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.

    Testing rocks: scratch, streak, fizz and soak

    Rocks and minerals have observable, testable properties, hardness, streak colour, reaction with acid and water absorption, that tell us what they are made of and what they are useful for.

  2. Science and Technology K–6 · Year 5

    Acid rain on limestone: chalk dissolving in vinegar

    Chemical weathering dissolves some rocks, and calcium carbonate in chalk or limestone reacting with a weak acid loses mass that a balance can track, with the fizz as carbon dioxide.

    Freeze-thaw weathering: ice cracks a plaster rock

    Water in a crack expands by about 9 percent when it freezes and can split rock, a slow change that a plaster brick with a water-filled cavity reproduces in a freezer overnight.

    Rock tumbling with sugar cubes: physical weathering by the shake

    Rocks knocked together in a river or by waves lose their corners and shed grains, and shaking sugar cubes in a jar measures that wear as mass lost against number of knocks.

    Stream table: watching water carve a landscape

    Moving water erodes, transports and deposits sediment, and a tray of sand on a slope shows the channel, the load and the fan forming, with slope and flow as the variables that change them.

    Shake table: which structure survives an earthquake?

    Sudden shaking of the ground in an earthquake pushes structures from side to side, and a frame braced with triangles on a wide base resists the shaking far better than an unbraced rectangular frame, which is why buildings in earthquake zones are braced.
