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.

Measuring with a microscope: field of view, magnification and a scale bar
The width of the field of view is a known length at each objective, so the size of a cell can be estimated by counting how many fit across it.
Practical, model not builtLow riskPlant and animal cells: onion epidermis and cheek cells side by side
Plant cells have a wall and a regular shape while animal cells do not, and both have a nucleus and membrane visible after staining.
PracticalMedium riskPlasmolysis in red onion cells: the membrane pulls away from the wall and returns
The cell membrane controls what passes into and out of a plant cell while the cell wall keeps its shape: in a strong salt solution water passes out of the cell, so the membrane and the purple vacuole shrink away from the wall, and in pure water they swell back.
PracticalLow riskPotato cylinders in sugar solutions: mass change across a concentration series
Plant cells take in water through the cell membrane from a dilute solution and lose it to a concentrated one, so potato cylinders gain mass in water and lose it in strong sugar solution, and one concentration in between gives no change.
