Construct evidence-based arguments to support conclusions or evaluate claims and consider ethical issues and cultural protocols when using secondary information

1. Construct evidence-based arguments (E1)

Start with a testable hypothesis or claim. Decide whether the evidence supports, challenges or is insufficient to decide. Select relevant evidence, then explain the scientific reasoning that links it to the conclusion. Avoid saying a hypothesis is “proved” by one investigation.

2. Draw logical conclusions from evidence quality (E2)

Before making a broad conclusion, examine how the data were collected, sample size, uncontrolled variables, measurement quality, duration, missing evidence and uncertainty. A strong conclusion matches the scope of the evidence.

3. Determine source credibility (E3)

Credibility is not decided by one feature alone. Check authorship or responsible organisation, expertise, evidence, methods or references, publication date, publisher, purpose, possible bias, and whether claims can be traced to original evidence.

4. Megafauna extinction debate (E4)

Students investigate cultural, historical, archaeological, fossil and climate evidence used in debate about Australian megafauna extinction. The goal is not to memorise a single cause. Compare what each line of evidence supports, where it is limited, and whether conclusions are local or broad.

Balanced conclusion: evidence may support several interacting explanations; uncertainty should be acknowledged rather than hidden.

5. Ethical use and commercialisation of First Nations knowledge (E5)

First Nations knowledges are diverse, place-based and culturally governed. Responsible research or commercial use should identify the relevant knowledge holders and follow appropriate cultural authority, consent, attribution, intellectual-property arrangements and benefit-sharing. Do not assume information is free to use simply because it appears in a secondary source.
