This is a great assignment for review if you are going to be out. It pushes students to explain the concept of Hydrosphere Stewardship, using vocabulary terms and topics taught within this unit. Students are giving the task of writing a letter to a classmate named Bubba to get him caught up to speed on what has been happening in class. There is a rubric attached to use for grading and students can grade each others papers. It is a great reinforcement of the topic. I really pushed my student to also illustrate as much as they could.
