🧪 Wear-Test Metrics Mini Lab

Teams rehearse how to collect usable evidence by checking strap strength, closure reliability, comfort, fit, and message clarity on their repurposed textile item. Students use a teacher-provided test card, stopwatch, spring scale or hand-pull comparison, and photo checklist to define what counts as success and what data can be gathered in one class period. The class also reviews how to record observations without overstating results and how to separate user opinion from physical performance data.
