• 2 determining the reproducibility of a field investigation using survey techniques that seek to answer a question such as: ‘How much traffic passes the school during a designated period of time?’
• 3 identifying possible sources of error in methods then examining if further testing or extra variable control is needed
• 4 identifying the potential hazards of chemicals or biological materials and processes used in experimental investigations and identifying how these should be addressed
• 5 discussing the ethical and social issues involved in the care and use of animals for scientific purposes before starting an investigation involving animals
• 6 recognising First Nations Australians’ heritage laws and public responsibilities to report new sites or artefacts, and developing awareness of the consequences for disturbing heritage sites on, above or below the land surface, or in waters
