Resources
  • Identify the finite nature of the minerals and resources extracted in Australia

  • Investigate the products produced from Australian minerals and resources

  • Explain how Aboriginal and Torres Strait Islander Peoples used minerals and resources for a wide range of purposes

  • Evaluate the environmental impact of extracting and using a named resource and document findings in a written scientific report

Bonding
  • Use valency to describe the number of electrons an atom needs to gain, lose or share to achieve a stable electron configuration

  • Explain noble gas configuration and identify that it occurs during chemical bonding

  • Describe types of chemical bonds, including ionic, covalent and metallic bonds

  • Use models to describe the formation of cations and anions

  • Recognise that some elements exist as diatomic molecules

  • Construct chemical formulas of some common ionic compounds and covalent molecules

  • Conduct an investigation to observe and compare the physical and chemical properties of ionic, covalent and metallic substances, and explain how these relate to their uses

Chemistry of organic compounds
  • Distinguish between organic and inorganic compounds

  • Describe how hydrocarbons can be separated from crude oil and identify the uses of these products

  • Use International Union of Pure and Applied Chemistry (IUPAC) nomenclature to name simple organic compounds

  • Identify and reproduce the structure of simple alkanes C1–C8

  • Describe the differences between complete and incomplete combustion reactions of hydrocarbons, and use examples from everyday applications to compare the products of the chemical reaction and amount of energy released

  • Research the uses of hydrocarbon compounds and how this has changed over time

Polymers
  • Identify the raw materials used to make polymers

  • Investigate and describe the properties of a range of polymers

  • Determine the quantity and types of polymers found in the environment by undertaking a physical survey of the local area

  • Conduct an investigation to determine the biodegradability of different packaging materials

  • Investigate case studies to explain the effect of bioaccumulation of microplastics in the environment

Materials in context
  • Assess the environmental impacts of materials that are used as alternatives to those derived from crude oil
