Mairead's Reflection:
This activity was designed to get them to understand how to go from a semilog or loglog relationship to the original relationship. I would like to change how we phrase some of this to say something like "Notice when there is a linear relationship between log y and x then there is an exponential relationship between y and x." The thing they most get confused in during all of this is what relationship they are looking at - which becomes apparent in 4.4B and C when they have to plot their model against the original data and they are trying to plot it against the semi log or log log data. Overall I'm not happy with how this sequence of activities build but I think this one is pretty good - I'm not sure how to improve the conceptual understanding here.
