What students learn in AC9S2I02
A good investigation follows clear steps, manages risks and makes a fair comparison. Students change one factor, keep other important conditions similar and record what happens.
Learning sequence: Question → Plan → Safety check → Fair test → Record
Success looks like
- Suggest procedures
- Identify risks
- Follow safety rules
- Plan fair comparisons
- Record steps
Concept model and worked application

Revision Notes
Key idea: A good investigation follows clear steps, manages risks and makes a fair comparison. Students change one factor, keep other important conditions similar and record what happens.
Remember
- Suggest procedures
- Identify risks
- Follow safety rules
- Plan fair comparisons
- Record steps
Quick questions
- What comes before testing?
- What makes a comparison fair?
- Name one safety step.
- Why record the procedure?
If an answer is uncertain, return to the model and explain what each part represents before calculating or drawing a conclusion.
