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.
Batch and Rayleigh Decarbonation Modeling of d13C part of Cutting Edge:Courses:Petrology:Teaching Examples
Jade Star Lackey, Pomona College;
This is an Excel spreadsheet and graph that illustrates standard "batch" and Rayleigh decarbonation models and how they can be used to detect fluid infiltration during metamorphism of carbonates. It makes ...
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.
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 ...
Copper Extraction Demonstration Tutorial part of Starting Point-Teaching Entry Level Geoscience:Interactive Lecture Demonstrations:Examples
Summary This demonstration uses sulfuric acid and crushed copper ore (malachite) to produce a solution of copper sulfate and carbonic acid in a beaker. When a freshly sanded nail is dropped into the copper sulfate ...
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.
Integrating research methods into geochemistry using local resources part of Cutting Edge:Geochemistry:Activities
Jeanette Jerz, DePauw University
This is a semester-long project that introduces students to research methods and practices. Students learn both field and lab techniques and how to develop testable hypotheses. Using local resources is an easy way ...
Using Data to Teach Earth ProcessesAn Illustrated Community Discussion at the 2003 Annual Meeting of the Geological Society of America part of Cutting Edge:Data, Simulations and Models:Workshop 03:Activities
Rachel O'Brien, Allegheny College
Rachel O'Brien Department of Geology, Allegheny College - This is a first-year college course on water and N cycling that involves four active-learning projects utilizing datasets collected by the students ...
