Design and TechnologyQ&A by dot point
A short Q&A bank for every Wales Design and Technology syllabus dot point. Each question and answer is drawn directly from our worked dot-point page, so you can scan key concepts before opening the long-form answer.
Unit 1 Technical Principles
- Classification of papers and boards, timbers, metals, polymers and textiles into families, and the criteria used to select a material for a given product and context.4Q&A pairs
- The main categories of manufacturing process - wasting, shaping by casting and moulding, deforming and reforming, fabrication and joining - and how the chosen process depends on material, form and scale.4Q&A pairs
- The sources, origins and primary processing of materials (timber seasoning and conversion, metal extraction, polymerisation of crude oil, fibre sources) and the standard stock forms in which they are bought.6Q&A pairs
- The reasons for applying surface treatments and finishes (protection, durability, aesthetics, hygiene) and named finishes for timber, metal and polymer such as varnish, paint, galvanising, anodising, powder coating and self-finishing.3Q&A pairs
- The 6 Rs (rethink, refuse, reduce, reuse, repair, recycle) and the ecological and social footprint of products, including finite and non-finite resources and responsible material sourcing.3Q&A pairs
- Physical and mechanical working properties of materials - strength, hardness, toughness, ductility, malleability, elasticity, plasticity, density, durability, electrical and thermal conductivity - and how they govern selection and processing.2Q&A pairs
Unit 2 Design and Make Task
Unit 3 Technical Principles
- Composite materials (GRP, CFRP, concrete, plywood) that combine a matrix and reinforcement, and technical and performance textiles (Gore-Tex, Kevlar, microfibres, conductive textiles) engineered for specific functions.2Q&A pairs
- Scales of production (one-off, batch, mass and continuous), design for manufacture and assembly, tolerances, quality control and the use of jigs, templates and standard components.3Q&A pairs
- The influence of past and present designers, design companies and design movements (Bauhaus, Art Deco, Memphis, Modernism) on the styling, function and values of products.3Q&A pairs
- Design strategies (user-centred, iterative and collaborative design) and methods of communicating design ideas - freehand and formal drawing, modelling, CAD and CAM - and their roles in development.3Q&A pairs
- Electronic systems as input-process-output sub-systems, common sensors and components, and programmable components (microcontrollers) that make products smarter, more functional and reprogrammable.5Q&A pairs
- Life cycle assessment (raw materials, manufacture, distribution, use and disposal) and design strategies that lower impact across the life cycle, including design for disassembly, repair and recycling.2Q&A pairs
- Types of motion (linear, rotary, reciprocating, oscillating) and mechanical devices - levers, linkages, gears, pulleys, cams and followers, cranks - that change motion and provide mechanical advantage.3Q&A pairs
- Smart materials that respond to a change in their environment (shape memory alloys, thermochromic and photochromic pigments, quantum tunnelling composite, electroluminescent and piezoelectric materials) and modern materials developed through new processes.3Q&A pairs
- Types of force (tension, compression, shear, bending, torsion) and stress in structures, and techniques for reinforcing and strengthening structures (triangulation, webbing, beams, folding and laminating).2Q&A pairs
- The wider impact of design - social, moral and ethical issues, inclusive design, standards and legislation, the consequences of consumerism, and the role of enterprise and the designer's responsibilities.3Q&A pairs
