Many thanks to Mr. Stark for filling in as my substitute today. I spent the day in Shoreline for professional development as part of my Washington Alliance for Better Schools (WABS) STEM teacher externship program. In class today, students were scheduled to share their field trip experience with Mr. Stark, after which they were to receive an article to read along with a worksheet with questions about the reading and the field trip. This past June, the Seattle Times published the article Toxic algae bloom might be largest ever (or download the PDF), providing students with background content for the final phase of our unit. The worksheet of questions about the reading can be downloaded here.
