Reflection: Coherence Can You Hear Me Now? - Section 3: One Variable at a Time Please


The power point presentation helped to efficiently walk the students through the lab. The images kept the students engaged. I kept the procedure slide up while students were working through the lab as a reference.

Some teams were confused between the material samples vs the material they would use for the lab. Next time I will add a slide to explain the difference between material samples vs materials to use for the sound insulation to help clarify the difference.
