Changing State – Solids, Liquids & Gases

Download this 19-slide PowerPoint about changing state. If you are teaching children about the differences between solids and liquids and gases and want them to recognise that the same material can exist as both a solid and a liquid, then this PowerPoint will help. The PowerPoint describes changes that occur when materials are heated or cooled and explains what reversible and irreversible changes are. This is a great resource to use for KS2 primary science. The pack also includes ideas for activities that will develop children’s thinking skills for this topic.
