Ability to explain the mechanical or structural choices made during the project. 4. Key Scientific & Engineering Concepts to Assess
The memorandum will look for explicit use of triangles. Triangles do not deform easily under loads, making them the foundational shape for trusses.
Measurable criteria the solution must meet (e.g., "Must span 400 mm," "Must support a load of 2 kg").
Consideration of safety for users and minimal impact on the river ecosystem. (4 marks) Part 2: Design (20 Marks) Focuses on technical drawing and planning skills. technology grade 9 mini pat term 1 memorandum
if the learner provides at least two distinct, free-hand ideas showing different structural shapes or triangulation methods.
Identify two forces acting on a bridge.
Produce accurate 3D orthographic and oblique drawings of the solution. Ability to explain the mechanical or structural choices
Don’t copy a memo online without understanding it. Your teacher will ask you why you used a triangle shape or why you made the base wide. If you understand the memo’s logic (struts resist compression, ties resist tension), you will pass easily.
At least two or three rough, freehand sketches of different ideas.

In the South African National Curriculum Statement (NCS) and Curriculum and Assessment Policy Statement (CAPS), the Mini-Practical Assessment Task (Mini-PAT) is a core component of the Technology subject. In Grade 9, Term 1, the Mini-PAT bridges the gap between theoretical knowledge and practical engineering.
List of features the solution must have (e.g., maximum height, materials allowed).
