Stage 5 Science: Every NSW Syllabus Outcome, Explained

Stage 5 Science in the NSW syllabus is 19 outcomes, SC5-DA2-01 through SC5-WS-08, covering Years 9 and 10. Eleven are content outcomes across eight focus areas, and eight are Working scientifically outcomes.

Two things are worth knowing before you plan. Unlike Stage 5 Mathematics, where 23 of the 41 outcomes are Path outcomes and students are streamed, Stage 5 Science does not split into Core and Path at all. Every outcome is compulsory for every student. And as at Stage 4, NESA publishes each Working scientifically outcome against the focus areas that develop it, which no other Australian framework does.

This guide covers all 19 outcomes, the mapping table, how the skills escalate from Stage 4, what NSW carries that the national curriculum does not, the four outcomes that decide senior science, a two-year teaching order and six checks.

How Stage 5 Science is built

Eight content focus areas carry eleven outcomes, because three of them hold two: Genetics and evolutionary change, Reactions, and Waves and motion. That is a change from Stage 4, where every focus area had exactly one outcome, and it tells you where the syllabus expects the extra depth.

The eight focus areas are Data science 2, Disease, Energy, Environmental sustainability, Genetics and evolutionary change, Materials, Reactions, and Waves and motion. Read that list against Stage 4 and the shape of the change is clear: the descriptive focus areas (Cells and classification, Observing the Universe, Living systems) are gone, and what replaces them is mechanism and consequence.

As at Stage 4, there is no separate Science as a Human Endeavour strand. NSW embeds that thinking in the content outcomes instead, and at Stage 5 it does so much more strongly: SC5-EGY-01 asks students to evaluate energy use on ethical and sustainability grounds, SC5-ENV-01 asks them to analyse the impact of human activity, and SC5-DA2-01 asks them to assess how data is used in evidence-based decisions and when verifying claims. Three of the eleven content outcomes are evaluative rather than explanatory.

The mapping NESA gives you

Each Working scientifically outcome is published against the focus areas it should be developed through. This is the same planning asset the Stage 4 syllabus provides, and it is worth using the same way: it tells you which units need to carry laboratory time and which need to carry analysis time.

The distribution is more lopsided than at Stage 4 and it is highly informative. Reactions carries four Working scientifically outcomes, all of them the practical ones: tools, hypotheses, designing investigations and following procedures. Data science 2 carries three, all of them analytical: drawing conclusions, evaluating solutions and communicating arguments. NESA is telling you that Reactions is where students learn to do experiments and Data science 2 is where they learn to reason about results. Plan those two units accordingly, and do not put your laboratory time into Disease or Environmental sustainability, which carry no practical Working scientifically outcomes at all.

How the skills escalate from Stage 4

The eight Working scientifically outcomes cover the same eight jobs at both stages, and the wording changes in a consistent direction: identification becomes selection, and description becomes evaluation.

• Stage 4 identifies questions and makes predictions; Stage 5 develops questions and hypotheses. A prediction says what will happen; a hypothesis says what will happen and proposes why, and it has to be testable.
• Stage 4 plans safe and valid investigations; Stage 5 designs safe, ethical, valid and reliable ones. Two words are added. Reliable is about consistency on repetition, which is separate from validity, and ethical becomes an explicit design requirement rather than a safety afterthought.
• Stage 4 identifies problem-solving strategies and proposes solutions; Stage 5 selects suitable strategies and evaluates proposed solutions. The assessable act moves from generating an option to judging between options.
• Stage 4 communicates scientific concepts and ideas; Stage 5 communicates scientific arguments with evidence. That is the largest single jump in the strand: the output is no longer an explanation, it is a case.

Stage 4 also asks for observations, where Stage 5 asks for accurate observations, and Stage 5 adds selecting the tools rather than using the ones supplied. Taken together, Stage 5 Working scientifically is about judgement: which question, which method, which tool, which solution, which evidence.

What NSW carries that the national curriculum does not

• Disease is a focus area. SC5-DIS-01 covers how understanding the causes of disease is used to prevent and manage its spread. The national curriculum has no disease content in Year 9 or Year 10 at all. Victoria does carry it, so on this point the national curriculum is the outlier among the three Australian frameworks rather than NSW being unusual.
• Data science continues as its own focus area. SC5-DA2-01 asks students to assess the use of scientific knowledge and data in evidence-based decisions and when verifying the legitimacy of claims. That last clause is claim-checking as curriculum content, and it is the most directly useful outcome in the syllabus for life outside school. Neither the national curriculum nor Victoria has a data science strand in Science.
• Environmental sustainability and Energy are evaluative outcomes. SC5-ENV-01 analyses the impact of human activity on the natural world, and SC5-EGY-01 evaluates current and alternative energy use on ethical and sustainability grounds. The national curriculum approaches climate through a model of energy flow between Earth’s spheres, which is a mechanism descriptor; NSW asks for a judgement.

