Question 21 of 25intermediate🔍 AnalyzeShort Answer3 marks

List five objects and pair them with a material that is not suitable for it! Explain why these materials will not work to make these objects.

Correct Answer

Five odd pairs of objects with unsuitable materials are:

1) A chair made of paper - paper is too weak and would tear under weight.

2) A water bottle made of cloth - cloth would absorb water and leak.

3) A window made of cloth - cloth is opaque and would not allow us to see outside.

4) A shoe made of glass - glass is brittle and would break while walking.

5) A book made of metal - metal is too heavy and rigid for turning pages.

Each material has specific properties that make it suitable or unsuitable for particular uses.

Explanation

The 'Odd Pairs' activity on Page 10 encourages students to think about why certain materials are unsuitable for specific objects. The chapter gives an example: 'Walls - can't be made of water' because walls need to be solid and stable. This activity develops understanding of material properties and their appropriate applications.

Solution Steps

  1. A chair made of paper is unsuitable because paper is too weak and would tear under weight

  2. A water bottle made of cloth is unsuitable because cloth would absorb water and leak

  3. A window made of cloth is unsuitable because cloth is opaque and blocks visibility

  4. A shoe made of glass is unsuitable because glass is brittle and would break while walking

  5. A book made of metal is unsuitable because metal is too heavy and rigid for turning pages

  6. Materials have specific properties that determine their suitability for different uses
