Curriculum content descriptions

Scientific understanding, including models and theories, is contestable and is refined over time through a process of review by the scientific community (ACSHE157)

Elaborations
  • investigating the historical development of models of the structure of the atom
  • investigating how the theory of plate tectonics developed, based on evidence from sea-floor spreading and occurrence of earthquakes and volcanic activity
  • considering how ideas about disease transmission have changed from medieval time to the present as knowledge has developed
  • investigating the work of scientists such as Ernest Rutherford, Pierre Curie and Marie Curie on radioactivity and subatomic particles
  • investigating how models can be used to predict the changes in populations due to environmental changes, such as the impact of flooding or fire on rabbit or kangaroo populations
General capabilities
  • Ethical understanding Ethical understanding