Running the other way, the national curriculum carries cosmology at Year 10 in the big bang theory and its evidence, and NSW has no Stage 5 astronomy: Observing the Universe was a Stage 4 focus area and does not return. If you are teaching a NSW student who is interested in astronomy, Stage 5 is not where the syllabus will meet them.

The 19 outcomes at a glance

Reading the codes

The pattern is SC + stage number + focus area abbreviation + number, so SC5-GEV-02 is Stage 5, Genetics and evolutionary change, outcome 2. Three focus areas hold two outcomes and the rest hold one.

Note what these codes do not carry. In Stage 5 Mathematics every outcome has a C or a P for Core or Path, and 23 of 41 are Path, so students are streamed inside the stage. Science has no such letter, and neither does English. Of the three subjects, only Mathematics streams at Stage 5, which surprises parents who assume streaming works the same way across a timetable. Our guide to how the NSW syllabuses are structured covers stages, outcomes and the Core and Path system, and Stage 4 Maths shows where that split begins.

The four outcomes that decide senior science

SC5-GEV-01: individuals do not evolve

The misconception: that organisms change during their lives in response to need and pass those changes on. It is the intuitive theory almost everybody constructs, it survives instruction readily, and it hides behind a correct definition a student can still recite.

What you will see: explanations built on need and effort. Animals developed thicker fur because it got colder; bacteria became resistant because they got used to the antibiotic. The tell is the verb: a correct explanation says some individuals already had the trait, and an incorrect one says the population developed or acquired it. Two related errors follow: evolution read as improvement, so later organisms are treated as better rather than as differently suited, and survival of the fittest read as the strongest surviving rather than the best matched to the current environment.

The fix: put variation first and never let a selection story start without it. Require a fixed four-part structure: variation already existed, the environment changed or differed, some variants survived and reproduced more, and the proportion in the population shifted. The need-based version cannot be written into that structure, which is the point. Antibiotic resistance is the best worked case because the timescale is short enough to be real and the mechanism is unambiguous. Then use SC5-GEV-02 to close the loop, since DNA transmitting heritable characteristics is what makes the variation heritable in the first place, and the two outcomes are much stronger taught together than apart.

SC5-WS-03: valid, reliable and ethical are three separate questions

The misconception: that a good investigation is a careful one, so all three words mean roughly the same thing and more repeats improve all of them. Stage 4 introduced valid; Stage 5 adds reliable and ethical to the same outcome, and if the distinctions are not taught, students absorb them as synonyms for thorough.

What you will see: an investigation run five times with tightly clustered results, reported as valid on that basis, that measured the wrong quantity throughout. Consistency is reliability and says nothing about whether the right thing was measured. The reverse also appears: a well-designed investigation run once, dismissed as invalid because there were no repeats. And ethical is routinely reduced to safety, so a student ticks a risk assessment and believes the ethical requirement is met.

The fix: ask three questions in a fixed order and never merge them. Does the method measure what we claim (valid)? Would repeating it give the same result (reliable)? Is it acceptable to do (ethical)? Only the second is about repeats. The most efficient teaching device is a method that is highly reliable and clearly invalid, built deliberately: timing a reaction by when the fizzing sounds like it has stopped gives beautifully consistent, meaningless data. For the ethical question, separate it from safety with a case where nothing is dangerous and something is still not acceptable, such as an investigation involving living organisms or personal data from classmates. Because SC5-WS-04 repeats all four words, this is assessed twice, and Reactions is the focus area NESA attaches both to.

SC5-DA2-01: verifying a claim is a method, not an instinct

The misconception: that checking a claim means deciding whether it sounds plausible or whether you trust the source. The outcome asks students to assess how knowledge and data are used in evidence-based decisions and in verifying legitimacy, which is a procedure that can be taught, and NSW is the only Australian framework that asks for it in Science.

What you will see: two failure modes that look opposite and are the same. Uncritical acceptance of a claim because it has a number or a graph attached, and blanket dismissal of anything from a source the student distrusts. Neither involves checking anything. In between sits the most common one: a student who says a claim needs evidence and cannot say what evidence would settle it.

The fix: make verification a checklist that runs the same way every time. What exactly is being claimed, and is it specific enough to be checked? What data would settle it? Where did the data come from and who collected it? Does the data actually support the claim, or a narrower one? Has anyone else found the same thing? That sequence is teachable and it works on anything, which is the point. Use real claims with real numbers rather than invented ones, and include claims that turn out to be well supported, because a lesson where everything is debunked teaches cynicism rather than method. NESA attaches SC5-WS-06, SC5-WS-07 and SC5-WS-08 to this focus area, so drawing conclusions, evaluating solutions and arguing from evidence all belong here.

