Why this why now

This unit builds on pupils’ prior learning from Earth's resources, where they explored how natural resources are utilised and the importance of sustainable management. It deepens their understanding by examining the carbon cycle and its role in climate change, focusing on human impacts such as carbon emissions. This prepares pupils for the next unit, Atmosphere and changing climate, where they will apply their knowledge to explore the composition and evolution of Earth’s atmosphere and the ongoing impacts of climate change.

Prior knowledge requirements

  • Rocks may contain sand, grit, bits of seashell, fossils or crystals.
  • Sedimentary rocks contain distinct grains that are stuck together.
  • Sedimentary rocks may contain fragments of shell or fossils, or larger pieces of grit or pebbles cemented together.
  • Igneous rocks contain crystals that point in many directions.
  • Metamorphic rocks contain large crystals that all line up.
  • Most rocks are a mixture of one or more types of mineral, or of fragments of other rocks and fossils.
  • Burning coal, oil or gas in power stations makes carbon dioxide gas and other pollutants.
