Science at key stage 3    (Year 7)

Unit 7G: Particle model of solids, liquids and gases

QCA
About this unit

In this unit pupils:

  • learn how the particle model can be used to explain differences between solids, liquids and gases
  • explore how experimental evidence relates to theories and models

In scientific enquiry pupils:

  • use the particle model to explore the interplay between scientific theories and evidence
  • evaluate whether evidence supports or refutes explanations of phenomena

This unit is expected to take approximately 7.5 hours.
