Week 13

Monday, November 25, 2019: With the short holiday week, students who needed time to work on the Yellowstone Virtual Road Trip work from last week had the opportunity to do so; students who were caught up watched The Lost Worlds of Planet Earth from Season 1 of Cosmos.


Tuesday, November 26, 2019: Class began with a self-assessment with regard to work completed for the Yellowstone Virtual Road Trip project. Students evaluated their work via a checklist, turned in the checklist for assignment credit, and then received back the checklist in order to complete missing work.  Students who needed time to work had the opportunity to do so; students who were caught up watched The World Set Free from Season 1 of Cosmos.
