Year 4 Ocean love practical Science lessons and in our last lesson I asked to children to make predictions about a range of materials. They needed to guess whether or not they would pass through a sieve and whether they were categorised as solids, gas or liquids. It was fun testing out the materials and we concluded tiny particles in materials such as flour made them behave like a liquid. However, they were actually solid. This is a simple investigation that can be carried out at home together.
