🧭 Design Brief Checkpoint

Each team submits a concise design brief with its user-defined problem, evidence set, selected scenario, physics rationale, and one prioritized How Might We statement. Teams include a quick collision sketch or momentum representation showing why the scenario matters, then meet with the teacher for a milestone conference to verify that the brief is grounded in user evidence and ready for prototyping in the next phase. Students end with a short voice reflection on what changed after critique and what evidence still needs testing.
