I found scale to be challenging for me to understand. It has been a long time since I have worked on scale. The formula's were familiar but the application was difficult for me. I needed to ask assisstance when plugging in the numbers. I thought it related to inquiry because it really allowed the participants to run with their ideas. I'm wondering, what about the students who had little knowledge of the formula's? Would the students be well versed in figuring out the math, so it did not interfer with the science aspect of the lesson? I know as one of the struggling participants, I became frustrated when I did not know where to continue.  I would not have moved on until everyone had a sense of understanding. I guess time was the issue. As a teacher would you continue the lesson another day for struggling students?

The measuring of objects downstairs really put scale into perspective.
