Soluble Solids

Today we have been learning about materials which are soluble and insoluble.  We had to carry out some experiments to find out which materials would dissolve and which wouldn’t.  We had to test sand, sugar, salt, chalk, coffee granules, gravy granules and rice.  We put them in some water and gave them a stir.  If they dissolved then we recorded in our results table that they were soluble.  We were quite surprised by how many were actually insoluble.  We decided that if we had used warm water we may have had different results.
