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.

Physics · Materials, pressure and floating
Design and build a shelter that keeps a toy dry in wind and rain
Choosing materials by their tested properties and joining them in a stable shape produces a shelter that does its job.
PracticalLow riskFloat or sink: testing objects in water
Whether an object floats depends on what it is made of and, for a hollow shape, on the air that shape holds, not on how big the object is: objects of the same material behave the same way, and one piece of foil floats as a boat and sinks as a crumpled ball.
Practical, model not builtLow riskWhat is it made of: sorting objects by material and testing stiff or bendy
Objects are made from materials such as wood, metal, plastic, paper, fabric and rock, and each material has properties you can test.
PracticalLow riskWhich material keeps the water out
Some materials let water through and some do not, and that property decides what a raincoat, umbrella or roof is made of.
PracticalLow riskWhich strip is strongest: hanging washers until it bends
Materials differ in how much load they carry before they bend, and a count of washers makes that difference measurable.
PracticalLow riskFrom animal and plant to cloth: wool and cotton
Fibres for clothing come from living things: wool from sheep and cotton from a plant, and both can be turned into cloth by hand.
PracticalLow riskHow much can a strip hold? Testing paper, plastic, fabric and foil
Materials differ in strength and stretch, which can be measured by loading a strip until it breaks, and those properties decide what a material is used for.
PracticalLow riskWhich fabric soaks up the most water? Cotton, wool, polyester, nylon
Natural and made fibres have different properties, and absorbency, measured as water held per gram of dry fabric, is one reason a towel is cotton and a raincoat is nylon.
PracticalLow riskDensity of granite, basalt and pumice by water displacement
Rocks of the same size differ in mass because their minerals and pore spaces differ, and the density difference between continental and oceanic rock is what lets one plate sink beneath another.
Practical, model not builtLow riskThe Bernoulli effect measured in a Venturi tube
Where a flowing fluid speeds up through a narrow section its pressure falls, which a pair of water columns shows as a measurable height difference that Bernoulli’s equation predicts.
