Dissolving substances



This  term Class 4 will become trainee Scientists investigating everything to do with materials.  Today  made predictions and we investigated dissolving substances in water.  We looked at dissolving sugar, salt, flour and sand.  If the subtance dissolved it made a solution and it was classified as soluble.  If the substance didn’t dissolve then it was classified as insoluble.  We were able to make links with this activity and what we already knew, including that sugar must dissolve because people have it in tea and sand wouldn’t dissolve otherwise there would be none at the bottom of the sea.
