Later assessment: new environment record

Later check · One new environment record

100 g, start 10°C, room 28°C, 20 min. Final ≤15°C in EVERY trial; ≤4 tokens; ≤18 mm added thickness. Covered liquid water; cups/lids, mass, starting temperature, duration, exposure and reading procedure match within and across trials. Surroundings stay at the stated room temperature. No ice, phase change, active heating/cooling, direct sunlight or meaningful evaporative cooling. Each trial uses fresh samples. Accuracy is not supplied.

Supplied design record

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

Design	Tokens	Added mm	Trial 1 final °C	Trial 2 final °C	Trial 3 final °C
X only	4	16	17	17.5	17

1. Does X meet the 15°C criterion in this new record? Compare the new room with the initial record. What should be retained or narrowed, and can you rank X against Y at 28°C?

2. Suggest a next design or comparison while keeping the 4-token/18-mm limits. What would you do if the next readings were close or variable and accuracy was unknown?
