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.

    Metal or non-metal: testing lustre, conductivity and malleability

    Elements can be sorted as metals or non-metals by testing physical properties, and a few elements such as graphite and silicon break the pattern, which is why the classification rests on several properties rather than one.

    Splitting water: two volumes of hydrogen to one of oxygen

    Water is a compound of two elements in a fixed ratio; an electric current decomposes it and the 2 : 1 gas volumes match the formula H2O.

    Rutherford's gold-foil experiment as a rolling-ball model of the nucleus

    Most of an atom is empty space with a tiny, dense, positively charged nucleus, because most alpha particles pass straight through a foil and a very few bounce back.

    Flame tests: identifying metals by the colour of their light

    Each element gives out light of its own colours when its electrons drop back to lower energy levels, so a flame colour identifies the metal in a compound.

    Lithium and sodium in water: reactivity down group 1

    Elements in the same group react in the same way and their reactivity changes in a regular order down the group, which the periodic table was built to show.

    Salt, sugar and wax: properties that reveal ionic and covalent substances

    Ionic substances such as sodium chloride have high melting points and conduct only when their ions are free to move, while covalent molecular substances such as sugar and wax melt easily and never conduct.
