Environmental Geochemistry Class Project
This activity was selected for the On the Cutting Edge Exemplary Teaching Collection
Resources in this top level collection a) must have scored Exemplary or Very Good in all five review categories, and must also rate as “Exemplary” in at least three of the five categories. The five categories included in the peer review process are
- Scientific Accuracy
- Alignment of Learning Goals, Activities, and Assessments
- Pedagogic Effectiveness
- Robustness (usability and dependability of all components)
- Completeness of the ActivitySheet web page
For more information about the peer review process itself, please see http://serc.carleton.edu/NAGTWorkshops/review.html.

Laboratory skills -- Students have basic laboratory skills necessary to carry out a supervised geochemical study (e.g. can perform Gram titration of waters in field, can collect water samples using clean methods).
Quantitative methods -- Students can manipulate, sort, and transfer data in Excel and can create simple x-y plots and histograms to bring out trends in data.
Critical thinking -- Students can develop multiple hypotheses to explain trends in data and can design tests of these hypotheses.
Skills and concepts that students must have mastered
