Introduction to solids, liquids and gases

This week we will look at the states of matter: solids, liquids and gases. Children need plenty of opportunities to explore changes in state, such as evaporation and freezing. Although an understanding of particles is not required at primary level, modelling the particles in a substance can help children to understand the nature and properties of each state.

We start this week with some subject knowledge and the particle model of solids, liquids and gases.
