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.

How much wheat can the rain grow: the French and Schultz potential yield model
In a dryland wheat biome the growing-season rainfall sets a ceiling on grain yield, because a fixed amount of water is lost from the soil surface before the crop can turn water into grain.
Calculation and dataLow riskSalinity and crops: a seedling trial checked against FAO salt-tolerance data
Salt in soil water reduces plant growth once it passes a threshold that differs by crop, which is why land clearing that raises saline groundwater cuts food production.
Practical, model not builtLow riskSoil texture by sedimentation: a jar test timed by Stokes' law
A soil's sand, silt and clay fractions settle out of water at very different speeds because settling speed rises with the square of grain size, and the fractions decide how a soil holds water and supports a biome's productivity.
