Make sure you complete the questions.

What can we do to help?

• How can we reduce the amount of rubbish thrown away?

• Prizes for the most imaginative!

• You could even have them filmed…

What is a plastic?

• Another name for plastic is polymer.• If we could zoom in on a polymer we

would see that it’s made of a long chain of different particles called monomers.

• Watch the video discuss:– What did the girls use as a ‘monomer’?– What did they do to the monomers to make a

‘polymer’? What did they say it’s called?– Do you think it’s easy to reverse the reaction?

Making polymers

• Watch Ms G do the demo.

• How do we explain what is happening in the experiment?

• When the two ingredients are added in the correct order, they react to form a polymer

Making models of polymers

• To make a model of the nylon polymer from the demo, one person should add paperclips of alternating colour, whilst the other person extends the chain away from the mixture.

• What do the different colour paperclips represent?

Time to be famous…

• Make a 2-3 minute film teaching someone what a polymer is.

• Use the paper clips as props

• Use the whiteboards and pens for captions

• Speak clearly!
