Teams model how guests flow through a theme-park queue, calculating wait times and testing a redesign that keeps lines moving without cutting ride capacity.

Setup

Print or hand-copy the essential prompt for Roller-Coaster Queue Laboratory, then set out only paper, pencils, and the common or recycled items needed for one test. Use a tabletop representation whenever the original version mentions a room, specialized device, or digital tool; the learning comes from the decisions and evidence, not elaborate scenery.

Activity

  1. Review the ride's capacity per cycle and predict the average wait time for a given guest arrival rate.
  2. Lay out a queue path on poster board and move token guests through it to model the wait.
  3. Time the simulated wait, find it's longer than predicted once arrivals spike, and redesign the queue path or add a switchback to fix it.
  4. Present the improved wait-time data to a park-operations audience, explaining the redesign.

Done when: The group has completed Roller-Coaster Queue Laboratory when it can present the improved wait-time data to a park-operations audience, explaining the redesign and point to the observation, measurement, comparison, or trial that supports its conclusion.
