To understand the root of, and potential solutions to many environmental problems requires knowledge of environmental geochemistry’s fundamental components (e.g., acid-base, redox, and precipitation-dissolution reactions). However, environmental geochemistry is currently taught in a way that emphasizes quantitative skills to understand these chemical systems without application to real-world problems that an environmental geochemistry background can play a role in solving. This project will audit and refocus the curriculum of GEOL366 Sedimentary Petrography and Geochemistry to build foundational skills which students can then apply to ongoing real-world environmental problems and assess their possible solutions. This approach will develop critical thinking skills to advance sustainability across spatial scales.
