For Gg week our science experiment was a test of density by seeing if grapes can float.  In the morning, we followed the experiment directions.  One jar contained plain water.  The grape sunk as expected.   The next jar had water and sugar.  The grapes did not float!!!  It was a good lesson that sometimes a scientist’s experiment may fail. In the afternoon, we tried again using salt and it was a success. The salt water is more dense than the grapes, therefore they float!
