🌍 Evidence Night Hearing

Teams deliver a 5-minute student-led presentation for Local Waters, Local Air: Evidence Night using their poster, pollution source map, filtration and boiling-point data tables, and revised chemistry explanations. Audience members, including classmates and the school gate security guard, ask questions in a community-hearing format, and teams must answer with evidence from observations, sample data, and at least one clear "because...so..." causal explanation. The teacher assesses the group portfolio and presentation package during the hearing, and the session closes with a whole-class circle reflection on one chemistry idea clarified, one teamwork strength used, and one next challenge.
