HSC Science Extension study plan

HSC Science Extension · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

The Foundations of Scientific Thinking

  • Define scientific thinking and distinguish it from pseudoscience and non-science using at least four explicit criteria

  • Compare inductive, deductive and abductive reasoning and construct one valid example of each

  • Explain how paradigms and theory change shape what counts as evidence, citing two historical episodes in your own words

  • Map the structure of Domain 1 into a concept diagram that links observation, hypothesis, theory and law

Your checkpoint

A one-page concept diagram of Domain 1 plus a 400-word written comparison of the three reasoning types with worked examples

Week 2

The Foundations of Scientific Thinking

  • Evaluate the role of peer review, replication and reproducibility in establishing scientific claims

  • Analyse at least two case studies of scientific error or fraud and identify the failure point in each

  • Distinguish correlation from causation and identify confounds in three supplied scenarios

  • Summarise the ethical frameworks governing research conduct, including consent, animal ethics and data integrity

Your checkpoint

A 600-word critical analysis of two case studies of scientific error, naming the specific methodological or ethical failure in each

Week 3

The Foundations of Scientific Thinking & The Scientific Research Proposal

  • Identify a researchable question in your own field and justify why it is significant and feasible

  • Critique three published abstracts to extract the implicit research question, hypothesis and variables

  • Draft a testable hypothesis with clearly operationalised independent and dependent variables

  • Write a first draft of the literature review structure with at least eight credible sources located

Your checkpoint

A 700-word draft research question and hypothesis statement with an annotated bibliography of eight sources

Week 4

The Scientific Research Proposal

  • Design a methodology that matches your research question, justifying qualitative, quantitative or mixed approach

  • Specify sampling strategy, sample size rationale and inclusion criteria

  • Construct a data collection instrument or protocol and pilot it with two volunteers

  • Draft a risk assessment and ethics application outline covering consent, confidentiality and data storage

Your checkpoint

A complete methodology section of 900 words with sampling plan, instrument draft and ethics outline

Week 5

The Scientific Research Proposal & The Data, Evidence and Conclusions

  • Build a realistic timeline with dependencies and contingencies for the proposed research

  • Select appropriate statistical or analytical techniques and justify each against your data type

  • Identify potential sources of bias and error and state a mitigation for each

  • Prepare a full research proposal ready for peer feedback

Your checkpoint

A submitted full research proposal of 1500 words including timeline, analysis plan and bias mitigation table

Week 6

The Data, Evidence and Conclusions

  • Clean and code a practice dataset and document every transformation decision

  • Apply descriptive statistics and produce appropriate visualisations for the dataset

  • Interpret a p-value, confidence interval and effect size correctly without overclaiming

  • Distinguish statistical significance from practical significance using a worked example

Your checkpoint

An analysis workbook with cleaned dataset, summary statistics, three labelled figures and a 300-word interpretation

Week 7

The Data, Evidence and Conclusions & The Scientific Research Report

  • Draw conclusions that are proportionate to the evidence and explicitly state limitations

  • Structure a discussion that links findings back to the literature and identifies further research

  • Draft results and discussion sections using precise, non-causal language where causality is not established

  • Peer-review a classmate's draft using a structured criteria checklist

Your checkpoint

A 1000-word results and discussion draft plus a completed peer-review checklist for one classmate

Week 8

The Scientific Research Report

  • Assemble the full research report to the required structure and referencing convention

  • Edit for concision, remove unsupported claims and verify every citation against its source

  • Prepare and rehearse a short oral defence of the research decisions made

  • Complete a final self-audit against the marking criteria for all four domains

Your checkpoint

A final research report of 2500-3000 words with verified reference list and a rehearsed five-minute defence outline

Milestones

Week 2: Can explain paradigm change, replication and research ethics without notes, scoring at least 80% on a self-made Domain 1 quiz

Week 4: Research question, hypothesis and methodology are internally consistent and approved by a mentor or peer reviewer

Week 6: Practice dataset fully analysed with correct interpretation of effect size and confidence intervals

Week 8: Full report submitted with all citations verified and a completed self-audit against the marking criteria
