The bridge must be able to withstand heavy rains and the weight of multiple people. It must be durable and require minimal maintenance.
This Mini-PAT is designed to assess the learners' capability to apply the Design Process (Investigate, Design, Make, Evaluate, Communicate) to a real-world structural challenge. Assessment Breakdown (15 Marks) Design Process Phase 2: Design (15 Marks) Design Process Phase 3: Make (20 Marks) Design Process Phase 4: Evaluate (10 Marks) Design Process Phase 5: Communicate (10 Marks) Total Marks: 70 Marks Part 2: Phase-by-Phase Marking Memorandum Phase 1: Investigate [15 Marks]
The memorandum is divided into four main sections, mirroring the design process. Phase 1: Investigation (Approx. 20–25 Marks)
Identification of Pratt, Howe, or Warren trusses. (2 Marks)

The Term 1 project is almost always based on a problem scenario. While the specific village and river name may change from year to year (e.g., Muledane/Mvudi River, KwaNogawu/uThukela River), the core problem remains the same. Learners are presented with a community that is cut off from essential services by a river that becomes dangerous to cross during the rainy season.
The walkway could use timber planks, and the support structure might use steel I-beams for strength.
A crushing or pushing force (e.g., the vertical legs of a tower structure). 5. Tips for Teachers Grading the Mini-PAT
Structure collapsed immediately; no scientific evaluation provided. technology grade 9 mini pat term 1 memorandum
Realized model matches dimensions specified in Phase 2 drawings within a tolerance.
If a student devises an unconventional way to reinforce a joint that works perfectly, award full marks for manufacturing innovation.
Are there specific involved, such as pulleys, levers, or gears? Share public link
The assessment criteria for the Technology Grade 9 Mini PAT Term 1 Memorandum typically include: The bridge must be able to withstand heavy
Identifying appropriate types of bridges (truss, suspension, beam) and materials (wood, metal, concrete).
Selection of appropriate materials (e.g., lollipop sticks, corrugated card, wire) that mimic real-world properties. ( 2 Marks )
Structure supports load with less than 5 mm center deflection.
Develop technical drawing skills, including first-angle orthographic projection and isometric views. Assessment Breakdown (15 Marks) Design Process Phase 2:
