- Ask pupils to plan an investigation to find the rule of balancing. Encourage them to plan how to collect data systematically to determine the pattern.
- Derive the principle of moments from their patterns and use them to calculate moments about a pivot. Help pupils to find anomalies in their readings and to identify the origins of these,
eg incorrect measurement, poor balance.

- plan to take appropriate measurements
- present results in a way which helps them identify patterns
- explain, in terms of experimental technique, how anomalous results might have occurred
- recall the principle of moments and apply it to a range of situations
