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.

Environment and sustainability · Water
Evaporation race: sun, shade, wind and surface area
Evaporation is faster when water is warmer, when the air is drier or moving, and when more surface is exposed, and the rate can be measured as mass lost per hour.
Practical, model not builtLow riskWater cycle in a bag on a sunny window
Water evaporates when warmed, condenses on a cooler surface and falls back as drops, the same evaporation, condensation and precipitation that move water through the sky, land and ocean.
PracticalLow riskWhere does the water on a cold can come from? Finding the dew point
Air holds invisible water vapour, and when it touches a surface cold enough it condenses into drops, at a temperature called the dew point that a learner can measure with a can, ice and a thermometer.
Practical, model not builtLow riskAquifer in a tank: water table, wells and a leaking pollutant
Rain soaks into permeable layers and collects above impermeable ones; a well draws the water table down into a cone, and anything spilled at the surface follows the flow to the well.
PracticalLow riskPorosity and permeability of gravel, sand and clay
Porosity is how much water a sediment can hold and permeability is how fast it lets water through; both come from the size and packing of the grains, which is why an aquifer is sand or gravel and clay seals it.
Practical, model not builtLow riskWater cycle in a box: energy that lifts water and cold that returns it
Evaporation takes about 2.4 kJ from the water for every gram it lifts into the air and condensation gives it back, so the water cycle is also one of the main ways energy moves from the ocean to the atmosphere.
PracticalLow riskPorosity and permeability of sand, gravel and clay columns, with Darcy’s law
Pore space stores groundwater and connected pores let it flow, so the same measured columns show why an aquifer holds water and a clay layer confines it.
Practical, model not builtLow riskTreating turbid water: coagulation, settling and sand filtration measured by turbidity
Fine suspended particles that will not settle are clumped by a coagulant into flocs that do, and a sand bed traps what is left, the two steps at the heart of a water filtration plant.
PracticalLow riskWhere the Earth’s water is: a 1000 mL model of oceans, ice, groundwater and rivers
Only a fraction of a per cent of all water is fresh, liquid and at the surface, which is the quantity that people, plants and animals draw on.
