Blindfolded 'Explorers' were guided by Navigators and Ship's Pilots across the courtyard. The pilots used a magnetic compass and a pre-calculated time/distance chart to direct the route, and to help the Log keeper write down the information to keep track of the Explorer's route. At each stop, the Navigator used a quadrant to measure the angle to the top of two reference points, which were the lamp posts in the courtyard. Each group also had a Ship's Captain who was responsible to keep the group organized (and the Explorer safe while they were moving).
The students were able to better understand the challenges faced by the early explorers as they headed into unknown territory, and the difficulties of following a route which someone else had recorded.
