Timeline of the Early Earth part of Cutting Edge:Online Teaching:Activities for Teaching Online
Students assemble timelines of the early evolution of Earth's atmosphere, lithosphere, biosphere, and hydrosphere by examining data from Archean rocks and minerals.
Introduction to Geologic Field Methods part of Cutting Edge:Course Design:Goals Database
This course is designed to give students repeated practice in field mapping methods - for students in areas without huge exposures of great outcrops (e.g., Missouri). Every class meeting, the students will be asked to map a set of mock outcrops: rocks placed around the classroom to simulate a field site. These short exercises will build progressively through the semester, adding more and more challenging concepts and requirements. Lectures will present new concepts through the lens of that day's mini-mapping assignment. Reading assignments will provide perspective on both the skills needed to do these mini-mapping assignments, and on the field areas on which these assignments are modeled.
