A system is set of interacting parts that create a whole.
It will follow a process.
It will have steps/stages that are causally linked.
It will have a beginning that triggers effects and will result in an end product or result.
When you analyse a system you understand how it works and why it works.
These are the steps to analyse a system:
1. I identify something as a system (I can explain why it is a system)
2. I state all of the parts of the system and how they work
3. I change one part of the system to see what would happen
4. I explain how the one change made the system change
5. I make conclusions about how the parts interrelate (importance, order, amount needed, comparison to other systems)
Let’s try this with the process that forms stalactites in caves.
Together as a class go to this webpage-read and take notes to analyse stalactites as a system.
Now use these websites to analyse bushfires as a system:
While doing so keep this in mind:
- We have defined natural disasters in part by their effects on humans.
- So, as you identify the parts of the system, consider where humans fit in.
- How does the result affect us?
How might our actions (emergency services; careful planting of trees, back burning, careless installation of power-lines, littering, global warming) be part of/change the system?
