Work together to rebuild the dusk observing schedule.
Welcome to the dusk observatory. The crew needs a slot long enough for setup and travel before the observing window closes. Your team has the original records on the table. First recover five pieces of information, then use the final plan to rebuild the dusk observing schedule. Keep every result beside its badge so another teammate can check your reasoning.
How your team will think
Combine before/after reports and work-and-travel windows.
Keep event names, times and badge labels together. Test the printed before, after and availability rules before accepting a schedule.
Set up in one room
Print the six player sheets and two record sheets for each team. Keep answers and hints with the host.
Lay out Departure windows (minutes after opening), Event cards, the remaining clue sheets and the final plan. All task records are printed inside the sheets; no extra prop is needed.
After each clue, pass roles one seat clockwise. With two players, combine Reader with Recorder and Checker with Builder. With five or six, add a second checker and a source finder; everyone explains one decision.
Ages and durations are design estimates. Choose the pace and reading support that suit your group.
