🧪 New User Prototype Test

Teams test their refined interactive playground force station with at least one new user (student, staff member, or recess monitor) who has not seen the prototype before. The user completes the live investigation (e.g., ramp test, magnet wall demo) while the team records observations, direct quotes, and questions about force diagrams, kinetic energy graphs, and clarity of instructions. Teams ask at least two follow-up questions about how clearly the forces and motion were explained.
