What students learn in AC9S9I04
This unit helps students build a clear, usable understanding of Select and construct appropriate representations, including tables, graphs, descriptive statistics.... 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: select and construct appropriate representations, including tables, graphs, descriptive statistics, models and mathematical relationships, to organise and process data and information.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- using spreadsheet software to present data in tabular and graphical forms identifying which sample properties, such as mean, median and range, are the most appropriate to use to make generalisations
- 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: select and construct appropriate representations, including tables, graphs, descriptive statistics, models and mathematical relationships, to organise and process data and information
- E1: using spreadsheet software to present data in tabular and graphical forms
- E2: identifying which sample properties, such as mean, median and range, are the most appropriate to use to make generalisations
- E3: applying algorithms to measure carbon storage of different vegetation types
- E4: applying ratios to accurately represent usable and waste energy in transfer and transformation diagrams such as Sankey diagrams
- E5: comparing the information provided by molecular models and word and balanced symbolic chemical equations when examining the law of conservation of mass
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.
