Science at key stage 3    (Year 7)

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

QCA

Health and safety

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

  • carry out a range of experiments which may be hazardous
  • observe gases which are toxic and corrosive

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.
