The document distinguishes between transfer and transformation, with transfer being the movement of something from one place to another and transformation being an actual change of state. It also distinguishes between flows, which are inputs and outputs, and storage, which involves transforming something into a form that can be used later. Finally, it discusses constructing and analyzing quantitative models that draw or analyze flows and storage, and evaluating the strengths and limitations of such models.

- 1. Describe Transfer and Transformation • Transfer - just a movement from one place to another ….water mountain to ocean.. • Transformation - actual change of state or material -- liquid water/evaporates… CO2 to sugars/starch in plant . 5/13/2013 Author-Guru IB/ESS 1
- 2. Distinguish flows and storage • Flows are input and output • exmple….input food -- output wastes energy • Storage -- usually a transformation into a form of matter/energy that can be used later…… 5/13/2013 Author-Guru IB/ESS 2
- 3. Construct & Analyse Quantitative Models • Actually draw or analyse a drawing of flows (inputs/outputs) and storage 5/13/2013 Author-Guru IB/ESS 3
