AC9S9I01

Elaborations

• AC9S9I01_E1discussing what is needed for a question to be investigable or a prediction to be reasoned
• AC9S9I01_E2generating investigable questions about the relationships between human body systems and everyday events, such as: ‘How does the intensity of exercise affect heart rate and breathing rate?’
• AC9S9I01_E3developing investigable questions to explore an explanatory model, such as: ‘How is sound wave transfer affected by the density of the medium through which it travels? What causes our body temperature to rise when we are ill?’
• AC9S9I01_E4discussing why a scientific hypothesis has to be able to be supported or refuted through evidence
• AC9S9I01_E5proposing a hypothesis to test an identified relationship, such as: ‘If objects of different temperatures are placed in contact, heat energy will transfer from an object of higher temperature to an object of lower temperature until both objects reach the same temperature’
