Science at key stage 3    (Year 9)

Unit 9G: Environmental chemistry

QCA
About this unit

In this unit pupils:

  • learn that rocks, soils and building materials have a variety of chemical characteristics
  • learn that chemical weathering alters rocks and building materials over time
  • consider how the atmosphere and water resources are affected by natural processes and the activity of humans
  • consider how environmental conditions are monitored and controlled
  • distinguish between different environmental issues

In scientific enquiry pupils:

  • consider how scientists work to monitor the environment
  • decide on the suitability of secondary sources for providing information on a particular question
  • consider how evidence for climate and environmental change needs careful interpretation
  • evaluate the evidence obtained
  • investigate environmental change using evidence from secondary sources

This unit is expected to take approximately 7 hours.
