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.

Geography · Water in the world
Rain on bare soil and covered soil: measuring runoff and washed-away sediment
Plant cover and mulch slow rain, so less water runs off and far less soil is carried away, which is why erosion control on farms and building sites starts with keeping the ground covered.
PracticalLow riskErosion trays: bare soil, mulched soil and turf under the same rain
Plant cover and mulch slow water and hold soil, so the same rainfall carries far less soil off a covered slope than off a bare one.
PracticalLow riskWhere is Earth's water: dividing one litre by the real proportions
Almost all of Earth's water is sea water and most fresh water is ice or underground, so the water people draw from rivers and lakes is a tiny share.
Practical, model not builtLow riskCatchment model: where the rain goes
Rain that falls anywhere inside a catchment boundary drains to the same low point, carrying whatever is on the surface with it.
PracticalLow riskAquifer in a tank: porosity, permeability and a pumped well
Groundwater fills the pore space between grains; how much a layer holds is its porosity and how fast water moves through it is its permeability, and pumping a well lowers the water table around it.
Practical, model not builtLow riskCreek discharge from a cross-section and float timing
Discharge is cross-sectional area multiplied by velocity, so a creek's flow in litres per second can be measured with a tape, a ruler and a floating orange.
Practical, model not builtMedium riskHow much rain does the roof catch: from gauge depth to tank litres
Rainfall depth times catchment area gives a volume, so a school roof and a rain gauge reading predict the litres a tank receives from one storm.
Practical, model not builtLow riskRing infiltrometer: how fast water soaks into three surfaces
Infiltration rate falls as the soil wets up and differs by surface, which decides how much rain becomes runoff instead of soil water.
Practical, model not builtLow riskStorm hydrograph from a stream table: bare catchment versus sponge wetland
A catchment turns a short burst of rain into a longer, lower outflow, and storage on the surface (vegetation, wetlands) lengthens the delay and lowers the peak, which is what reduces flooding downstream.
Practical, model not builtLow riskWaterwatch water quality testing of a local waterway
The health of a waterway is measured by a fixed set of physical and chemical readings plus the animals living in it, compared against published guideline ranges.
