Today, Caroline gave us the task of creating boats from a given set of materials. We were allowed to "buy" the materials to use on our vessel, and afterward, we competed in a competition where the winner would be determine by price of vessel, amount of marbles it could hold, and how close our actual result was to our estimation. For some Apprentices, today was their last day. They presented their projects and it was interesting to see other peoples' representations of the various projects.
