Science at key stage 3    (Year 7)

Unit 7F: Simple chemical reactions

QCA

Health and safety

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

  • work with acids
  • observe materials burning in oxygen
  • burn liquid fuels
  • plan their own investigation into burning a candle

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.
