Connect evidence to the explanation
100 g liquid water in a covered cup;26°C surroundings remain constant. 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.

Constructed teaching data: these values were invented for this activity, not collected in an experiment.
Elapsed time (min) | Water (°C) |
|---|---|
0 | 15 |
5 | 18 |
10 | 20 |
Fictional response 1: “It reads 15,18 and 20°C, so it changed.” Fictional response 2: “Energy goes from warmer to cooler, so something changed.”
1. What does each fictional response supply, and what connection is missing? Point to the evidence you would use.
2. Connect specific readings to the warmer/cooler parts and net energy transfer. Include what the table does not directly measure.
Optional prompts: What changed? Which part was warmer? In which direction is the net transfer? How is that consistent with the sample’s change?
