In class 7, we LOVE science - especially when we get to complete science experiments that test our prediction skills. We have been learning about changing materials and in this lesson we were learning about the different effects there can be when joining two materials together. In this experiment, we combined water with these different solids: sugar, salt, sodium bicarbonate, baking powder, sand and gravy granules. We observed that some of these sank, created a solution, floated or reacted. Our favourite was certainly the reaction to the bicarbonate of soda! As a class, we decided to keep: the sand, sugar and salt tubs and put them in our windowsill to observe what happens to them over the next few weeks.
