Lab
See the idea. Put it to the test.
956 practicals from Kindergarten to Year 12, in 9 subjects. A practical gives the idea, what you need, the steps, what you should see and a safety card. A teacher-led practical gives the idea and its hazards; its method is for tutors on the learning platform.
Review
Reviewed before publication (owner’s confirmation, 24 September 2026). That covers every practical here, and a practical’s page lists the sources its author read.
A safety card on every page
The risk, who supervises and the hazards. The 38 teacher-led practicals show their idea and hazards here; their materials, steps and sources, and any result, control or note that states a number or an amount, are for tutors and administrators on the learning platform.
School laboratory, not for home
207 practicals are medium or high risk. Each says so on its page: In a school laboratory, with a teacher supervising, under the school's risk assessment. Not for home.
Curriculum references
Each practical lists the NSW syllabus outcomes and Australian Curriculum v9 codes it supports. They are references, not a verified or complete curriculum alignment.

Mathematics · Percentages
A half, a quarter, a fifth and a tenth of real quantities
A unit fraction of a quantity is found by dividing the quantity into that many equal parts, so 1/4 of 2 L is 500 mL and 1/5 of 1 m is 20 cm, and measuring one part checks the division.
PracticalLow riskPercentages on a metre rule and a jug
A percentage is a number of hundredths of a whole, so on a metre rule 40 percent is 40 cm and on a 250 mL jug it is 100 mL.
Practical, model not builtLow riskScale drawing of the classroom at 1:50
A ratio of 1:50 turns every measured length in the room into a drawn length one fiftieth as long, and every drawn length back into a real one by multiplying by 50.
PracticalLow riskA dripping tap: measuring a rate and scaling it to litres per day and per year
A rate compares two quantities with different units, so a volume collected in a measured time gives millilitres per minute, which is the gradient of a straight volume-time graph and scales by unit conversion to litres per day and per year.
Practical, model not builtLow riskIncome tax and the Medicare levy with the 2026-27 resident tax rates
Australian income tax is progressive: each rate applies only to the part of taxable income inside its bracket, so the average rate always sits below the top marginal rate.
Calculation and dataLow riskWhat an appliance costs to run: measured energy in kilowatt-hours and the household bill
Power is a rate of energy use, so kilowatts multiplied by hours gives kilowatt-hours, and a measured kilowatt-hour figure multiplied by the tariff on a bill gives a running cost.
Practical, model not builtMedium riskA reducing balance home loan and a credit card balance at current RBA rates
Each month a loan balance grows by interest and falls by the repayment, so a spreadsheet of the reducing balance shows why early repayments are mostly interest and why extra repayments save so much.
Calculation and dataLow riskHow fast does a car lose value: declining balance depreciation from advertised prices
A car loses a roughly constant fraction of its value each year, so real advertised prices by age follow a declining-balance curve rather than a straight line.
Practical, model not builtLow riskSimple and compound interest at a real savings rate from the Reserve Bank
Compound interest adds interest to the balance each period, so the balance grows geometrically, and compounding more often at the same annual rate adds slightly more each time.
Calculation and dataLow riskSuperannuation as an annuity: 12 per cent super guarantee over a working life
Equal contributions that each earn compound interest add to a geometric series, so the future value of an annuity has a closed form and grows much faster than the sum of the contributions.
