🧪 Fair Test Setup for Energy Models

Teams rehearse how to run one controlled test on their school energy solution model using the variables and measures already planned in the previous phase. Students use timers, tally charts, thermometers, light meters, or observation checklists as appropriate to their design, and the class briefly revisits how to keep conditions the same except for one changed variable. Each team completes a quick test rehearsal and checks that every teammate has a role for implementation day.
