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.

Class shop: paying and giving change with Australian coins
A coin stands for a value rather than a count of one, so the same amount can be made with different coins, and change is found by counting on from the price to the amount paid.
Practical, model not builtLow riskDollars and cents: making $1 many ways and weighing coins
One dollar is 100 cents, so an amount is written in dollars and cents and made from many coin combinations, and because 5c, 10c and 20c coins have a mass in proportion to their value, a dollar of any of them has the same mass.
Practical, model not builtLow riskTenths and hundredths: a flat as one whole
When a flat is one whole, a rod is one tenth and a unit cube is one hundredth, so decimals name parts of a whole in the same base-10 pattern as whole numbers.
Practical, model not builtLow riskEstimate the docket, then check it: rounding to judge whether a total is reasonable
Rounding every price before adding gives a total close enough to judge whether the printed total is reasonable, and the rounding rule chosen decides whether the line-by-line errors cancel or pile up.
Practical, model not builtLow riskOne sheet of paper: dividing measurements by 10, 100 and 500
A quantity too small to measure directly is found by measuring many copies and dividing, and dividing by 10 or 100 moves every digit one or two places to the right, while dividing by 500 is that two-place shift followed by a division by 5.
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 riskPlanning a class event to a set budget from advertised prices, then checking the spend
A plan is built by turning a number of people into a number of packs, packs into a cost and a cost into a decision against a fixed budget, and the model is only finished when the real docket is set beside the plan and the difference is accounted for.
Practical, model not builtLow riskThousandths: decimals on a metre and a zooming number line
A millimetre is one thousandth of a metre, so decimals with three places are lengths on a metre rule and are ordered by looking at each place in turn.
