Question 1: Describe a technique you could use to join two pieces of wood permanently. Explain how this technique works.

Answer: A common technique is gluing and clamping. The glue creates a strong bond between the surfaces, and clamps hold the pieces tightly until the glue sets, resulting in a secure joint.

Question 2: Explain the process of using a soldering iron to join two electrical wires together. Include safety precautions.

Answer: The process involves heating the soldering iron, applying it to the wire joint, and adding solder to create an electrical connection. Safety precautions include wearing safety glasses, working in a well-ventilated area, and handling the hot iron carefully to avoid burns.

Question 3: Sketch a simple plan of a product that uses a removable lid. Label the main parts of your design.

Answer: A clear sketch should show a container with a lid that fits snugly on top. Labels should include: container body, lid, sealing rim, and any handles or locking mechanisms.

Question 4: Describe a technique used to shape metal parts in product making. Include a brief explanation of the steps involved.

Answer: One technique is pressing or stamping. It involves placing a metal sheet into a die and applying pressure with a press to form the desired shape. This process is often used for producing consistent, repeated shapes efficiently.

Question 5: Draw a cross-section of a plastic bottle showing the main features needed for it to hold liquids safely. Include the neck, body, and base in your sketch.

Answer: A correct sketch would include a cylindrical body, a narrower neck with threading for a cap, and a flat or slightly rounded base. The walls should be uniform, and the neck should be designed for a screw-on cap.

Question 6: Identify and explain a technique used to smooth rough edges on a wooden product.

Answer: Sanding is commonly used. It involves rubbing the rough edges with fine-grit sandpaper to produce a smooth surface, reducing splinters and improving the product's finish.

Question 7: Design a simple plan for a key holder that can be mounted on a wall. Include dimensions and materials you would use.

Answer: A suitable plan would include a rectangular wooden or plastic base measuring approximately 15cm x 5cm, with holes for screws at each end. Include hooks or pegs for keys, spaced evenly. Materials could be wood or sturdy plastic.

Question 8: Explain how a crimping tool is used to join metal wires or connectors. What are the benefits of using this technique?

Answer: A crimping tool compresses a connector onto a wire to create a secure electrical connection. Benefits include a quick, reliable, and strong joint that doesn't require soldering, ideal for electrical work.

Question 9: Sketch a design for a biodegradable packaging container that can be easily folded. Label the fold lines and main features.

Answer: A correct sketch would show a flat sheet with fold lines indicating where to fold to form a container with a base, sides, and a lid. Features include fold tabs and locking mechanisms if necessary.

Question 10: Describe the process of embossing on a metal sheet and give an example of a product that uses this technique.

Answer: Embossing involves pressing a design into the metal sheet using a die and a press, creating a raised pattern. An example is decorative metal panels or jewelry components.

Question 11: Identify two safety precautions you should take when using a hot glue gun.

Answer: Safety precautions include wearing protective gloves to avoid burns and working in a well-ventilated area to avoid inhaling fumes. Also, always unplug the glue gun when not in use.
