Explain why safety is important when using workshop tools.

Safety is important to prevent injury, ensure correct use of tools, and maintain a controlled working environment, reducing risks such as cuts or accidents.

Give two safety precautions when using a tenon saw and explain why.

Use a bench hook to secure wood to prevent slipping, and keep fingers away from the cutting line to reduce risk of injury.

Explain why controlled movements are important when using a saw.

Controlled movements improve accuracy and reduce the chance of slipping, lowering injury risk.

Describe the function of a tenon saw.

A tenon saw is used for making straight, accurate cuts in wood due to its rigid back.

Explain the risks of using a coping saw.

The blade may snap or slip, causing injury if not used carefully.

Give two safety precautions when using a coping saw.

Keep the blade tight and cut slowly while securing the material to maintain control.

Explain why a coping saw is used for curves.

Its thin blade allows it to turn easily, making it suitable for curved and intricate cuts.

Explain what a chisel is used for.

A chisel is used to remove wood or shape joints accurately.

Explain a key safety rule when using a chisel.

Always cut away from the body to prevent serious injury if the tool slips.

Explain why hands must be kept behind the blade when chiselling.

This reduces the risk of the blade cutting into the hand if it slips.

Explain the function of a pillar drill.

A pillar drill is used to drill precise vertical holes in materials.

Explain the main risk of a pillar drill.

The material can spin or clothing can get caught, causing injury.

Explain how to use a pillar drill safely.

Clamp material securely, wear goggles, and tie back hair to prevent accidents.

Explain why clamping material is essential when drilling.

It prevents the material from spinning, improving accuracy and reducing injury risk.

Explain what softwood is.

Softwood is timber from coniferous trees that is generally less dense and easier to work with.

Explain why softwood is used in school projects.

It is easy to cut and shape, lightweight, cheap, and suitable for beginners.

Explain why softwood is easier to shape than hardwood.

It has a lower density and softer fibres, requiring less force to cut.

Explain why cost matters when choosing materials.

Cheaper materials reduce overall project cost and make them accessible for school use.

Explain why timber must be sanded before finishing.

Sanding removes imperfections and creates a smooth surface for better finish adhesion.

Explain what happens if wood is not sanded properly.

The surface remains rough and finishes may not stick evenly.

Explain the sanding process.

Sanding involves using progressively finer grits to smooth the surface.

Explain the purpose of coarse grit sandpaper.

It removes large imperfections and rough surfaces quickly.

Explain the purpose of fine grit sandpaper.

It produces a smooth finish ready for painting or varnishing.

Explain why sanding must follow the grain.

Sanding with the grain prevents scratches and produces a smoother finish.

Explain what the grain of wood is.

The grain refers to the direction of the wood fibres.

Explain what a finish is in DT.

A finish is applied to protect wood and improve appearance.

Explain why finishes are applied.

To protect wood from damage and enhance its appearance.

Explain vacuum forming.

A process where heated plastic is shaped over a mould using a vacuum.

Describe the steps of vacuum forming.

Heat plastic, place over mould, apply vacuum, allow to cool and harden.

Explain why plastic must be heated in vacuum forming.

Heating softens the plastic so it can be shaped easily.

Explain the role of the vacuum in vacuum forming.

The vacuum removes air, forcing plastic tightly over the mould.

Explain advantages of vacuum forming.

It is quick, accurate, and suitable for mass production.

Explain what a design brief is.

A design brief is a statement describing what needs to be designed and who it is for.

Explain what a specification is.

A specification is a detailed list of requirements the product must meet.

Explain why specifications are important.

They allow products to be tested to ensure they meet requirements.

Explain how a specification improves design quality.

It ensures all user needs and constraints are considered.

Explain what function means in design.

Function refers to how well a product performs its intended purpose.

Explain what aesthetics means.

Aesthetics refers to how a product looks and appeals visually.

Explain what ergonomics means.

Ergonomics refers to designing products for comfort and ease of use.

Explain why ergonomics is important.

It improves user comfort and reduces strain or injury.

Explain what sustainability means in DT.

Sustainability involves using materials and processes that do not harm the environment.

Explain why sustainability matters.

It reduces environmental impact and preserves resources.

Explain what durability means.

Durability refers to how long a product lasts without damage.

Explain why durability is important.

A durable product lasts longer and reduces waste.

Explain what accuracy means in manufacturing.

Accuracy ensures parts fit correctly and function properly.

Explain why accuracy is important.

Poor accuracy can lead to faulty or unsafe products.

Explain what quality control is.

Quality control ensures products meet required standards.

Explain why quality control is important.

It ensures safety and consistency in products.

Explain what a prototype is.

A prototype is an early model used to test a design.

Explain why prototypes are useful.

They allow testing and improvements before final production.

Explain what evaluation means in DT.

Evaluation involves judging how well a product meets its specification.

Explain why evaluation is important.

It identifies strengths and areas for improvement.
