Specification Topics
Top Exam Tips
- Ensure you can apply mathematical skills such as ratios, surface area, and volume calculations to material quantities.
- Be prepared to link scientific knowledge, such as corrosion and oxidation, to material selection and surface treatments.
- Use specific examples of materials and technologies when answering extended response questions.
- Ensure you understand the difference between renewable and non-renewable energy sources and their respective arguments.
- Ensure you can classify materials into their main categories (e.g., ferrous vs non-ferrous metals, thermoforming vs thermosetting polymers).
- Practice calculating material requirements using standard stock forms and sizes.
- Be prepared to justify material choices using the factors: functionality, aesthetics, environmental, availability, cost, social, cultural, and ethical.
- Use correct technical terminology when describing manufacturing processes (e.g., wastage, addition, deforming, reforming).
- Relate scientific knowledge (e.g., corrosion, oxidation, alloy composition) directly to design applications.
- Ensure all design decisions are clearly recorded and justified in the portfolio.
Common Mistakes to Avoid
- Confusing physical properties with working properties of materials.
- Failing to link energy source selection to specific design contexts.
- Inaccurate use of technical terminology regarding mechanical systems.
- Lack of depth when discussing the impact of new technologies on society or the environment.
- Confusing physical properties (e.g., density, conductivity) with working properties (e.g., malleability, toughness).
- Failing to link material selection to specific commercial product requirements.
- Inaccurate calculation of material quantities due to ignoring stock forms or waste minimization.
- Superficial understanding of the 'six Rs' (reduce, refuse, re-use, repair, recycle, rethink) in a design context.
