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.

Earth and space · Earth's history and deep time
Geological time walk: 4,600 million years on a 46 metre tape
Rock-cycle processes take millions of years; laying Earth's history along a tape at one centimetre per million years puts all of human existence in the last few millimetres.
Practical, model not builtLow riskSediment settling in a jar: sorting, layers and Stokes' law
Grains settle at speeds set by their size, so one stirred mixture lays down a graded bed with the coarsest grains at the base, the pattern that lets a geologist read which way up a rock was deposited.
Practical, model not builtLow riskA scale model of geological time from the International Chronostratigraphic Chart
Almost all of Earth history passed before complex life; a scaled timeline built from the chart’s numerical ages makes the proportions of the eons and the brevity of human time visible.
PracticalLow riskMaking mould, cast and trace fossils in clay and plaster
A fossil is usually not the organism but the shape it left, a mould, the filling of that shape, a cast, or the mark of its activity, a trace.
PracticalLow riskSediment layers in a jar: superposition, grading and reading a sequence
Sediment settles with the oldest layer at the base, coarsest grains first in each pulse, which is the rule that lets a rock sequence be read in order.
PracticalLow riskStrike, dip and the order of events at an outcrop or road cutting (fieldwork)
Beds are laid down close to horizontal, so a steep measured dip records tilting or folding that came after deposition; with superposition, cross-cutting relationships and unconformities, strike and dip readings put the events at an outcrop in order.
PracticalMedium riskLogging the strata in a rock cutting
A rock face gives qualitative observations (colour, structures) and quantitative ones (bed thickness, grain size, dip), and the principle of superposition turns the measured log into an inferred sequence of events.
