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.

Control groups and blinding: a double-blind taste test with a binomial test
Blinding, random order and a probability calculation separate a real ability to tell two products apart from chance and from expectation.
Practical, model not builtLow riskReaction time from a falling ruler: reliability, sample size and outliers
One measurement of reaction time is unreliable; repeated trials and larger samples shrink the uncertainty of the mean, and each outlier has to be judged against a stated rule rather than deleted.
Practical, model not builtLow riskSample size and sample selection: drawing beads from a bag
Small samples scatter widely around the true proportion and the spread shrinks with the square root of sample size, while a biased way of choosing the sample misleads at every size.
