GRADE 9 Pre-technical – PROJECT Quiz
1. What is the first step when starting a simple woodworking project at school?
Planning and design come first so you know what to build, what materials and tools you'll need, and how long it will take. This reduces waste and mistakes.
2. Which unit should you use to measure timber lengths for a school project in Kenya?
Kenya uses the metric system, so measuring in centimetres and metres ensures accuracy and consistency.
3. What is the purpose of a bill of materials (BOM) for a project?
A BOM helps you buy the right amounts and estimate costs, preventing delays and extra trips to the shop.
4. Which personal protective equipment (PPE) is essential when using a bench grinder?
A bench grinder throws sparks and makes loud noise; goggles protect eyes and ear protection prevents hearing damage.
5. When cutting wood with a hand saw, which practice improves accuracy?
Clamping holds the work steady and a marked line guides the saw for a straight, accurate cut.
6. What is the safest way to carry a sharp tool like a chisel between benches?
Pointing the edge down and covering it reduces the risk of accidental cuts to you or others.
7. Which tool is best for checking that two edges are at right angles (90°)?
A try square is designed to check and mark right angles, making it ideal for joinery and layout work.
8. If your project requires joining two pieces of wood so they can be taken apart later, which fastener should you choose?
Screws and bolts can be removed and reassembled, whereas glue and nails are usually permanent.
9. What is the main reason for sanding wood after cutting and before finishing?
Sanding removes roughness and prepares the surface so paint, varnish or stain adheres evenly.
10. Which of the following is a good method to estimate the total cost of a small school project?
Listing materials and checking local prices gives a reliable estimate; adding contingency covers unexpected expenses.
11. In a team project, what is the best way to avoid confusion and wasted time?
Clear roles and communication ensure tasks are completed efficiently and responsibilities are understood.
12. Which material is most suitable for an outdoor bench that should resist rain in Kenya?
Treated timber or durable hardwood with a protective finish resists moisture and lasts longer outdoors.
13. What is the correct sequence of stages in a simple school project?
Projects work best when you design, plan materials and steps, carry out the making, then evaluate the result.
14. Why is it important to make a prototype or model before making the final product?
A prototype helps you try ideas, fix mistakes and improve the design without using expensive materials.
15. Which glue is commonly used for joining wood in classroom projects?
PVA glue is designed for wood; it bonds well and is safe and easy for school projects.
16. When using an electric drill, which action helps prevent the drill bit from slipping on the material?
A pilot hole or centre punch gives the bit a starting point and steady handling prevents slipping and wandering.
17. What is a sustainable choice when choosing materials for a school project?
Recycled or locally sourced materials reduce environmental impact, cost and support sustainability in projects.
18. Which hand tool is best for removing small amounts of metal to make a surface smooth?
A file is used to smooth or shape metal and wood by removing small amounts of material precisely.
19. Why should you clamp work firmly before drilling or cutting?
Clamping prevents the workpiece from moving, which reduces risk of injury and makes cuts or holes more precise.
20. What should you do with leftover paint or chemicals after finishing a project?
Proper storage or disposal prevents pollution and harm to people; schools usually have guidelines for safe handling.
21. When choosing nails or screws for a wooden joint that must be strong, which is usually better?
Screws give better withdrawal strength and can be tightened or removed, making them preferable for strong joints.
22. Which finishing material will protect wood from rain and show the wood grain?
Varnish seals and protects wood while allowing the natural grain to remain visible; stains add colour but varnish protects.
23. What is the purpose of a project evaluation sheet after completing a school project?
Evaluation helps learners reflect, learn from mistakes and improve future projects.
24. Which drawing best helps communicate the final shape and size of a project to classmates?
Scale drawings with labels show exact dimensions and shape, making it easy for others to understand the design.
25. During a group project, what is a fair way to decide who uses the limited power tools?
Scheduling and ensuring trained, supervised use keeps everyone safe and shares access fairly.
