Technology Grade 9 Mini Pat Term 1 Memorandum

The Grade 9 Technology Term 1 Mini-PAT typically focuses on designing and constructing a bridge to solve community-based accessibility problems caused by flooding. Assessment involves an investigation, technical drawings, and building a model, with a focus on structural stability and cost-effectiveness. For full documentation and examples, see Twinkl and Studocu. Grade 9 Technology Mini-PAT: Bridge Construction Project

Question 3: List specifications and constraints (6 marks)

| Specifications (4 marks) | Constraints (2 marks) | |--------------------------|------------------------| | Must lift 200 g | Only recycled materials allowed | | Height: 300 mm | Time limit: 3 hours | | Base size: max 200×200 mm | Cost: no new materials | | Manual crank mechanism | |

3. The Making Process (15–20 marks)

The memo checks:

• Following the plan: Did you stick to your sketch?
• Quality of work: Are the joints neat? Is the structure square?
• Use of tools: Did you use glue, scissors, or a saw appropriately?

Common memo note: "Learner loses 2 marks if they changed the design without explaining why." technology grade 9 mini pat term 1 memorandum

Story: "The Community Solar Bench"

A small coastal town struggled with frequent power outages during storm season. Mara, a Grade 9 learner in the town, loved tinkering with electronics and wanted to help. For her Mini PAT project she designed a "Community Solar Bench" — a sturdy wooden bench with an integrated small solar panel, a battery, two USB charging ports, and a low-power LED light strip.

Mara began by surveying local needs: residents wanted a safe place to recharge phones and a well-lit seating area near the community centre. She sketched a design, listing materials (wood planks, weatherproof solar panel, 12V lead-acid battery, charge controller, voltage regulator for 5V USB output, LED strip, wiring, switches, waterproof enclosure, screws, and sealant). She used basic electrical concepts to calculate expected output: with a 20W panel and average 5 hours of peak sun, the bench could generate ~100 Wh per day — enough for several phone charges and a few hours of LED lighting.

She created a circuit diagram showing the solar panel connected to a charge controller, the controller to the battery, and from the battery to a voltage regulator supplying the USB ports and the LED(s). Mara built a prototype frame, assembled components, sealed connections, added safety features (fuses, covered terminals, weatherproof box), and labeled the USB ports. She tested the bench on a sunny weekend, measured voltage and current with a multimeter, recorded energy production and usage over three days, and adjusted the angle of the panel for better output. Question 3: List specifications and constraints (6 marks)

Mara presented her bench to the community: explaining the design, demonstrating how to use it, showing test data, and discussing limitations (reduced output in cloudy weather, battery lifespan, and maintenance). The community agreed to adopt two benches and asked the local school to maintain them. Mara wrote a short maintenance guide and a simple budget estimate for replacement parts.

Total Marks: 70

Marking Summary:

• Investigation: ___ / 20
• Design: ___ / 20
• Making (practical): ___ / 25
• Evaluation: ___ / 5
• Grand Total: ___ / 70

Teacher Notes for Using This Memorandum:

1. Adjust marks if your school uses a different total (e.g., 50 or 100).
2. The "Making" section must be assessed while learners work and after completion.
3. Allow sketches in pencil – clarity and labels are more important than artistic skill.
4. For the hydraulic system, 10ml and 20ml syringes with plastic tubing work best.
5. If your topic is different (e.g., "bridge" or "crane"), replace Section A and B questions accordingly, but keep the same structure.

2. The Design Sketches (20–25 marks)

This is the biggest section. The memo uses a scale:

• 0 marks: No sketch.
• 1–2 marks: A rough drawing, no labels.
• 3–4 marks: A 2D drawing with dimensions.
• 5 marks: A detailed 3D isometric sketch, labels showing tension (pulling) and compression (pushing), and a list of materials.

Pro tip: If the memo says "labels", you must write "strut" (handles compression) or "tie" (handles tension) on your drawing.
