Study Hub
Study Guides
This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
This unit develops pupils' knowledge of mechanisms through levers and linkages. They will apply this knowledge by exploring mechanisms and incorporating them into an interactive book with a user-centred focus.
Lesson Summary
You will learn to identify different linkages within existing products.
Key Notes
- Interactive books have a variety of linkages inside them.
- Linkages are chosen to carry out a purpose in a product.
- Analysis of existing book designs can help develop new designs.
Vocabulary To Learn
- product: an item designed to be used
- purpose: an intended function or result
- input: the motion used to start a mechanism
- output: the motion created by the input
Common Mistakes To Avoid
- All linkages can be found in interactive books.
3 Quick Questions (With Answers)
1. Explain the lesson in two key points.
Interactive books have a variety of linkages inside them. Linkages are chosen to carry out a purpose in a product.
2. What does this key word mean in this lesson? 'product'
an item designed to be used.
3. Correct this common mistake.
Mistake: All linkages can be found in interactive books. Correction: Not all linkages are suitable for use in an interactive book. Those that are used are chosen because they are the simplest, most functional option for the intended purpose.
