Reflection: Flexibility Getting Food to The Cells (2) - Section 6: Collaborative


I've done this as a student lab in the past.  This year I wasn't able to do that so I did it as a demonstration instead.  As I reflect, I think this may be a better approach.  It really helped me to control the pace of the lab and that scaffolding the learning.  

In the past, I have always had a few students that get caught up in the colors and using the test tubes and they totally miss the purpose and the results.  In a demonstration, I control how quickly the procedure unfolds, where to stop and discuss, and so am able to control the environment so we can dig at the meaning derived from the evidence.  

I wouldn't do lab demonstrations everyday, because it is important for the kids to build their own skills, but it worked well today.
