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.

Building an electromagnet: how turns of wire and current change its strength
An electric current in a coil produces a magnetic field, and the field grows with more turns of wire and with more current.
PracticalMedium riskHow magnetic pull falls off with distance: paperclips through card spacers
A magnetic force acts without contact and weakens quickly as the gap between magnet and object grows.
PracticalLow riskMapping the field around a bar magnet with iron filings and a plotting compass
A magnet exerts a non-contact force through the space around it, and the pattern of that field can be drawn as lines running from north pole to south pole that are closest where the field is strongest.
PracticalLow riskStatic electricity: charging balloons and rods by rubbing
Rubbing two insulating materials together transfers charge, and charged objects then exert non-contact forces of attraction or repulsion.
PracticalLow riskEnergy audit: power and energy use of household appliances on a plug-in meter
An appliance transforms electrical energy at a rate given by its power, so energy used equals power multiplied by time and can be measured, costed and compared with the rating label.
PracticalMedium riskGenerating electricity: a magnet moving through a coil and a hand-cranked generator
A generator produces electrical energy only while something keeps a magnet and a coil moving past each other, and the mechanical work done turning it is transformed into the electrical energy the circuit uses; power stations produce electricity the same way, with steam, wind or falling water doing the turning.
PracticalLow riskOhm's law: current against voltage for two fixed resistors
For a metal resistor at steady temperature the current is proportional to the voltage across it, and the constant ratio V / I is its resistance, so a larger resistance lets less current through at the same voltage.
Practical, model not builtLow riskResistance of a wire: how it changes with length
The resistance of a uniform wire is proportional to its length, because each extra centimetre adds the same opposition to the flow of charge.
Practical, model not builtLow riskSeries and parallel circuits: measuring current and voltage with one, two and three lamps
Adding lamps in series shares the supply voltage and lowers the current, while adding lamps in parallel gives each the full voltage and raises the total current drawn; the supply gives each unit of charge a fixed amount of energy, which series lamps share and each parallel branch receives in full.
