🚨 Dive Safety Showcase Briefing

Teams run an interactive exhibit station for guests using their final briefing board, labeled warming-device prototype, particle model visuals, and rescue dive route map. Each team gives a concise safety briefing that explains air-supply calculations, heat-loss evidence, and specific revisions made after the Coast Guard or marine safety review, then responds to audience questions and demonstrates one model or prototype feature. The teacher and guest use a performance rubric during presentations while classmates rotate as audience members when not presenting.
