Unit focus

  • Students learn to investigate the observable properties of solids and liquids and how adding or removing heat energy leads to a change of state. They use the visual model, precise vocabulary and evidence to explain and apply the concept.
  • Use this routine: Observe → Model → Investigate → Record → Explain.
  • Watch for liquids have no volume: Liquids have a definite amount even though shape changes.