SC5-WAM-02: the reaction force acts on the other object

The misconception: that action and reaction forces cancel, so nothing should ever accelerate. It follows directly from the third law being taught as “every action has an equal and opposite reaction” without the clause that matters: the two forces act on different objects, and cancelling only happens between forces on the same object.

What you will see: a student who can state the third law and cannot explain how a horse pulls a cart, since the cart pulls back equally. In force diagrams, the action and reaction pair drawn on the same object, which is the visible form of the same error. And the first-law residue from Stage 4, where a moving object is drawn with a forward arrow because it is moving.

The fix: never state the third law the short way. Require every pair to be written as a sentence naming both objects and both directions, so the pair cannot be drawn on one diagram. Then use the horse and cart deliberately as the puzzle rather than avoiding it, because resolving it is the proof the student has the idea: the cart accelerates because of the forces on the cart, and the horse’s backward pull acts on the horse. Keep the every-arrow-needs-a-named-source rule from Stage 4 running throughout. NESA attaches SC5-WS-04 and SC5-WS-05 to Waves and motion, so this is a unit expected to carry real practical and data work rather than being taught from diagrams alone.

What students need to arrive with

Stage 5 assumes Stage 4 is finished, and three prerequisites carry most of the weight. SC4-PRT-01 (periodic table and atomic structure) underpins both Reactions outcomes and SC5-MAT-01, since what a material does follows from what it is made of. SC4-FOR-01 (effects of forces) underpins SC5-WAM-02, and the motion misconception it addresses will still be present in a proportion of students. And SC4-WS-03 (planning safe and valid investigations) underpins SC5-WS-03, which adds reliable and ethical to the same act.

SC4-DA1-01 is the one most likely to have been skipped, because it is the focus area with no equivalent in the other frameworks and no primary ancestor, and SC5-DA2-01 assumes it directly. Check it before the unit rather than during. Our guide to Stage 4 Science and its 16 outcomes covers what should have been established, and using a student’s interests as the way into curriculum content covers keeping a Year 9 or 10 student engaged when the content turns evaluative.

What this sets up

Stage 5 ends compulsory Science in NSW, and Stage 6 splits into Biology, Chemistry, Physics, Earth and Environmental Science, Investigating Science and Science Extension. Because Science is not compulsory in Stage 6, Stage 5 performance is what a student and their school use to decide whether to continue at all.

• SC5-GEV-01 and SC5-GEV-02 (evolution and DNA) are the direct entry point to Stage 6 Biology, and SC5-DIS-01 leads into its infectious disease and immunity content.
• SC5-RXN-01 and SC5-RXN-02 (reaction types and rates) are the entry point to Stage 6 Chemistry, and the rate work in particular is what makes senior kinetics tractable.
• SC5-WAM-01 and SC5-WAM-02 (waves and Newton’s laws) lead into Stage 6 Physics, and SC5-WAM-02 is the outcome that most reveals readiness, since it is where the numerical work begins.
• SC5-ENV-01 and SC5-EGY-01 (human impact and energy evaluation) lead into Earth and Environmental Science, and they are the outcomes that make that subject legible as a science rather than as a policy discussion.
• SC5-DA2-01 and the analytical Working scientifically outcomes lead directly into Investigating Science, which is essentially those skills as a whole subject.
• SC5-WS-03 and SC5-WS-04 (valid, reliable and ethical design) become the depth study requirements that every Stage 6 science carries, and they are assessed directly rather than assumed.

Families comparing frameworks should note the grain and the scope differences together. The national curriculum publishes 19 content descriptions for Year 9 and 19 for Year 10, though 12 repeat word for word between them, and carries no disease content, see Year 9 Science under the Australian Curriculum and Year 10 Science under the Australian Curriculum. Victoria bands the two years into 29 descriptors and does carry disease, see Years 9 and 10 Science under the Victorian Curriculum. Our guide to which curriculum your state uses is worth a minute if you are unsure which applies.

A two-year teaching order

The Working scientifically outcomes are threaded through the content and NESA has told you which focus area develops which. What follows uses that mapping to sequence the eight focus areas across two years, so each skill outcome is introduced in a unit built to carry it.

