What students learn in AC9S7U01
This unit helps students build a clear, usable understanding of Investigate the role of classification in ordering and organising the.... 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: investigate the role of classification in ordering and organising the diversity of life on Earth and use and develop classification tools including dichotomous keys.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- observing and identifying the similarities and differences of particular features within and between groups of organisms creating and modifying a dichotomous key to classify organisms into groups and groups within groups
- 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: investigate the role of classification in ordering and organising the diversity of life on Earth and use and develop classification tools including dichotomous keys
- E1: observing and identifying the similarities and differences of particular features within and between groups of organisms
- E2: creating and modifying a dichotomous key to classify organisms into groups and groups within groups
- E3: naming and classifying species using scientific conventions from the Linnaean hierarchical classification system, such as kingdom, phylum, class, order, family, genus, species
- E4: considering the reasons for classifying living things, such as identification and communication
- E5: examining how biological classification has changed over time through improvements in microscopy
- E6: using provided dichotomous keys to identify organisms surveyed on a field trip
- E7: investigating First Nations Australians’ systems of classifying living things and how these systems differ from those used by contemporary science (teaching context)
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.
