What students learn in AC9S10U03
This unit helps students build a clear, usable understanding of How the big bang theory models the origin and evolution.... 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: describe how the big bang theory models the origin and evolution of the universe and analyse the supporting evidence for the theory.
- Use concrete examples, pictures, oral explanation and short written responses before moving to independent practice.
- describing the major components of the universe using appropriate scientific terminology and units including astronomical units, scientific notation and light-years constructing a timeline to show major changes in the universe which are thought to have occurred from the Big Bang until the formation of the major components such as stars and galaxies
- 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: describe how the big bang theory models the origin and evolution of the universe and analyse the supporting evidence for the theory
- E1: describing the major components of the universe using appropriate scientific terminology and units including astronomical units, scientific notation and light-years
- E2: constructing a timeline to show major changes in the universe which are thought to have occurred from the Big Bang until the formation of the major components such as stars and galaxies
- E3: examining how stars’ light spectra and brightness is used to identify compositional elements of stars, their movements and their distances from Earth
- E4: explaining how each different type of evidence, such as cosmic microwave background radiation, red or blue shift of galaxies, Edwin Hubble’s observations and proportion of matter in the universe, provides support for the acceptance of the big bang theory
- E5: researching First Nations Australians’ knowledges of celestial bodies and explanations of the origin of the universe (teaching context)
- E6: identifying the different technologies used to collect astronomical data and the types of data collected
- E7: exploring recent advances in astronomy, including the Australian Square Kilometre Array Pathfinder, and astrophysics, such as the discovery of gravitational waves, dark matter and dark energy; and identifying new knowledge which has emerged

- 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.
