6.1

Properties of Materials

Materials have different properties like hardness, flexibility, and the ability to conduct heat or electricity, which determine what they're used for.

1

Why is rubber used to make tyres instead of glass?

Rubber is flexible and can absorb shocks, while glass is brittle and would shatter

2

Why is copper used for electrical wires?

Copper is a good conductor of electricity, allowing current to flow through it easily

6.2

Natural and Man-made Materials

Natural materials come directly from nature (like wood and cotton), while man-made materials are created through human processes (like plastic and nylon).

1

Is cotton a natural or man-made material?

Natural, since it comes from the cotton plant

2

Is plastic a natural or man-made material?

Man-made, since it's manufactured from chemical processes
