New model evidence and blank revision record

New evidence

Now compare this record with your original claim. Keep all raw readings.

R only: fresh 100 g,10°C start,20 min, same R version/cup/lid/exposure/procedure. All surroundings now 28°C. S was not tested. Covered liquid water; no active heating/cooling, ice, phase change, direct sunlight or meaningful evaporative cooling. Room, cup, lid and supporting surfaces are at the stated surrounding temperature; it stays constant. Readings represent the sample temperature with a consistent procedure. This is a paper scenario, not apparatus instructions.

Additional trials in changed surroundings

Constructed teaching data: these values were invented for this activity, not collected in an experiment.

Fictional claim to evaluate: “R keeps water at or below 15°C in every room.”

1. What changed? Which earlier condition-specific statement can stay, and which broader claim needs revision? Can these new results rank R against S?

2. Use the next-page revision record. Explain why this is a scope change rather than proof that the first record was wrong.
