Energy, Matter, and Organization: Potato Catalase Lab Analysis

We continued our work from yesterday, with students re-grouping to share the data from the lab (and creating T-charts of the data) and using it to create graphs using graph paper.  Students then analyzed the graphs to answer questions about what the data demonstrated.  The analysis questions were intended to help prepare students for the types of questions they might see on the Biology End Of Course Exam in May, as well as deeper questions that better reflect the thinking of highly capable high school students.  For example, students were pushed to describe the enzyme’s rate of activity (the rate of change in their graph).  Students have learned how to calculate the slope of a line in algebra, but it is not necessarily a concept students readily apply to biology.  Students who finished continued working on their lab reports using the Chromebook, creating digital versions of their data tables and a few even created graphs in Google Sheets and copied them over to their Google Doc lab report.  Students will finish the lab reports tomorrow.
