University
The purpose of this week's lab is to - prepare calibration standards - use a UV-Vis spectrometer to determine the spectral peaks for several dye solutions, and create a calibration curve - calculate how much ...
Spatial and Temporal Tracer Test Data Analysis part of Cutting Edge:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
Kenneth Carroll, New Mexico State University-Main Campus
This is an assignment I worked on with Dr. Brusseau (University of Arizona) for his Contaminant Transport class. In this problem solving exercise, students are provided data sets that could be obtained by ...
Batch and Rayleigh Decarbonation Modeling of d13C part of Cutting Edge:Courses:Petrology:Teaching Examples
Jade Star Lackey, Pomona College;
