🌊 Community Water Quality Design Presentation

Teams deliver an 8–10 minute formal presentation to classmates and the teacher acting as community stakeholders. Presentations must trace the full design journey: user interview insights (with direct quotes), empathy map synthesis, water quality data (DO, pH, turbidity, phosphate), BOD explanation, defined HMW statement, multiple solution concepts considered, two documented prototype iterations, final tested model, and remaining gaps. Audience members complete structured feedback forms aligned to NGSS standards and AP lab expectations, followed by a brief Q&A where presenters must defend claims using evidence. Students conclude with a short written reflection on how testing and critique refined their solution and what they would test next.
