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.

Fizz in a sealed bottle: a new substance, and no mass lost
Bicarbonate of soda and vinegar react to make new substances, including carbon dioxide gas, an irreversible change; in a sealed bottle the total mass stays the same, and it falls only when the gas is let out.
Practical, model not builtMedium riskLemon cells: chemical energy into electrical energy
Two different metals in an acidic fruit make a cell that transforms chemical energy into electrical energy; one cell gives less than 1 V and a tiny current, so cells are joined in series to light an LED.
PracticalLow riskRusting steel wool: what it needs and how much air it uses
Rusting is an irreversible change in which iron combines with oxygen and water to form a new substance, so steel wool rusts only when both are present, rusts faster with salt, and uses up the oxygen in the air around it.
