Foundation tier notes:
- Any conversions between imperial units and metric units will be stated in the question.
- Conversions between capacity and volume will be given in the question.
- For a straight-line distance-time graph, know that the gradient represents speed.
Higher tier notes:
- Students should understand that, for example, the number of fish in a small pond cannot continue to grow in population indefinitely and that certain assumptions will be made or used when modelling, for example a 10% increase in population per year.
