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.

Matchstick growing patterns: from a table of values to a linear rule
A growing row of squares adds the same number of sticks each time, so the count follows a rule of the form M = 3n + 1 that can be read from the structure, tabulated and plotted as points on a straight line that does not pass through the origin.
Practical, model not builtLow riskRates from timed walking: a distance-time graph from real data
Speed is a rate, distance per unit time, and it appears as the gradient of a distance-time graph drawn from stopwatch readings taken at measured marks.
Practical, model not builtLow riskGradient of a real ramp: rise over run with a spirit level, checked by angle
The gradient of a straight ramp is its vertical rise divided by its horizontal run, the same at every point along it, and it can be written as a ratio 1 : n, as a percentage and as an angle whose tangent is the gradient.
PracticalLow riskStacking cups: a linear relationship with a measured gradient and intercept
The height of a stack of identical cups grows by the same amount for every cup added, so height against number of cups is a straight line whose gradient is the lip height and whose intercept is the cup body below the lip.
Practical, model not builtLow riskCatch-up walkers: when and where two measured walks draw level
Two steady walks are two linear equations in time and distance, and the time and place at which the walkers draw level is their simultaneous solution, found algebraically or as the intersection of their graphs and then tested on the track.
