Science understanding
Cells are the basic units of living things. Compare plant and animal cells, connect organelle structure to function, and distinguish real microscope evidence from…
ExampleWhy are cells described as the basic units of living things?
recognise cells as the basic units of living things, compare plant and animal cells, and describe the functions of specialised cell structures and organelles
Science understanding
Specialised structures enable functions. Trace organisation from cell to tissue to organ to organ system, then explain how plant and animal systems keep the whole…
ExampleWhich sequence shows increasing levels of organisation in a multicellular organism?
analyse the relationship between structure and function of cells, tissues and organs in a plant and an animal organ system and explain how these systems enable survival of the individual
Science understanding
Connect plate motion to geological features and hazards, then use several independent lines of evidence to explain why plate tectonics became the accepted scientific…
ExampleA world map shows most earthquake epicentres forming narrow belts around the Pacific Ocean and along mid-ocean ridges. What is the best explanation?
investigate tectonic activity including the formation of geological features at divergent, convergent and transform plate boundaries and describe the scientific evidence for the theory of plate tectonics
Science understanding
Use texture, layers, crystals, fossils and foliation as evidence for formation, then connect rock-cycle processes and timescales to useful properties and human choices
ExampleA rock sample has clear layers and a small shell fossil. Which rock group does this evidence most strongly support?
describe the key processes of the rock cycle, including the timescales over which they occur, and examine how the properties of sedimentary, igneous and metamorphic rocks reflect their formation and influence their use
Science understanding
Classify energy as kinetic or potential, trace how it moves and changes form through simple systems, and account for useful and less-useful outputs without saying energy…
ExampleWhich example is best classified as kinetic energy?
classify different types of energy as kinetic or potential and investigate energy transfer and transformations in simple systems
Science understanding
Classify matter from particle evidence, then choose the representation—particle model, symbol, formula or composition—that communicates the scientific information you…
ExampleModel A contains only identical unbonded blue atoms. What does it represent?
classify matter as elements, compounds or mixtures and compare different representations of these, including 2-dimensional and 3-dimensional models, symbols for elements and formulas for molecules and compounds
Science understanding
Decide whether a new substance formed using multiple observations, then interpret temperature changes as evidence of energy transfer in chemical reactions
ExampleWhich observation is strongest evidence that a gas has formed during a chemical reaction?
compare physical and chemical changes and identify indicators of energy change in chemical reactions
Science as a human endeavour
Scientific knowledge is revised when reliable new evidence, improved technologies or different perspectives reveal limits in an earlier explanation
ExampleEarly light microscopes allowed scientists to see cells that were invisible to the naked eye. What best explains how this changed scientific knowledge?
explain how new evidence or different perspectives can lead to changes in scientific knowledge
Science as a human endeavour
Science is evidence-based, but people and communities influence which questions are asked, whose knowledge is recognised and how research is designed and interpreted
ExampleWhy can unequal access to universities and laboratories influence the development of scientific knowledge?
investigate how cultural perspectives and world views influence the development of scientific knowledge
Science as a human endeavour
Scientific responses can reduce risks or solve part of a problem, but responsible evaluation weighs benefits, limitations, trade-offs and impacts across society and the…
ExampleA transplant service has one donor liver and two medically suitable patients. Why is this an ethical issue rather than only a medical one?
examine how proposed scientific responses to contemporary issues may impact on society and explore ethical, environmental, social and economic considerations
Science as a human endeavour
Science communication connects evidence with audiences. Clear, accurate and transparent messages can inform viewpoints, behaviour, community policy and regulation without…
ExampleA national health campaign explains how organ donation works, corrects common myths and asks families to discuss consent. Why is this approach useful?
explore the role of science communication in informing individual viewpoints and community policies and regulations
Science inquiry
Good investigations begin with questions that evidence can answer. Patterns and models support reasoned predictions and testable hypotheses—not guesses
ExampleStudents who study longer tend to score higher on tests. What would strengthen a causal claim that study time affects scores?
develop investigable questions, reasoned predictions and hypotheses to explore scientific models, identify patterns and test relationships
Science inquiry
A reproducible investigation records enough detail for another investigator to repeat the method and obtain comparable evidence safely and responsibly
ExampleStudents investigate how salt concentration affects osmosis in potato cells but use different potato varieties in each trial. What is the main problem?
plan and conduct reproducible investigations to answer questions and test hypotheses, including identifying variables and assumptions and, as appropriate, recognising and managing risks, considering ethical issues and recognising key considerations regarding heritage sites and artefacts on Country/Place
Science inquiry
Useful data depends on suitable equipment, correct technique, justified digits, clear units and enough repeated measurements to reveal variation
ExampleA student needs 25.0 mL of water. Which equipment is most appropriate?
select and use equipment to generate and record data with precision, using digital tools as appropriate
Science inquiry
A useful representation matches the data and purpose, processes values correctly and makes patterns visible without hiding limitations
ExampleA student wants an average of B2:B6. Which formula is best?
select and construct appropriate representations, including tables, graphs, models and mathematical relationships, to organise and process data and information
Science inquiry
Data analysis describes what most values do, investigates departures from the pattern and keeps conclusions within the available evidence
ExampleA student says higher drop height causes deeper indentation. When is this conclusion most justified?
analyse data and information to describe patterns, trends and relationships and identify anomalies
Science inquiry
A strong evaluation names a specific limitation, explains how it affects evidence and proposes a targeted check or improvement
ExampleReaction tablets from two brands are compared as if they are identical. Why is this a problem?
analyse methods, conclusions and claims for assumptions, possible sources of error, conflicting evidence and unanswered questions
Science inquiry
A scientific argument links a precise claim to relevant evidence and reasoning, acknowledges limits and handles secondary information responsibly
ExampleA student claims Brand X batteries last longer after one trial. Why is the evidence weak?
construct evidence-based arguments to support conclusions or evaluate claims and consider any ethical issues and cultural protocols associated with using or citing secondary data or information
Science inquiry
Scientific communication can change vocabulary, structure and medium for an audience while preserving evidence, units, uncertainty and meaning
ExampleWhich sentence best reports a result in formal scientific language?
write and create texts to communicate ideas, findings and arguments for specific purposes and audiences, including selection of appropriate language and text features, using digital tools as appropriate
