Keep readings in one row
Keep readings in one row
Equal 100 g water samples in a 24°C room; matching cups, lids and method. Same 10-minute interval.
Start and finish
Constructed teaching data: these values were invented for this activity, not collected in an experiment.
Sample | Start (°C) | After 10 min (°C) |
|---|---|---|
E | 12 | 16 |
F | 12 | 19 |
1. Trace E from start to finish, then F. Calculate each increase. Check a fictional answer: “E changed by 7°C because 19 − 12 = 7.”
