Science at key stage 3    (Year 8)

Unit 8H: The rock cycle

QCA
About this unit

In this unit pupils:

  • learn about the major rock-forming processes
  • learn how rock-forming processes are linked by the rock cycle
  • use the concept of rock texture as one of the key characteristics of igneous, sedimentary and metamorphic rocks
  • relate processes observed in other contexts, eg crystallisation, to processes involved in the rock cycle
  • consider processes operating on different timescales

In scientific enquiry pupils:

  • model rock-forming processes
  • investigate a technique for comparing the composition of limestones, evaluating different approaches
  • investigate differences between igneous rocks using both first-hand and secondary data

This unit is expected to take approximately 7.5 hours.
