iiiDifferences between elements, compounds and mixtures in terms of particles. (Red only)
Scientific enquiry
ivBe able to apply knowledge and understanding of the particle theory of matter.
vBe able to write equations for simple reactions.
Suggested alternative starter activities (5–10 minutes)
Share learning objectives / What happens next? / Key ideas map
  • Check how much you know about elements, compounds and mixtures.
  • Use ideas about particles to explain chemical changes.
/ Pupils predict what happens next using the concept cartoon. / Pupils work in groups to add more detail to the outline Key ideas map.
