This term we are hoping to develop some of our scientific enquiry skills. By doing a different experiment every few weeks we should be able to ask and answer some challenging questions. This week Y4 learnt all about water stratification, which is where a solution creates a barrier. To show this, we experimented with skittles! The children arranged their skittles in whichever way they wanted – some chose to arrange them randomly and some chose to put them in to a pretty pattern. After placing water in to the middle we watched the colour spread. Notice how the colours don’t mix? That’s water stratification!
