2.4 Different materials for the same object
The use of the object determines the type of material it should be made of.
Imagine a bicycle with wooden wheels.
Do you think the wheels will turn and work as well as steel and rubber? Materials are chosen and used for the properties they have.
ACTIVITY:
Identifying different materials I
NSTRUCTIONS:
1. Look at the pictures of different chairs below . Even chairs can be made from many different materials (plastic, wood, metal, canvas, etc) or a mixture of more than one material.
2. Identify the types of materials that each chair is made from.
3. Write down where that material comes from
"identify"は日本の学校ではどのように習うのでしょうか。重要単語・基礎単語ですね。
実験後には次の文章が書かれています。
Similar objects such as balls used in sport, can be made from very different materials, depending on what the object is used for.

2.3 Properties of materials
Raw and manufactured materials have specific properties. We already looked at some of the properties of raw and manufactured materials by describing them. The properties of a material help determine how it is used. For example, plastic is waterproof so some rain jackets are made of plastic to keep the rain off and keep you dry. A rain jacket made from wool or fibre would not be waterproof and you would be soaked! This is because the wool is an absorbent material (it absorbs water).
Hard or soft?
A material is described as hard when you cannot scratch it, you cannot cut it and you cannot dent it. Hardness measures how diffcult or easy it is to change the shape of the material, either by denting, cutting or scratching it. A diamond is an example of a hard material as diamond cannot be scratched by other objects. In fact, diamond is so hard it is used on drill bits to drill through rocks and many other materials The opposite of hard is soft! Think of the wet, raw clay from the previous chapter. This clay is soft and can therefore be moulded into a new shape.
このようなテキストに中高生で触れることができれば、理工学部に進学する生徒さんは楽になりますね。
hard、softに対して toughnessの説明(p.163) は次のようになっています。
If you hit a metal coin with a hammer, there will be no or little damage. If you hit a piece of chalk with a hammer it will break into pieces. The metal coin is tough compared to the chalk. The chalk is very fragile.Toughness measures how much energy is needed to break a material.
信頼という精神的抽象的なものが国家の資源になっている
ってすごいですよね？こんな国が現実にあるということが素晴らしい。
技術開発などは人々の幸福を目指して行われているわけですが、
信頼という"invisible"な価値も常にその幸福の基礎にあることを忘れてはいけませんね。
「信頼」は英語で…と考えて頭に浮かぶ単語は何ですか？？？
特許などでは性能などに関して信頼性が高いということをreliable/reliablyと表現します。

Trust: A cornerstone of Danish culture
もうこのサイトの内容が感動ものです
少し引用しますので、英語の勉強を兼ねて読んでみてね
デンマークの豊かさは、まだ会ったことのない人を信じるという社会的信頼から生まれているようです
In each other we trust
Trust comes in different forms. Most people trust their friends and family, but Denmark also benefits from what anthropologists call a general societal trust, which is the ability to trust people you have never met before. In Denmark, people are assumed to be honest and reliable unless they somehow show that they are not.
Trust, an invisible Danish resource
Trust is an invisible resource in the Danish society. It means fewer social conflicts and crime because it creates a sense of harmony that increases happiness and security.
