What students learn in AC9S8I01
This unit helps students build a clear, usable understanding of Develop investigable questions, reasoned predictions and hypotheses to explore scientific.... The goal is not to memorise one answer pattern. Students should be able to explain the idea, recognise it in a new example and apply it in a short practice or worksheet task.
- Start with the main idea: develop investigable questions, reasoned predictions and hypotheses to explore scientific models, identify patterns and test relationships.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- discussing what is meant by a causal relationship and examining how causation is different from correlation developing investigable questions to test causal relationships, such as: ‘How does the concentration of a salt solution affect plant cells? How does the amount of sunlight affect the amount of electricity produced by a solar cell?’
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.
Curriculum coverage and elaborations
The content description and elaborations below show the curriculum ideas taught in this unit. Items marked as teaching context support lesson planning but may not appear in the initial eight-question activity.
- Content description: develop investigable questions, reasoned predictions and hypotheses to explore scientific models, identify patterns and test relationships
- E1: discussing what is meant by a causal relationship and examining how causation is different from correlation
- E2: developing investigable questions to test causal relationships, such as: ‘How does the concentration of a salt solution affect plant cells? How does the amount of sunlight affect the amount of electricity produced by a solar cell?’
- E3: developing investigable questions to explore scientific models, such as: ‘How do the shapes of the continents support the theory of plate tectonics?’
- E4: predicting what will happen when conditions change in a given scenario or phenomenon, such as: ‘When materials of less resistance are used to transfer electricity there will be less heat energy produced’
- E5: formulating hypotheses such as: ‘An earthquake of greater magnitude will cause more damage because there is more energy transferred’
How to use this unit
Read the topic guide, use the teacher slide for instruction, then complete the Worksheet, Practice and Test. These three activities use the same eight-question unit bank.

- Describing what is seen without connecting it to a question, pattern or prediction.
- Using everyday words only and missing simple scientific vocabulary.
- Changing more than one thing in an investigation, which makes the comparison unfair.
