Unit 9B: Fit and healthy
Section 10: a. What effects do drugs have?

QCA

Objectives

Children should learn:
  • that a drug is any substance that changes the way the body or mind works

Activities

Outcomes

Children:
  • Explore pupils' perceptions of drugs by providing a list of well-known substances, eg paracetamol, cannabis, tobacco, penicillin, ecstasy, calamine, branded antiseptic. Ask the pupils to divide the list into drugs and other substances, then categorise the drugs into different groups. Ask the pupils to explain the criteria or reasons for their categories.
  • Explain what a drug is and the distinction between different categories of drug.
  • Discuss with pupils their perceptions of the dangers of drugs, eg widely used, side effects, addictive, likely to cause death. Use secondary sources to investigate the accuracy of their perceptions of recreational drugs. Help pupils present their findings as a 'fundamental facts' chart for use by year 9 pupils in other classes or for later year 9 groups.
  • categorise drugs into over-the-counter and prescription drugs, eg penicillin, paracetamol, recreational drugs, eg caffeine, alcohol, nicotine, and illegal (unless prescribed) drugs, eg amphetamines, cannabis
  • recognise that there is some overlap between different categories of drug
  • recognise that prescription drugs can have side effects and are potentially dangerous
  • explain addiction and identify addictive drugs

Points to note

  • Teachers will be aware of the need to be sensitive to the circumstances of individual pupils and their families.
  • Liaise with PSHE teachers to ensure the same materials are not being used.
  • Many outside agencies, eg drugs education units, can visit schools to provide discussion material and factual information.
