Plastic is made in factories from oil.
It can be hard or soft.
It is strong.
It lasts for a long time.
It is used to make bottles, toys, clothing and furniture.
What is plastic?
Plastic is made in factories using chemicals found in oil and natural gas. It can be coloured by adding dyes. Hot plastic can be poured into moulds in the shapes of toys and other things. It can also be squeezed through holes to make pipes and hoses and bags.
It can be hard and used to make things such as casings for television sets, garden pots, and even furniture.
It is strong but it isn't heavy. It is very light. Because it is so light, many parts of aeroplanes and cars are made from plastic. This means it takes less energy to move these machines and so they use less energy (fuel).
It can be soft and used to make things such as soft toys, balls umbrellas, and paddling pools.
It can be made into thin threads and then woven to make material that is used to make clothing such as rain coats and waterproof jackets. These plastic materials are called synthetic (say: sin-thet-ick) materials.
Do you know about these different kinds of plastic?
Nylon was invented in 1935 by a scientist working for an American Company called Du Pont. The company wanted an alternative to natural silk. Nylon was used to make toothbrushes, womens' stockings and parachutes. Now it is used to make carpets.
Styrofoam is a plastic full of air bubbles. It was invented in 1941. Because it is light weight and can float it was first used in the construction of lifeboats. Sheets of styrofoam can be used to insulate buildings, for packaging goods. It is used to make plates and disposable cups. (probably not good for the environment!)
Kevlar was developed in 1965. Kevlar is a lightweight but amazingly strong (stronger than steel!) plastic. It is used to make body armour for police and soldiers, spacesuits and even bridges. It is used in racing cars and in aeroplanes too.
Plastic and the environment
Old plastic can be recycled. Once it is cleaned it can be used to make new bottles and bags. It doesn't rot and can't be burned safely. (Burning plastic gives off dangerous gases) So it is hard to get rid of it. Plastic rubbish takes up a lot of space in garbage dumps. To help our environment we need to use it carefully and save and reuse it whenever we can.
Reuse and recycle
Limit your use of plastic: carry a non plastic reusable water bottle, bring your own bags to the supermarket rather than use their plastic carry bags.
Reuse plastic bags, carry lunch in a reusable lunch box, and put plastic objects into a recycle bin so it can be melted and made into new things.
Plastic rubbish causes so many problems on land and in our oceans and rivers. By putting plastic into recycle bins we can help the planet.
