This activity goes a little differently every time I teach this class depending on the particular group of students. Some are very comfortable with Mathematica and find it very cool while others need a little more help. This activity took one class period with some work having to be finished outside of class. I did talk to them about the expectation that they would work on Mathematica outside of class by coming back to the computer labs later in the day. There are not a lot of activities where we ask them to do that but there are a few. It's always fun to hear a few students genuinely amazed at the fact that they can see their modeling function show up on top of their data :) Nothing went very different from expected on this one.
