This page shows the current Skill Align science curriculum practice coverage for Years 7 to 9. The science structure follows ACARA-V9 and uses public ACARA strand and sub-strand names across Year 7, Year 8, and Year 9.

Curriculum codes only appear when a subtopic has a clear one-to-one ACARA-V9 mapping. Many science entries stay uncoded because one public strand or sub-strand can cover several curriculum references.

Science Topics and Subtopics

Years 7, 8, and 9 only

Topic	Year 7	Year 8	Year 9
Science as a human endeavour	1. Nature and development of science • Use examples showing that scientific explanations can change when new evidence, improved observations or different perspectives are considered.• Keep focus on school-level observations, models and evidence rather than history-of-science trivia. 2. Use and influence of science • Use everyday and community contexts to show how science and technologies affect people, resources and the environment.• Keep questions evidence-based and avoid opinion-only prompts.	1. Nature and development of science • Use how models, evidence and new observations refine scientific understanding over time.• For harder questions, ask students to evaluate how new evidence changes a model or explanation in resource, energy, health or environmental contexts. 2. Use and influence of science • Use how science and technologies influence resource, energy, health or environmental decisions.• Keep reasoning objective and evidence-based, with one best answer supported by the supplied information rather than personal opinion.	1. Nature and development of science • Use how evidence, models and scientific explanations develop over time, including how new evidence changes confidence in explanations.• For harder questions, ask students to evaluate model strengths, limitations or evidence quality without drifting into senior science. 2. Use and influence of science • Use social, environmental and technological decision-making contexts informed by science.• Keep the best answer grounded in consequence/evidence reasoning rather than personal preference.
Science inquiry	1. Communicating text graph • Use clear scientific vocabulary, labelled tables or graphs, short evidence-based statements and appropriate formats for findings.• Prefer best-wording, best-conclusion or best-presentation choices. 2. Evaluating • Check whether a method was fair, the data were sufficient, and the conclusion matched the evidence.• Use simple improvements and limitations rather than extended critique. 3. Planning and conducting • Use fair tests, simple controlled variables, safe practical method choices and appropriate equipment selection.• Prefer objective method-selection questions over extended practical reports. 4. Processing, modelling and analysing text graph • Use tables, simple graphs, classification tools, particle diagrams, force diagrams and clear patterns in data.• Keep interpretation straightforward and evidence-based. 5. Questioning and predicting • Use testable questions and simple predictions based on patterns or prior observations.• Keep scenarios tied to school experiments, classification tasks, force investigations, separation tasks or familiar fieldwork.	1. Communicating text graph • Use precise scientific language, clear graph/table presentation and evidence-based conclusions.• Prefer format, wording, claim-evidence or interpretation choices grounded in data and audience needs. 2. Evaluating • Use reliability, fairness, validity, limitations and method improvement at a school-investigation level.• Keep evaluation evidence-based rather than open-ended, and ask what change would most improve the investigation. 3. Planning and conducting • Use variables, fair tests, repeated trials, safer method choices and appropriate equipment selection.• Prefer method-design choices with one clearly best answer and visible links to reliability, fairness or validity. 4. Processing, modelling and analysing text graph • Use tables, graphs, simple models and clear data patterns to identify trends, compare results or support conclusions.• Allow slightly denser data than Year 7, but keep the conclusion unambiguous and evidence-based. 5. Questioning and predicting • Use more specific testable questions, predictions and hypotheses linked to variables, patterns or prior observations.• Keep the scientific context explicit and ask whether the question can be investigated fairly.	1. Communicating text graph • Use evidence-based scientific communication with clear claims, data, reasoning, limitations and audience-appropriate wording.• Prefer concise communication choices that accurately represent findings and uncertainty. 2. Evaluating • Use validity, reliability, evidence quality, anomalous data, uncertainty and justified method critique.• Keep the evaluation objective and tied to the given investigation or claim. 3. Planning and conducting • Use controlled variables, fair tests, fieldwork, reliability, validity, safety and improved method design.• Prefer one clearly best investigation design or variable-control choice. 4. Processing, modelling and analysing text graph • Use moderate data density, graphs, tables, models, anomalous data and pattern reasoning.• Ask students to connect evidence to a supported conclusion or explain why a model fits the data. 5. Questioning and predicting • Use causal hypotheses and predictions linked to controlled variables, fieldwork, fair tests or model-based investigations.• Keep the question focused on one clearly testable relationship.
Science understanding	1. Biological sciences text diagram graph • Use classification of living things with observable features, simple dichotomous keys, food chains, food webs, ecosystem roles, matter and energy flow, and population change in familiar environments.• For harder questions, include classification tools, simple ecosystem diagrams, food-web interpretation, and evidence-based predictions about population change. 2. Chemical sciences • Use the particle model to explain solids, liquids, gases, changes of state, diffusion, density-related particle reasoning, pure substances, mixtures, and separation techniques linked to observable properties.• For harder questions, include particle diagrams, separation-method choice, data from heating/cooling or separation tasks, and explanation of observations using the particle model. 3. Earth and space sciences text diagram • Use predictable phenomena explained by the relative positions of Earth, Sun and Moon, including day/night, seasons where appropriate, phases, eclipses, tides at a simple level, and observational evidence.• Keep astronomy reasoning Year 7 appropriate and avoid advanced orbital mechanics. 4. Physical sciences text diagram • Use balanced and unbalanced forces to explain changes in motion, gravity, contact and non-contact force examples, simple force diagrams and everyday motion contexts.• For harder questions, include force diagrams, cause-and-effect motion reasoning, and interpretation of simple experimental observations.	1. Biological sciences • Use cells, specialised structures, microscopes, organelles, and how structure supports function in cells, tissues, organs and systems.• For harder questions, include cell diagrams, organ-system diagrams, structure-function reasoning and simple biological data. 2. Chemical sciences text diagram • Use elements, compounds, mixtures, names, symbols, formulas, simple particle representations, physical changes, chemical changes and observable indicators of chemical reactions.• For harder questions, include particle diagrams, reaction evidence, formula interpretation and classification of changes. 3. Earth and space sciences • Use plate tectonics to explain global patterns such as earthquakes, volcanoes, mountain building and continental movement.• For harder questions, include map-style evidence, tectonic boundary reasoning, geological timescales at an accessible level and evidence-based geological explanation. 4. Physical sciences text graph • Use kinetic and potential energy, energy transfer, energy transformations, conservation ideas, efficiency and electricity generation or energy-source contexts.• For harder questions, include energy-flow diagrams, simple calculations if supported, graph/table interpretation and evaluation of energy transfers.	1. Biological sciences • Use body responses to stimuli, coordination, nervous and endocrine systems at Year 9 level, feedback and regulation, reproduction, sexual and asexual reproduction, species survival and variation.• For harder questions, include feedback diagrams, stimulus-response scenarios, reproduction comparisons, and evidence-based biological explanation. 2. Chemical sciences text • Use atomic structure, simple chemical equations, conservation of mass, reactants and products, synthesis/decomposition/displacement style reaction patterns where appropriate, and introductory acids and bases.• For harder questions, include balanced equation interpretation, reaction evidence, pH-style observations, particle/atomic models and data interpretation without senior chemistry depth. 3. Earth and space sciences • Use the carbon cycle and interactions between atmosphere, biosphere, hydrosphere and geosphere.• For harder questions, include carbon-cycle diagrams, environmental data, system interactions, cause-effect reasoning and evidence-based climate/environment explanation. 4.
