The display-tray records
Made-up practice record. A museum display compares water lost from matching trays over the same 30-minute interval, using the same taught mL reading procedure. Start amounts, place and tray type are matched. Different display labels name trays J, K and L; the source does not specify a cause for differences. The valid supplied lost-water values are J=10 mL, K=0 mL, L=5 mL. Tray M has no recorded value. Tray N spilled, so its value is invalid for this comparison. Another group's matched record gives J=5 mL. These are invented supplied records, not measurements you made.
Four questions
- Make a table or columns for J, K and L. Keep the unit.
- Which record is zero, which is missing, and which had a spill?
- Compare the two J readings. What could you check next?
- Can these records prove J always loses 10 mL? Explain.
