Cells & Homeostasis: Intro to Seahurst Park PBL

We began class with a pre-assessment of student prior knowledge of the learning targets encompassed by the final segment of our unit on cells and homeostasis.  Next we launched the Seahurst Park PBL (problem-based learning) with a PowerPoint depicting a scenario familiar to students now that they have recently visited Seahurst Park and learned about harmful algal blooms locally in Puget Sound, as well as on a much larger scale off the West Coast (from Tuesday’s reading assignment).  We concluded the class period with students taking the lead in creating the Know/Need to Know chart on the white boards at the front of the classroom.  Student work is shown below, grouped by class period (click to enlarge).
