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.

Galileo's ramp: a rolling ball's distance grows with the square of the time
A ball rolling from rest down a straight incline covers a distance proportional to the square of the elapsed time, so the distance-time graph is half a parabola, distance against time squared is a straight line, and the distances in successive equal intervals go 1 : 3 : 5 : 7.
Practical, model not builtLow riskBouncing ball: rebound heights as an exponential decay
Each bounce returns a fixed fraction of the height it fell from, so successive rebound heights form a geometric sequence and the graph of height against bounce number is an exponential decay rather than a straight line.
Practical, model not builtLow riskCompound interest as exponential growth, checked against Moneysmart
An amount that grows by a fixed percentage each period follows A = P(1 + r/n)^(nt), an exponential relationship whose graph curves upward, and the compounding frequency changes the outcome by a computable amount.
Calculation and dataLow riskLogarithmic scales: what one unit of earthquake magnitude means
On a logarithmic scale each step multiplies rather than adds, so one unit of earthquake magnitude is ten times the shaking amplitude and about 32 times the energy, and two magnitudes from a real catalogue can be compared as a ratio.
