Content descriptor develop investigable questions, reasoned predictions and hypotheses to test relationships and develop explanatory models

Elaborations

• • Elaboration discussing what is needed for a question to be investigable or a prediction to be reasoned
• • Elaboration generating 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?’
• • Elaboration developing 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?’
• • Elaboration discussing why a scientific hypothesis has to be able to be supported or refuted through evidence
• • Elaboration proposing 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’
