[chuck] in Biltmore sticks, El Rincon, Science

After everyone had finished making their Biltmore sticks (see What I Do), I had them line up and measure the diameter of a nearby oak tree. They were to measure the tree, but not tell anyone else what they got. When everyone had finished, we compared the results. Everyone was pretty nervous about this, but they (almost) all assigned the tree to the same 5 cm diameter class.
