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.

A transversal on parallel lines: measuring the three angle relationships
When a transversal crosses parallel lines, corresponding angles are equal, alternate angles are equal and co-interior angles add to 180 degrees, and none of these hold when the lines are not parallel.
PracticalLow riskAngle sum of a triangle: torn corners on a straight line, checked with a protractor
The three interior angles of any triangle, placed together, make a straight angle, so they sum to 180 degrees whatever the triangle's shape.
PracticalLow riskInterlocking cube models: top, front and side views and isometric drawings
A solid built from cubes can be represented by its top, front and side views and by an isometric drawing, each of which shows some features and hides others, and outline views alone can fail to fix how many cubes a model contains.
Practical, model not builtLow riskCompass constructions: bisectors and an equilateral triangle, then measured
Constructions made with a compass and straight edge produce equal lengths and equal angles by design, and measuring the result with a ruler and protractor confirms the properties the construction guarantees.
PracticalLow riskWhich three measurements fix a triangle: congruence tests by construction
Triangles constructed from three sides, two sides and the included angle, two angles and a side, or a right angle with the hypotenuse and a side always match when overlaid, while three angles fix only the shape and two sides with a non-included angle can give two different triangles; the same tests explain why a diagonal splits a parallelogram into two congruent triangles.
Practical, model not builtLow riskNetworks from the school map: degrees, Euler trails and Euler's formula
A map of buildings and paths becomes a network of vertices and edges, and counting the vertices of odd degree decides whether every path can be walked exactly once, as Euler showed for the bridges of Königsberg.
Practical, model not builtLow riskThe angle in a semicircle: measured, traced with a paper corner and proved
Every angle subtended at the circumference by a diameter is a right angle, and conversely the corner of a right angle sliding against two fixed pins traces a semicircle on them as diameter, which a deductive proof with isosceles triangles explains.
