Technology Grade 9 Mini Pat Term 1 Memorandum -

A typical memo allocates 70 marks in total, divided into sections. Here is a standard breakdown:

| Section | Activity | Marks | |---------|----------|-------| | 1 | Investigate (problem statement, research, specifications, constraints) | 10 | | 2 | Design (initial sketches, final design, justification) | 15 | | 3 | Make (planning, use of tools, safety, quality of construction) | 20 | | 4 | Evaluate (testing against specifications, improvements) | 10 | | 5 | Communication (drawings: 3D, 2D with dimensions, labels) | 15 | | Total | | 70 |

Note: Some schools may use 60 or 80 marks – the percentages remain consistent. technology grade 9 mini pat term 1 memorandum

| Criteria | Marks | |----------|-------| | Problem statement clearly described | 2 | | Who the solution is for (user/context) | 2 | | What the solution must do | 2 |

Example acceptable answer:

“I am going to design and make a model of a crane that can lift a load of 200 g from the floor to a height of 300 mm. The crane must be stable and operated by a simple crank mechanism.”

  • 5.2 Suggest one improvement to your design. (1)
  • 5.3 Explain how a real Jaws of Life tool helps in a car accident. (2)

    • The memo typically gives:

  • 2.2 What type of movement does the arm of a rescue spreader make? (1)
  • 2.3 Draw a simple, labelled sketch of a single-acting hydraulic cylinder. (4)
  • 2.4 Why is a pivot (fulcrum) important in the scissor-like arms? (3)

    • | Criteria | Marks | Explanation | |----------|-------|-------------| | Identifies at least two real-life examples of the device | 4 | e.g., Tower crane, suspension bridge, hydraulic lift | | Describes how each example works (simple mechanism or structural principle) | 4 | e.g., “Uses a counterweight to balance the load” |

    | Criteria | Excellent (Full Marks) | Acceptable (Half Marks) | Not Acceptable (0 marks) | |----------|------------------------|--------------------------|---------------------------| | Sketch 1 | Isometric, labeled, proportional | 2D, unclear labels | No sketch | | Final model | Neat, strong, spans gap | Wobbly but complete | Broken or missing | | Testing | Measured load, recorded | "It worked" only | No testing | | Drawing | 3 views, mm dimensions | 1 view, no units | No drawing | A typical memo allocates 70 marks in total,

  • 3.2 List TWO specifications (3)
  • 3.3 List ONE constraint. (1)
