Content descriptor describe how the big bang theory models the origin and evolution of the universe and analyse the supporting evidence for the theory

Elaborations

• • Elaboration describing the major components of the universe using appropriate scientific terminology and units including astronomical units, scientific notation and light-years
• • Elaboration 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
• • Elaboration examining how stars’ light spectra and brightness is used to identify compositional elements of stars, their movements and their distances from Earth
• • Elaboration 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
• • Elaboration researching First Nations Australians’ knowledges of celestial bodies and explanations of the origin of the universe
• • Elaboration identifying the different technologies used to collect astronomical data and the types of data collected
• • Elaboration 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
