Contents
Outcomes
- Pupils can analyse results and identify direclty and inversely proportional relationships
- Pupils can evaluate their own practical work and look to improve upon their results
Specification References
Starter
- Review practical from previous lesson
Main Body of Lesson
- Go through "what makes a good graph" inluding how to find gradient, scales, labels etc.
- Pupils to use their data from the previous lesson and plot the following graphs:
1. average resistance against length
2. average resistance against area
3. average resistance against 1/area
- Ask pupils why the curved graph is less useful
- Discuss the concept of variables being directly proportional
- Pupils to take some data from their graph to e.g. to predict the resistance for a given length
- Discuss where errors could have arisen
- Discuss improvements which could be made to the investigation
