The online geology lab for community college students was developed during two years of forced online synchronous learning brought on by the COVID-19 pandemic. This open educational resource is a cohesive laboratory manual intended for two-year, non-major college students from the New York area.Each lab is accompanied by a Teacher’s Guide and an online answer sheet (formatted for the Blackboard learning management system). A multiple-choice format is used for many questions, making the labs easy to grade.
The emphasis of this course is to use Trace Element Geochemistry to understand the origin and evolution of igneous rocks. The approach is to discuss the parameters that control partitioning of trace elements between phases and to develop models for the partitioning of trace elements between phases in igneous systems, especially between minerals and melt. Subsequently, published papers that are examples of utilizing Trace Element Geochemistry are read and discussed.
