The carbon cycle

In the Atmosphere and Changing Climate unit, pupils will build on their understanding of the carbon cycle and climate change to explore the evidence for the composition and evolution of the Earth's atmosphere, and the effects and mitigation of increased levels of carbon dioxide and methane.

In the Earth's Resources unit, pupils learned about the composition of rock, the interior of the Earth, and how igneous and metamorphic rocks are made by heating.

This unit explores the rock cycle and the formation of igneous, sedimentary, and metamorphic rocks. It also examines the atmosphere's composition, human-induced carbon dioxide production, and its impact on climate. Focus is on interpreting data, identifying patterns, and presenting explanations.
