      Lesson details

      Learning outcome

      I can recognise that the remains of living things became fuels over millions of years, and that fossil fuels are non-renewable.

      Key learning points

      1. A fossil fuel is a natural fuel formed from the remains of living things over millions of years.
      2. The type of fossil depends on the original living thing and the amounts of heat and pressure.
      3. Fossil fuels have been used increasingly since the 1800s for heating, transport and generating electricity.
      4. Fossil fuels are non-renewable, as they cannot be replaced once they have been used up.
      5. Burning fossil fuels creates carbon dioxide and tiny pieces of solid matter, such as soot.

      Keywords

      • Fossil fuel - A fossil fuel is a natural fuel formed from the remains of living things over millions of years, such as coal, crude oil or natural gas.

      • Burn - When something burns, it is on fire.

      • Non-renewable - A non-renewable resource or material is one that cannot be replaced once it has been used up.

      • Soot - Soot is a very fine powdery substance created when fossil fuels are burned.

      • Carbon dioxide - Carbon dioxide is a type of gas in the air.

      Common misconception

      Pupils may think that fossil fuels have been made from fossils, such as the ones they may see in the classroom or museums.

      Explain that fossil fuels are the remains of living things that have been changed over millions of years by heat and pressure.

      Teacher tip

      Encourage pupils to think about when fossil fuels are used in their daily lives. For example, they may have come to school in a petrol car or have a gas oven at home.
