What students learn in AC9S4U01
This unit helps students build a clear, usable understanding of Explain the roles and interactions of consumers, producers and decomposers.... 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: explain the roles and interactions of consumers, producers and decomposers within a habitat and how food chains represent feeding relationships.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- describing how animals, including humans, obtain their food from plants and other animals observing living things in a local habitat and categorising them as producers, consumers or decomposers
- Finish with mixed questions so students must choose the correct strategy rather than copy the last example.

- E3: researching the different types of decomposers and their importance within a habitat
- E4: representing feeding relationships of producers and consumers as a food chain and comparing food chains across different habitats
- E5: recognising how First Nations Australians perceive themselves as being an integral part of the environment (teaching context)
- E6: investigating the impact of introduced predators such as foxes on small mammal species in Australia

- 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.
