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 ...
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).
Analysis of Hydrochemical Data part of Cutting Edge:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
Joseph Asante, Oberlin College
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 ...
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 ...
Geochemistry all around us part of 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 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 ...
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.
Introduction to urban watershed geochemistry part of Cutting Edge: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 ...
Weak Acid Equilibrium part of Cutting Edge: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 ...
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 ...
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 ...
