🧪 Prototype Test Plan Mini-Lab

Teams study 2 short model test plans for a shade, recycling, or planting solution, then create their own one-page testing plan using a teacher template. They name the user need, list materials, choose one simple monitoring method, and decide what evidence they will record during testing such as litter counts, temperature comparison, water use notes, or user comments. Students end by checking that each test matches their criteria and constraints from the previous phase.
