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.

Clear all

A practical is carried out at the bench, in the classroom or outdoors. A practical with its model not built stands on its own; the page says where a step mentions the model. A calculation and data practical works from published figures by hand, with a calculator or in a spreadsheet. No Lab page includes an interactive model; the Concept Studio holds the demonstrations.

    Measuring cells with a calibrated eyepiece graticule

    A drawing or description of a cell stays qualitative until the microscope is calibrated; a graticule checked against a stage micrometer turns each observation into a measurement with a stated uncertainty.

    Mendel’s law of dominance: his counts, a bead model and a chi-square test

    Mendel’s law of dominance predicts a 3 : 1 ratio in the second generation; his own counts and a bead model test whether departures from 3 : 1 are within chance.

    Slaters in a damp and dry choice chamber, with a chi-square test

    Counting where animals settle turns a behaviour into quantitative data, and a statistical test shows whether a small sample is enough to support the pattern the eye sees.

    Priestley’s restored air made measurable: algae and hydrogencarbonate indicator

    Priestley inferred that plants restore air that burning or breathing had spoiled; hydrogencarbonate indicator lets a learner measure the same effect as carbon dioxide removed in light and added in darkness.