1. Year 9, Semester 1: Reactions. SC5-RXN-01 reaction types, then SC5-RXN-02 reaction rates. Reactions carries four Working scientifically outcomes, all the practical ones, so this is the unit that establishes Stage 5 laboratory practice: SC5-WS-01 selecting instruments, SC5-WS-02 hypotheses, SC5-WS-03 designing valid, reliable and ethical investigations, and SC5-WS-04 following them. Rate experiments are ideal for it, since a rate investigation has an obvious independent variable and produces data worth arguing about.
2. Year 9, Semester 2: Materials, then Waves and motion. SC5-MAT-01 follows Reactions naturally, since assessing a material by its properties is chemistry applied, and it carries SC5-WS-03 again. Then SC5-WAM-01 waves and SC5-WAM-02 Newton’s laws, which carry SC5-WS-04 and SC5-WS-05, so this is where data processing and representation get their most demanding workout.
3. Year 10, Semester 1: Genetics and evolutionary change, then Disease. SC5-GEV-02 DNA and heritable characteristics before SC5-GEV-01 evolution, since natural selection acts on heritable variation and the mechanism should come first. Then SC5-DIS-01, which pairs naturally with genetics through inherited and infectious causes. Both carry SC5-WS-08 communicating arguments with evidence, so this semester is where written scientific argument should be assessed properly.
4. Year 10, Semester 2: Energy, Environmental sustainability, then Data science 2. SC5-EGY-01 evaluating energy use, then SC5-ENV-01 human impact, then SC5-DA2-01 to close. These three are the evaluative core of the stage and they build: energy choices produce environmental impacts, and both are argued about publicly using data whose legitimacy has to be assessed. Data science 2 belongs last because it is the general skill the two preceding units supply the material for. Finish with a full investigation carrying all eight Working scientifically outcomes.

Two orderings matter more than the rest. Reactions belongs first, because NESA attaches the four practical skill outcomes to it and everything later depends on those being established. SC5-GEV-02 belongs before SC5-GEV-01, because evolution without inheritance is a story rather than a mechanism, which is exactly what produces the need-based misconception.

Assessment checkpoints

• Genetics and evolutionary change: ask how a population of bacteria became resistant to an antibiotic. An answer starting from variation already present confirms SC5-GEV-01. “They got used to it” is the need-based version, so reinstate the four-part structure with variation first.
• Working scientifically: give a method that is highly repeatable and measures the wrong quantity, and ask whether it is a good investigation. Identifying the mismatch confirms SC5-WS-03. “Yes, the results were consistent” means validity and reliability have collapsed into each other, which is the central distinction of the stage.
• Working scientifically: ask what makes an investigation ethical, given that it is already safe. Any answer beyond safety, about consent, animal welfare or data collected from people, confirms the ethical clause in SC5-WS-03. “It is safe so it is ethical” means the two have merged, which they did not at Stage 4 because ethical was not yet required.
• Data science 2: give a real claim with a number attached and ask how they would check it. A sequence (what exactly is claimed, what data would settle it, where the data came from, whether it supports the claim or a narrower one) confirms SC5-DA2-01. “I would see if the source is reliable” alone means verification is being treated as source judgement rather than as method.
• Waves and motion: ask why a horse can accelerate a cart if the cart pulls back equally. Any answer separating the forces onto two different objects confirms SC5-WAM-02. “They cancel” means the third law was learned without the two-objects clause.
• Energy: ask them to compare two ways of generating electricity and say which is better. An answer naming the criteria before the verdict confirms SC5-EGY-01, since the outcome asks for evaluation on ethical and sustainability grounds and evaluation requires criteria. A verdict with no criteria is a preference, which is the standard gap in the evaluative outcomes.

Recording the alignment

Whether you are programming for a class or building evidence for a NESA home schooling registration, record the outcome on the activity as you go, and for Stage 5 Science record the focus area and the year alongside it. With only 19 outcomes across two years, almost every practical task touches several Working scientifically outcomes at once, and a portfolio that tags everything SC5-WS-04 proves far less than it appears to.

Keep the investigation design, not only the results. SC5-WS-03 is about designing a valid, reliable and ethical investigation, and none of those three can be evidenced from a completed results table. “SC5-WS-03, Year 9, designed the reaction rate investigation including which variable to control and why the ethical requirement went beyond safety, 12 May” evidences an outcome that a results sheet cannot. Our guide to state-by-state registration requirements covers what NSW reviewers ask for at the end of compulsory schooling, and how the NSW syllabuses are structured covers outcomes and content points if you are new to the format.

Sprout Lessons builds a full interactive lesson from any of these 19 outcomes, pitched at Stage 5 and built around whatever your student is into, with self-checking practice that hints rather than just marking wrong, and the exact NSW outcome recorded in the lesson footer. It earns its keep most on SC5-GEV-01 and SC5-DA2-01, where the misconceptions are strong enough to need many worked variations, and where in the case of data science no national-curriculum resource has a matching lesson at all.
