Description of the activity/assignment
Students analyze a Quaternary pollen diagram from lakes in Bladen County, NC. This diagram contains (from the top down) the current deglaciation, the last glacial, and the previous interglacial. Students These lakes occur in Carolina Bays and students also evaluate a proposal that meteorite impact created the Bays.
Determining whether students have met the goals
Compare student answers to the solution set and also evaluate their reasoning to open-ended questions.
