Y4 Solids and Liquids

Pupils learn that some solids can be hard and strong, while others can be flexible and/or brittle. They also learn that most solids will melt when warmed or heated and will turn into a liquid. The also learn that liquids will flow and spread whereas solids remain rigid and keep their shape. They also learn that liquids can turn into a solid when cooled or frozen.


Learning Objectives:

  • PoS - compare and group materials together, according to whether they are solids, liquids or gases
  • NaG - pupils should explore a variety of everyday materials and develop simple descriptions of the states of matter (solids hold their shape; liquids form a pool not a pile; gases escape from an unsealed container)
  • WS - pupils should group and classify a variety of materials
