SACE Stage 2 Biology study plan

SACE Stage 2 Biology · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Science understanding & Practical and investigative skills

  • Map the Science Understanding syllabus into a one-page concept web linking cells, energy, inheritance, and evolution

  • Define and correctly use 30 core biological terms in context sentences, flagging any term you cannot define from memory

  • Practise two safe laboratory routines (aseptic transfer and serial dilution) and write the risk assessment for each

  • Identify the dependent, independent, and controlled variables in four sample experimental scenarios

Your checkpoint

A one-page concept web plus a glossary of 30 terms with context sentences and a 2 x risk-assessment template

Week 2

Science understanding & Practical and investigative skills

  • Explain photosynthesis and cellular respiration as coupled energy-transfer pathways using a labelled flow diagram

  • Calculate and interpret rates of reaction from tabulated data, including units and uncertainty

  • Design a controlled experiment testing one variable affecting enzyme activity, with a repeatable procedure

  • Distinguish accuracy, precision, reliability, and validity using your own experimental design as the example

Your checkpoint

A written experimental design (aim, hypothesis, variables, procedure, risk) for an enzyme-rate investigation

Week 3

Science understanding & Science inquiry skills

  • Model DNA structure, replication, and protein synthesis using a sequence of annotated diagrams

  • Predict offspring ratios from monohybrid and dihybrid crosses, including sex-linked and codominant cases

  • Construct and interpret pedigrees to infer genotypes and modes of inheritance

  • Evaluate the strength of evidence in three short genetics case studies

Your checkpoint

A worked problem set of 10 genetics questions with full reasoning and pedigree interpretations

Week 4

Science as a human endeavour & Science inquiry skills

  • Summarise how a named biological discovery changed scientific consensus, citing evidence and peer review

  • Analyse a bioethical issue (for example gene editing) by mapping stakeholders, benefits, risks, and regulatory responses

  • Evaluate the reliability of a secondary source by checking its methodology, sample, and funding disclosure

  • Write a 200-word evidence-based position statement with at least three cited sources

Your checkpoint

A 200-word evidence-based position statement on a bioethical issue with a reference list

Week 5

Science inquiry skills & Practical and investigative skills

  • Convert a research question into a testable hypothesis and select appropriate sampling and measurement methods

  • Process a raw dataset: calculate means, standard deviation, and a suitable statistical comparison

  • Graph data with correct axes, units, error bars, and captions, then describe the trend in two sentences

  • Identify three sources of error in a practical and propose a specific improvement for each

Your checkpoint

A complete data-analysis report on one dataset, including table, graph, statistics, and error discussion

Week 6

Science as a human endeavour & Science understanding

  • Trace how a scientific model (for example the fluid-mosaic membrane model) was revised as new evidence emerged

  • Compare scientific explanations with non-scientific claims using falsifiability and evidence criteria

  • Explain how collaboration and communication shape the direction of biological research

  • Connect one human-endeavour case study to the underlying Science Understanding concepts

Your checkpoint

A one-page case-study summary linking a scientific development to its evidence base and social context

Week 7

Practical and investigative skills & Science inquiry skills

  • Rehearse a full practical investigation from planning to conclusion under timed conditions

  • Write a discussion that links results to biological theory and acknowledges limitations

  • Peer-mark two sample investigation reports against a criterion sheet and justify each mark

  • Refine your own report after feedback, tracking every change made

Your checkpoint

A complete timed investigation report with a revision log showing responses to feedback

Week 8

Science understanding & Science as a human endeavour & Science inquiry skills & Practical and investigative skills

  • Synthesise all four domains into a revision matrix showing where each skill is assessed

  • Complete two full-length practice papers under exam conditions and mark them against the criteria

  • Target the three weakest topics identified by practice-paper errors with focused re-study

  • Write a personal exam checklist covering command words, data presentation, and ethics responses

Your checkpoint

Two marked practice papers with an error log and a one-page personal exam checklist

Week 4: Can solve monohybrid and dihybrid problems unaided and write an evidence-based ethical position with three cited sources

Week 6: Can analyse a dataset with correct statistics and graphs and explain one scientific development in its social and historical context

Week 8: Scores at least 75% on two full practice papers and has a written plan for every remaining weak topic
