P · Bridge · Compare a claim with its support

Target: use new evidence to retain, narrow or change a particular claim—or remain uncertain. Prerequisites: read starts/°C/time/change, compare matched trials and identify conditions. Newest does not automatically mean most informative.

K5-D-P ·Two fresh 100 g samples;22°C surroundings;10 min;same covered setup/procedure. 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.

Retain = evidence remains consistent; narrow = limit scope; change = alter a conclusion; uncertain = withhold a confident conclusion. Decisions may combine, such as narrow and uncertain.

M0 · Model · Initial evidence

Work on this page first. Record a bounded claim before turning to the new-evidence page. Question: What does this record support about R’s 20-minute performance? A nominal classroom criterion is final water at or below 15°C in each supplied trial; it is not storage advice or a guarantee.

K5-D-M0 ·Fresh 100 g samples start 10°C in 22°C surroundings. Same sleeve versions, cups/lids,20 min, exposure and procedure within/across trials. 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.

Do not look ahead until you have recorded the claim. Keep this page for the revision.

M1 · Model · New evidence

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

K5-D-M1 ·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.

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