Chemistry, Physics and Geology
Exploring Cation Exchange Capacity through the use of the Soil Survey part of Cutting Edge:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
This assignment allows students to utilize real soil data/information presented online to learn how the some of the physical properties of the soil influence the chemistry of the soil and health of the ecosystem.
Construction of a Simple Conceptual Model part of Cutting Edge:Hydrogeology:Hydrogeology, Soils, Geochemistry 2013:Activities
This homework assignment is designed to give the students practice in developing a simple conceptual model using reservoirs, fluxes, and simple calculations of sediment, carbon and nutrient accumulation in a typical reservoir/river system. This assignment is typically used after an introductory lecture to biogeochemical cycles and gives the students a concrete example of nutrient and sediment issues in surface water systems.
