🖼️ Rehearsal Timeline Gallery Walk

Student teams stage the living timeline mural with artifacts, captions, maps, and QR audio stations, then run a timed practice gallery walk. Visitors inside the class use a feedback form focused on pacing, evidence use, chronology, and connections across the Gold Rush, Dust Bowl, Bracero Program, Great Migration, and Old Hollywood. Each student gives feedback to 2 peers, receives feedback, and marks at least two revisions in the investigation notebook.
