ae.02 Looking more at systems

Content

  • Statement of inquiry
    • Scientific and technical innovators need to understand how power affects the processes that occur within systems.
  • Factual questions [Remembering facts and topics]
    • Define precipitation, accumulation, ablation, sublimation, basal melt, plucking and abrasion.
  • Conceptual questions [Analysing big ideas]
    • What could happen when the inputs to a system change?
  • Aims of this lesson
    • To further develop your knowledge and understanding of systems.
    • To look at glaciers as a system in more detail.
    • To start to explore the consequences of changing elements within a system.

Task 4 - Applying your understanding

Annotate the terms onto a single (top points) photograph of a glacial landscape (or maximum three photographs) to show your understanding of where these processes happen and where they take place.
