Answer guide · AC9S1I02
- So the ramp does not slip or collapse during the test.
- A clear floor area away from stairs, roads and other people, with teacher supervision.
- For example, clear the space; hold each paper at the same low height without climbing; release and observe one at a time.
- The procedure helps keep people safe and makes the results easier to compare.
If help is needed: A safety rule should match the actual investigation. ‘Be careful’ is less useful than naming the action that prevents a problem.
