compare the sizes of the two prunes the following day with one another using different methods to indicate the difference in size
-
If the prunes are of equal size:
Salt Water + Prune: Either it will remain the same size or slightly smaller and shriveled.
Pure Water + Prune: Swell and become larger and heavier
Methods to indicate size:
1. weigh each the night after compared to the night before and subtract
2. stick each in a graduated cylinder to measure volume
3. take a picture of each prune next to a ruler and measure in cm/mm
