Curriculum content descriptions

plan and conduct reproducible investigations to answer questions and test hypotheses, including identifying variables and assumptions and, as appropriate, recognising and managing risks, considering ethical issues and recognising key considerations regarding heritage sites and artefacts on Country/Place (AC9S7I02)

Elaborations
  • comparing the method with the hypothesis and examining the reasonableness of the method for testing that hypothesis
  • discussing why it is important to identify variables and assumptions when planning an investigation
  • examining the features of reproducible investigations, constructing methods and reviewing other students’ methods
  • identifying assumptions relating to variables that are assumed to be constant, such as ambient temperature, properties of materials used or purity of substances
  • identifying risks to themselves and others in investigations and considering actions that can be taken to avoid or manage those risks
  • considering ethical issues relating to interactions with living things
  • recognising state and territory laws as they relate to First Nations Australians’ heritage sites and artefacts
  • collaborating with First Nations Australians communities and organisations to conduct investigations about ecosystems, ensuring mutually beneficial outcomes
  • acknowledging and recognising First Nations Australians’ artefacts and heritage sites, such as human stonework and scatter sites in comparison with rocks changed by natural processes, and understanding not to harm or disturb sites
General capabilities
