What students learn in AC9S10U07
This unit helps students build a clear, usable understanding of Patterns in synthesis, decomposition and displacement reactions and investigate 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: identify patterns in synthesis, decomposition and displacement reactions and investigate the factors that affect reaction rates.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- defining and representing synthesis, decomposition and displacement reactions using a variety of formats such as molecular models, diagrams, and word and balanced symbolic equations identifying reaction type and predicting the products
- 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: identify patterns in synthesis, decomposition and displacement reactions and investigate the factors that affect reaction rates
- E1: defining and representing synthesis, decomposition and displacement reactions using a variety of formats such as molecular models, diagrams, and word and balanced symbolic equations
- E2: identifying reaction type and predicting the products
- E3: investigating synthesis reactions such as reaction of metals with oxygen, formation of water and sodium chloride; decomposition reactions such as those used to extract metals; and displacement reactions such as metal and acid, neutralisation and precipitation
- E4: investigating the effect of a range of factors, such as temperature, concentration, surface area and catalysts, on the rate of chemical reactions
- E5: investigating chemical reactions employed by First Nations Australians in the production of substances such as acids and ethanol (teaching context)
- E6: investigating some of the chemical reactions and methods employed by First Nations Australians to convert toxic plants into edible food products (teaching context)
- E7: examining reactions that are used to produce a range of useful products
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.
