Understanding matter is an important part of science. This is the first of two KS2 Science quizzes on the three states of matter - solids, liquids and gases - and it focusses on how they behave differently.
Everything is made up of matter. Matter can be in these different states: solid, liquid or gas. If you look around, you can see all sorts of objects. These are solids. Ice is solid water. You might have a drink - hopefully not near your computer! Drinks are liquids. Air is the invisible matter surrounding you. Air is a mixture of gases - oxygen and carbon dioxide for example. Steam, or water vapour, is water in the form of a gas.
