    • A CHAIR could be made of wood because• The wood has a good appearance• It is strong, tough• It can be environmentally friendly (it depends on the type of wood)• It is not usually expensive (it depends on the type of wood) But if we want an outdoor CHAIR, maybe it is better to make it of plastic: • The plastic has a better resistance to humidity, so it will last longer • It has some flexibility, so the chair can be more confortable • It is cheaper than wood • It is not as heavy as wood
    • A PAN is made of metal because:• It is a good conductor of heat, so when it is on the fire it can transmit heat to the meat we put on it.• But at the same time, it has a good resistance to heat, so it does not melt when it is on the fire• We choose metals that are resistant to oxides and corrosion• We can make the handle of plastic, because it is a good insulator of heat and it has a good textureA Book is made of paper (and cardboard) because:• It is flexible, so we can fold the pages if necessary• It is not too heavy, so we can carry it wherever we want• It is biodegradable and we can recycle it• It has a good texture, so it is nice to touch• It can be easily printed and we can write on it if necessary
    • A WIRE is made of metal (usually copper), because:• It is a good conductor of electricity• It is ductile, so we can make easily wires from this kind of material• It is flexible, so we can bend it to make an electric circuitAnd they are usually covered by plastic, because:• It is a good insulator of electricity, so we can avoid short circuits when two wires are together and shocks when we touch them A JACKET could be made of fabric because: • It is a good insulator of heat, so we are warmer when we wear it • It is flexible, so we can easily take it on and off • It is not too heavy, so we can carry it on without effort • It has a good texture, so it is nice to touch
