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.

Chemistry 11–12 · Chemistry · Atoms, bonding and the periodic table
Classifying substances as ionic, covalent molecular, covalent network or metallic by conductivity and melting behaviour
Whether a substance conducts as a solid, as a melt and in water, and how readily it melts, follows from the kind of particles and bonds it contains.
PracticalMedium riskFlame tests of metal ions and the line-spectrum model of energy levels
Each metal ion emits its own colour because electrons drop between discrete energy levels; the emitted wavelengths are fixed for that element.
Practical, model not builtMedium riskPredicting and building molecular shapes with Lewis diagrams, VSEPR and model kits
Electron domains around a central atom spread as far apart as possible, so counting bonding pairs and lone pairs predicts a molecule's shape, and the shape with the bond polarities decides whether the molecule is polar.
Practical, model not builtLow riskReactivity of Group 1 and Group 2 metals with water down and across the periodic table
Reactivity with water rises down Group 1 (lithium to sodium) and is lower for the Group 2 metals, following the trend in first ionisation energy.
Teacher-led practicalPracticalHigh riskSeparating a sand, salt and water mixture and finding its percentage composition
A heterogeneous mixture is separated by physical properties (particle size, solubility, boiling point) and the recovered masses give the percentage composition by mass.
PracticalLow riskSimple distillation of salt water: boiling-point plateau and purity of the distillate
A homogeneous mixture is separated by boiling point: the thermometer reads a plateau at the boiling point of the volatile component while the dissolved solid stays behind.
PracticalMedium riskBuilding and naming structural isomers with model kits: alkanes, alkenes, alcohols, esters
The same molecular formula can be assembled into different carbon skeletons or functional groups, and each arrangement is a distinct compound with its own IUPAC name and properties.
