This is a inquiry-driven class research project on a local environmental geochemistry question that is accomplished during three-hour laboratory sessions each week. Students are divided into groups that will share the responsibilities of collecting samples and data. Once the data is collected, it is shared among the entire class so that all students have the same data set. The class works on data presentation, preliminary analysis, and statistics together Then each student writes his/her own report separately. Outcomes: 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.
