ae.02 Looking more at systems
- 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.
Base knowledge and understanding
Task 1 - A simple system
inputs | processes | outputs
Task 2 - Real life isn't a simple system!
Task 3 - Developing your understanding
Define these terms:
- avalanche / avalanching
- hoar frost
- wind-blown snow
- glacier flow
- surface meltwater runoff
- basal melt
- subaerial melt
- subaqueous frontal melt
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.
Task 5 - Changes to the system
Explain how the inputs, processes and outputs would have had to change to cause these changes in the Aletsch glacier.
