Study Guides
This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
Pupils will handle, shape and join sheet materials using different manufacturing processes. They will test and experiment with different mechanical fixing methods and adhesives and then use this knowledge to explain which choices are suitable and why.
Lesson Summary
You will learn to use materials efficiently.
Key Notes
- Minimising waste is important for both economic and environmental reasons.
- Stencils and templates are used to ensure materials are used efficiently.
- Nesting is used to ensure materials are used efficiently.
Vocabulary To Learn
- accurate: correct and precise, with no mistakes
- efficient: using materials in a way that minimises waste
- tesselation: arranging identical shapes in a repetitive pattern without gaps or overlaps
- nesting: arranging varying shapes onto material to make the best use of space
Common Mistakes To Avoid
- Minimising waste means reducing the size of a product.
3 Quick Questions (With Answers)
1. Explain the lesson in two key points.
Minimising waste is important for both economic and environmental reasons. Stencils and templates are used to ensure materials are used efficiently.
2. What does this key word mean in this lesson? 'accurate'
correct and precise, with no mistakes.
3. Correct this common mistake.
Mistake: Minimising waste means reducing the size of a product. Correction: Using materials efficiently can be achieved by reducing size, but also by working accurately. This can be done by using stencils / templates, tesselation and nesting.
