Science at key stage 3    (Year 8)

Unit 8F: Compounds and mixtures

QCA
About this unit

In this unit pupils:

  • distinguish between elements and compounds and how they are represented by symbols and formulae
  • recognise chemical change as a process in which atoms join together in new ways
  • distinguish between compounds and mixtures
  • distinguish between chemical reactions in which new compounds are formed and the formation of mixtures

In scientific enquiry pupils:

  • decide how many measurements are needed for reliable results
  • present data as graphs
  • interpret and draw conclusions from observations and graphs
  • investigate temperature changes as liquids cool

This unit is expected to take approximately 7.5 hours.
