Science at key stage 3    (Year 9)

Unit 9G: Environmental chemistry

QCA

Health and safety

Risk assessments are required for any hazardous activity. In this unit pupils:

  • investigate soils
  • use a solution of sulphur dioxide
  • use dilute solutions of acids

Model risk assessments used by most employers for normal science activities can be found in the publications listed in the Teacher's guide. Teachers need to follow these as indicated in the guidance notes for the activities, and consider what modifications are needed for individual classroom situations.
