🔁 User Testing & Iteration Log

Students test their revised prototype with at least one person outside their team (another group or invited school community member). They use a short testing protocol with 3–5 targeted questions tied to their 'How Might We' statement and observe user interactions. After testing, teams revise their exhibit and individual talk structure, completing an iteration log that documents: what was tested, what users said/did (with quotes), what changed, and why. Close with a brief written daily reflection on how user evidence reshaped their economic explanation.
