  2. Plastics are made by the chemical industry. Are they natural or synthetic? Synthetic

  3. What are most plastics made from? Oil

  4. Give two examples of a plastic. Polythene, polystyrene, perspex, PVC, nylon, Kevlar, bakelite, formica and silicones

  5. Give an advantage of a plastic over a natural material? Plastics do not rot like iron. They are lighter then most metals.

  6. What does it mean if a material is biodegradable? Broken down by bacteria and rot away

  7. Most plastics are non biodegradable.What does this tell us about a plastic? They do not rot/ they are not broken down by bacteria

  8. Why is it dangerous to burn a plastic? Poisonous gases are given off. Carbon monoxide is given off.

  9. Name the 3 ways of disposing of plastics ? Burying, burning & recycling.

  10. What is a thermoplastic? A plastic which melts and can be reshaped on heating.

  11. Name the process of joining up monomers to make a polymer. Polymerisation

  12. Name the polymer made by joining ethene molecules together. Polyethene

  13. What size is a molecule if it is a polymer? A large molecule

  14. Name the polymer made by joining styrene molecules together. Polystyrene

  15. Why is important to recycle plastics? They are made from oil which is a finite resource. Oil will run out.

  16. Name the monomer which is used to make the polymer polypropene. Propene

  17. What name is given to the small molecules used to make a polymer? Monomer

  18. Name a toxic gas given off when a plastic is burned. Carbon monoxide
