Laboratory 14

Laboratory 14 provided the absolute minimum of structure. On the board I wrote, "Determine the index of refraction for the glass panes." I provided only the glass panes. Orally I told the students, "If you need anything else, ask and, if the laboratory has the requested item, I will provide it." Laboratory ten included determination of the index of refraction of water, thus the students were not starting from a completely blank slate of possible ideas. One of the first requests was for rulers and meter sticks.
Sepe requests clarification of a value.
Eliander and Steward work on the problem.
Charlene requested a basin of water as part of her approach to the problem.
Nick built an air-layered glass stack as part of his approach to the solution.
