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 · Multiplication
Fair shares: dealing a collection into equal groups
Sharing one at a time gives every group the same number, and sometimes some are left over.
PracticalLow riskCube towers: skip counting by twos, fives and tens
Equal towers turn counting by ones into counting by twos, fives or tens, and a staircase of towers that grow by the same step is an additive pattern whose missing terms can be predicted.
Practical, model not builtLow riskEqual groups and arrays with counters
Equal groups arranged in rows make an array, and turning the array shows that 3 rows of 4 and 4 rows of 3 hold the same number.
Practical, model not builtLow riskArrays and area: multiplication facts to 10 by 10
A multiplication fact is the number of squares in a rectangle of rows and columns, so a hard fact can be split into two easy rectangles and added.
Practical, model not builtLow riskTimes tables on a circle: an algorithm that draws patterns
Following a fixed sequence of steps (multiply, keep the last digit, join that point on a ten-point circle) turns each times table into a shape, and the shape depends on the factors the multiplier shares with 10.
Practical, model not builtLow riskRectangles from counters: factors, primes and square numbers
The rectangles that can be made from a number of counters show its factors, a prime makes only a single row, and a square number makes a square.
Practical, model not builtLow riskRemainders in context: 50 shared into groups of 6
The same division, 50 ÷ 6, has different answers in different situations: round up when everyone needs a place, drop the remainder when only full groups count, and split it into a fraction or decimal when the quantity can be cut.
PracticalLow riskSieve of Eratosthenes: an algorithm that finds the primes to 100
Crossing out the multiples of each prime in turn removes every composite number, and once the multiples of 2, 3, 5 and 7 are gone every number left up to 100 is prime, because 11 × 11 is already more than 100.
Practical, model not builtLow riskSquare numbers and square roots with tiles
A number is a perfect square when its tiles form a square array, its square root is the side of that array, and a number with tiles left over has a square root between two whole numbers.
