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.

The school grounds as a network: minimum spanning tree and shortest path from measured paths
Buildings joined by measured paths form a weighted network, in which a minimum spanning tree connects every building with the least total length and a shortest path may use edges the tree does not include.
Practical, model not builtLow riskHow many people can leave per minute: network flow through measured doorways
The largest flow through a network of doorways and corridors is limited by its narrowest cut, so widening the wrong doorway changes nothing.
Practical, model not builtLow riskSetting up the hall: critical path analysis from timed activities
When activities depend on one another, the longest chain of dependent activities fixes the shortest possible completion time, and activities off that chain have float.
