A ready-to-teach PowerPoint scaffold for a one-hour Year 4 science lesson on states of matter.

Pupils compare solids, liquids and gases, explore how the tiny particles behave in each state, and learn how heating and cooling cause melting, freezing and evaporating. It links these ideas to the water cycle, with a sorting ‘state detectives’ task and a puddle-evaporation investigation.

It covers the Year 4 ‘states of matter’ objectives in a visual, investigative way.
