Reflection: Discourse and Questioning Why Do Leaves Change Color? - Section 2: Guided Practice - Experiment


This was a great experiment in theory.  The students had a lot of fun with it.  The part that was very difficult was getting them to understand what chlorophyll is.  When students cannot see something with their own eyes at this age, it is a difficult concept for them to grasp.  It would be really nice if I had access to microscopes in order to help them make this more concrete.

The other difficult part for students was the discourse between myself and the students.  It was hard to get them to answer my questions about what they think was going to happen with the filter paper and the "why". 

In the future, I think I would like to do more teaching about chlorophyll and use the microscope.  This will make it more concrete for the students.
