This assessment focuses on and Mechanical Systems , specifically evaluating learners' ability to apply the Design Process (Investigate, Design, Make, Evaluate, and Communicate) to solve a real-world problem. Typically, the scenario involves designing and building a model of a bridge, a crane, or an overhead gantry crane using truss structures and mechanical advantages like pulleys or gears.
The memo often awards partial marks if the learner can explain why it failed and suggest improvements – this shows evaluation skill.
The your class is using (e.g., mine hoist, bridge, cell phone tower) technology grade 9 mini pat term 1 memorandum
Identifying why the structure or mechanism is needed.
Your design needs to be turned into a real product, which requires accurate technical drawings. . This assessment focuses on and Mechanical Systems ,
Justification for choosing specific materials based on properties like strength, flexibility, or cost.
Initial Sketches: At least two or three rough ideas showing different perspectives.Evaluation of Ideas: A brief explanation of why the final idea was chosen over the others.Formal Drawings: 3D oblique or isometric drawings, as well as 2D orthographic projections (front, top, and side views).Labeling and Dimensions: All drawings must include accurate measurements and labels for parts and materials. Phase 3: Making the Product (Realization) The your class is using (e
Here are key insights from the memorandum to help you earn top marks:
A Grade 9 Mini-PAT is structured around the universal design process. The memorandum allocates marks across these distinct phases: Phase 1: Investigate
This phase evaluates the fabrication of the physical model bridge or tower based on safe workshop practices and material processing. 3.1 Resource and Tool Management (5 Marks)
