Our Changing Earth Incursion (Levels 3/4)

Theme: Science – Earth and Space Sciences
Level: 3 & 4
Students will explore the natural processes of weathering and erosion as well as human impacts that change the landscape.


  • Discuss prior knowledge of natural and human forces that change the landscape;
  • Explore the ‘rock cycle’ and classify samples of sedimentary, igneous and metamorphic rocks;
  • Investigate weathering caused by physical actions such as sand blasting and ice expansion;
  • Observe the effects of chemical weathering;
  • Investigate wind and water erosion and deposition of sediments;
  • Investigate water absorption by different types of soils;
  • Link the effects of different human activities on the earth’s surface such as logging, mining and urbanisation.
