📏 Mars Test Plan Calibration

Teams revisit their design brief, decision matrix, and prototype plan to confirm measurable test variables for water, food, shelter, air, and energy systems. Using timers, thermometers, mass/volume measures, observation tables, and simulation variables, students tighten weak measures into fair tests and set target benchmarks for success. The class examines one sample data table and one sample claim-evidence-reasoning explanation before teams finalize their own test sheet.
