Simulate a civic decision with transparent roles

Design a fictional classroom simulation of [CIVIC DECISION] for [AGE GROUP] with [CLASS SIZE]. Give role cards with distinct but fair interests, an evidence packet of clearly fictional facts, a timed hearing, decision rule and reflection questions. Avoid real-party campaigning, invented law presented as current or assigning students personal identities they did not choose. Include an observer role and accessibility options. Check that no role can win simply by holding secret information and that participants can distinguish the simulation from the real local process.
