🔍 User Feedback & Iteration Log

Teams test their prototype with at least two people outside their team (another class group, teacher, or invited adult). They use a short testing protocol with 3–5 open-ended questions focused on clarity, feasibility, and environmental impact. Students document direct quotes, observe user reactions, then revise their prototype during the same session. Each team completes an iteration log detailing what was tested, feedback received, specific design changes, and rationale for revisions.
