Reflection: Adjustments to Practice Enzyme Function: Exploring the Concept of Denaturation with Pineapples (Day 2 or 2) - Section 4: The Classroom Flow: Analyzing Data

 

I have used this lab procedure before but felt dissatisfied with the work students turned in.  It seemed to me that they really didn't understand the connection between what happened to the gelatin in each tube in relation to the type of pineapple used and how that relates back to enzyme action and denaturation.  It was very clear to me I had a great lab protocol that clearly showed complex connections and appropriate lab procedures using a well defined control, but that I wasn't navigating the conversation well enough.

What I did this year was really set up on the board what we could theoretically expect to happen in each tube based upon our basic knowledge about denaturation and temperature.  Once we were able to agree upon the theoretical results we should expect, it became more meaningful to the students to share out their samples that didn't fit our expected results and discuss the reasons for that discrepancy.  

By the end of this thorough discussion, students were able to clearly articulate both in conversation and in their conclusion paragraphs both the content area goals for this lab as well as make a thorough error analysis using appropriate science inquiry terminology.

Although my team was hesitant about making this a two day lab in the interests of time, my feeling is that whenever we slow down to go a bit deeper with our activities, the end result is students who can articulate their learning well beyond the specific activity and time frame.  We have been able to target enzyme action through multiple units of study this year and I feel that this foundational activity set up their understanding of enzyme structure and function throughout the course.
