The sculpture-room pans · complete picture wordsYear 4 Science · T1 W7–8 · Aids / A16 alternative · Text version

Made-up practice record. A pretend sculpture room has matching pans, equal starting water amounts, the same place and the same 40-minute review interval. A taught mL procedure gives supplied water-loss readings U=5 mL, V=10 mL and W=0 mL. Pan X has no recorded reading; pan Y spilled and is invalid for this comparison. A second group's matched record gives V=5 mL. No cause for differences is supplied. These are invented records, not your own instrument use or observations.

Q1: Represent U, V and W with their unit. My response: __

Q2: Which record is zero, which is missing, and which spilled? My response: __

Q3: Compare the two V readings and give a next check. My response: __

Q4: Do the records prove V always loses 10 mL? Why? My response: __
