Relationship between mineral weathering and groundwater composition part of 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 ...

Compositional Diversity in Volcanic Suites part of Activities
Kent Ratajeski, University of Kentucky
In this exercise, students use geochemical data downloaded from the GEOROC database to explore the origins of compositional variation among volcanic rocks associated with the Yellowstone and Crater Lake calderas.

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.

Rayleigh fractionation visualization part of Cutting Edge:Climate Change:Activities
E. Christa Farmer, Hofstra University
