0–3 puzzle: Write 22 °C → −5 °C beside the public 300 K difference; ask what happened to the offset. 3–7 source: Identify two invented archive readings; no real time-series inference. 7–12 teach: On the temperature-and-uncertainty mat, apply syllabus convention T(K)=T(°C)+273 to each value: 295 K and 268 K. Subtract the converted values: −27 K change, or a 27 K decrease; a 1 °C interval is a 1 K interval. State that +273 is the syllabus's rounded offset. 12–20 route: Learners produce a labelled two-column correction. 20–23 audit: Check that Kelvin temperatures are not written with a degree sign and that an interval is not given another +273. 23–25 exit: Give both absolute values and decrease.
