0–3 puzzle: Read the lunch-crate poster and ask which word makes an unsupported safety promise. 3–7 source: Separate solid wall, enclosed air and facing surfaces; no real lunch temperature is known. 7–12 teach: Put conduction, convection and radiation on three distinct arrows on three-paths; neither the drawing nor a mechanism alone determines magnitude. 12–20 route: A/B/C makes a three-path map and a cautious replacement sentence. 20–23 audit: Partner checks that “within the air” is not mistakenly called conduction through an evacuated space. 23–25 exit: Name the three possible paths and the missing food-safety evidence. Offer fresh Check A in a later school-selected slot only if new to the learner.
