Science at key stage 3    (Year 9)

Unit 9B: Fit and healthy
Section 7: How does alcohol affect the body?

QCA

Objectives
Children should learn:
  • that alcohol alters behaviour
  • that excessive use of alcohol can damage the liver and developing foetus
  • how to locate information within a text and to identify key points

Activities

Outcomes
Children:
  • Explore pupils' ideas about alcohol and its effects through written answers to a quick quiz.
  • Prompt the pupils to explain what is meant by a driver being 'over the limit'. Discuss with pupils the reasons for control and advice on alcohol consumption, eg a limit for driving, recommended weekly consumption, minimum age of 18 for purchase of alcohol. Help pupils to use secondary sources, eg testing results, ICT simulations, video clips, to explore the effects on reaction time and driving skills.
  • Provide pupils with secondary sources to help them annotate a diagram showing the specific effects of alcohol on body organs and the developing foetus.
  • Pupils go back to the quiz they completed earlier to amend their answers.
  • describe the effects of alcohol on behaviour, eg reaction time, reduction of inhibition
  • describe the effects of alcohol on the liver, diet and developing foetus
  • show in their annotations that they have identified the key points

Points to note
  • Teachers will be aware of the need to be sensitive to the circumstances of individual pupils and their families.
  • There are several alcohol education packages available containing resource material, such as effects on reaction time, information about units and alcohol content of drinks. Some include quizzes.
