Lesson 6Fun with polymers

Starter

• The properties of Ms G are:– Female– Teacher– Loud mouth– Dark hair– Pregnant!

• So what does ‘properties’ mean?

When you think of things made of plastic, what do you think

of?

Did you get any of these?

What properties do they have?

Weird polymers

• There’s also plastics with very weird properties.

• We’re going to do some experiments with them today

• Put all your thoughts and ideas on your sheet

Experiments we will do

• How much water will a nappy hold?• How does the nappy polymer

work?• Making bouncy balls from PVA glue

Nappies!

• Watch Ms G demo opening a nappy

• The powder inside is a type of polymer

• Now you do your experiments…• …and don’t forget to fill in the

sheet!

Make your own clothes!

• We are going to make our own disposable clothes

• The polymer we are using completely disappears in hot water!

• What things would this polymer be useful for? Why is it SO fab?

Homework

• This lesson we’ve looked at some amazing polymers that scientists have designed

• Invent a polymer and a use for it• Be as imaginative as you can!
