While specific scenarios vary by school and textbook, a typical Term 1 Mini-PAT memorandum follows this marking weight distribution: Assessment Component Expected Output Design Brief, Specs & Constraints Design (Sketches) Freehand conceptual ideas Design (Final) 3D Oblique/Isometric & Orthographic Manufacturing Finished model, stability, neatness Evaluation Self-assessment checklist & report Total Available 60 Marks 4. Key Conceptual Answers Required in Grade 9 Term 1

This comprehensive memorandum serves as a marking guideline and instructional framework for the Grade 9 Technology Mini-Practical Assessment Task (Mini-PAT) for Term 1. It aligns with national curriculum standards focusing on mechanical systems, structural design, and graphic communication. 1. Introduction to the Mini-PAT

to solve community accessibility issues. The total assessment is usually out of and covers the complete technological design process. Core Assessment Structure technology grade 9 mini pat term 1 memorandum

No. Exam memos focus on written answers. The Mini PAT memo is a performance rubric .

Marks are often lost simply because drawings are messy or pages are missing.

Identification of the Problem: Students must clearly describe the scenario provided in the PAT.The Design Brief: A short statement starting with "I am going to design and make..." that outlines the general solution.Specifications: A list of specific requirements the product must meet (e.g., dimensions, materials, safety features).Constraints: A list of things that limit the project (e.g., budget, time, available tools). Phase 2: Design and Development | Specifications (4 marks) | Constraints (2 marks)

Explain why triangulation is used in truss bridges. (2)

This memorandum is designed to ensure consistency in grading and to provide a clear roadmap for completing the Grade 9 Technology Mini PAT. By following the design process and meeting the specifications outlined in the brief, students can successfully demonstrate their technical knowledge and practical skills.

By trading distance for force. For example, using a smaller driver gear to turn a larger follower gear increases the turning force (torque) but reduces the speed. Forces Acting on Structures Students are often asked to identify forces on their model: Core Assessment Structure No

Once the model is complete, it must be tested against the original specifications.

I am going to design and draw a mechanical mine hoist system to safely lift heavy miners and rock loads from a deep underground shaft to the surface. Marking Guideline: Specifications and Constraints

Note: The specific scenario for the Grade 9 Term 1 Mini PAT varies by country and school system (e.g., South African CAPS curriculum often uses "Rescue or Safety Device" or "Jaw of Life" model). This memorandum is based on the If your scenario differs, adapt the content criteria accordingly.

Identification of different bridge types (Suspension, Arch, Truss) and their suitability for the given scenario. (5 marks)
