What students learn in AC9S2I05
This unit helps students build a clear, usable understanding of Observations with predictions and others’ observations, consider if investigations are.... 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: compare observations with predictions and others’ observations, consider if investigations are fair and identify further questions with guidance.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- comparing their observations of changing shadow length across the day with their predictions and the patterns observed by others comparing observations of sounds with those of others and considering if we all sense sound in the same way
- 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: compare observations with predictions and others’ observations, consider if investigations are fair and identify further questions with guidance
- E1: comparing their observations of changing shadow length across the day with their predictions and the patterns observed by others
- E2: comparing observations of sounds with those of others and considering if we all sense sound in the same way
- E3: proposing ways to ensure that the same sound is produced in an investigation in order to keep the investigation fair
- E4: comparing findings from investigations about physically changing a material, such as cutting and folding, and exploring questions that investigate similar changes to different materials
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.
