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.

Science and Technology K–6 · Physics · Energy and heat
Does a ball bounce back as high as it was dropped
A dropped ball never bounces back to the height it fell from, and a higher drop gives a higher bounce.
PracticalLow riskBlack can, white can: which warms faster in the sun?
The Sun is a source of heat energy, and a dark surface absorbs more of it than a light one, so water in a black can warms faster than water in a white can.
Practical, model not builtLow riskMelting race: which surface melts an ice cube fastest?
Ice melts when heat energy flows into it, and the surface it sits on controls how fast that heat arrives, so a metal tray melts a cube far faster than a foam plate.
PracticalLow riskMixing hot and cold water: where the heat goes
When hot and cold water mix, heat energy moves from the hotter to the colder until both share one temperature, and that temperature can be predicted from the masses and starting temperatures.
Practical, model not builtLow riskWhere does heat come from? Measuring five heat sources
Heat energy comes from several sources, the Sun, friction, electricity, chemical reactions and our own bodies, and each can be measured as a temperature rise.
PracticalLow riskWhich spoon warms first? Heat conduction in metal, wood and plastic
Heat energy is conducted along a solid, and metals conduct far better than wood or plastic, which is why a metal spoon in hot water soon feels warm at the handle.
PracticalLow riskKeep it cold: which wrapping slows an ice cube's melting?
An insulating material slows the flow of heat, so ice wrapped in wool or bubble wrap melts more slowly than ice in foil or bare, which is why eskies and jumpers work.
Practical, model not builtLow riskStretch and roll: how a stronger push sends a car farther
A stronger applied force, here a rubber band stretched further, transfers more energy to a toy car, so it rolls farther before friction stops it; for a band that stretches evenly, doubling the stretch roughly quadruples the distance.
Practical, model not builtLow riskSolar cell angle test: light energy into electrical energy
A solar cell transforms light energy into electrical energy, and the current it delivers depends on how directly the sunlight strikes it, which is why rooftop panels are tilted toward the Sun.
