Fossil fuels and electricity

• The learners are reminded of what they had learnt about mains electricity in grade 5.

     [Possible answer: It is electricity that is transferred from a power station to a circuit, referred to as the grid, to our homes and back to the power station again.]

• Greet the learners.
• Let the learners picture life without electricity and discuss how their lives would be affected if:
  • all the traffic lights did not work;
  • they cannot use any electrical appliances at home;
  • no petrol stations or businesses are open at night.

• The learners will think, reason and share their answers. [possible answers]

• No traffic lights:
  • There would be chaos if the traffic lights do not work.
  • Presently some drivers do not stop when the robots are out of order.
  • It would be very difficult for impatient drivers.
  • The traffic would pile up.
  • Many accidents can occur.
  • Drivers would speed past pedestrian crossings.
  • It would be very dangerous for pedestrians to cross the roads.
  • There would be a delay in deliveries to the shops.

  • Businesses will be forced to close down due to a decrease in sales.
  • No quick take-away food.
  • No open malls to shop at night.

• The four groups discuss the allocated slide per group:
• Group 1: The world without electricity.
• Group 2: No open petrol stations at night.
• Group 3: No electricity to use appliances at home
• Group 4: Chaos due to traffic robots that do not work
• Each group chooses a scribe and someone to report back.

This will refresh the learners’ minds about fossil fuels.
