What is Plastic?
Plastic is used in insulation, window frames, etc. in our homes and new cars are full of plastic fittings, plastic electrical parts and plastic cables. But what is plastic? Well, plastic is the name of some man-made polymers produced by a chemical process. A polymer is formed by joining together many molecules of a substance into a long chain. These polymer chains can consist of many thousands of molecules. You can imagine one looking like a long strand of cooked spaghetti. In a plastic material there will be thousands of these strands. Plastic means flexible and easily moulded, just like a heap of spaghetti where all the strands can slide over and around each other.
Types of Plastic
Plastics are divided into 7 main types and are marked by a symbol with a number inside it. like those below. If you examine a plastic object you should find one of these symbols stamped on it.
Uses of Plastics
PET water and juice drink bottles, trays for vegetables
PE-HD bottles for washing-up liquids, bottle caps
PVC window frames, pipes, electrical insulation
PE-LD plastic bags, plastic wrap
PP ice cream boxes, flower pots, rope
PS disposable cups, yogurt and sour cream cartons, CD covers
OTHER e.g. melamine, a more rigid plastic, which is often used for plates and cups

Project: A Day without Plastic
- Organise the class into groups of 3-5.
- Make a list of all the disposable plastic items used in the space of one day (24 hours), e.g. yoghurt cartons, plastic cups, containers for take-out food, water bottles, plastic bags or wrap for your lunch, chocolate wrapping, etc. The items may be ones which are reused several times, but they will eventually be disposed of, such as water bottles for example. Groups compare your lists.
- For the next 24 hours, try and do without as many of these items as possible. Use a glass for your water instead of a plastic bottle. Again each group writes down all the disposable plastic items used in the test period.
- See which group manages to use the smallest number of plastic items per person in the space of 24 hours. Which group had the biggest reduction in the number of plastic items used? Work out the percentage reduction.
