develop investigable questions, reasoned predictions and hypotheses to explore scientific models, identify patterns and test relationships (AC9S8I01)

Elaborations
  • discussing what is meant by a causal relationship and examining how causation is different from correlation
  • developing investigable questions to test causal relationships, such as: ‘How does the concentration of a salt solution affect plant cells? How does the amount of sunlight affect the amount of electricity produced by a solar cell?’
  • developing investigable questions to explore scientific models, such as: ‘How do the shapes of the continents support the theory of plate tectonics?’
  • predicting what will happen when conditions change in a given scenario or phenomenon, such as: ‘When materials of less resistance are used to transfer electricity there will be less heat energy produced’
  • formulating hypotheses such as: ‘An earthquake of greater magnitude will cause more damage because there is more energy transferred’
