We have been continuing on with our free OU course - Understanding Experiments. This time we were exploring osmosis. We used some slices of cucumber. First we weighed them and then put one piece into distilled water and the other into salt water. We left them for a while to see what would happen.
The cucumber in the salt water lost weight (by losing water through osmosis) whilst the cucumber in distilled water gained weight (by absorbing water).
