Divide the resource kit into Thermo plastics and thermo set plastics.

I am going to ask your group what property does the plastic have to put it into one of the two groups.

There are key property words to help you.

Demo

Heat strip and HIPS

Normally I would let you make a product like a mobile phone stand so that you can explore the properties for yourself.

AFL

Working in small groups fill in worksheets and keep in your folders for future revision.

Plenary

Turn to your classmate and ask a question that checks your classmates understanding of properties. It could be whacky!

What wouldn't you make a book out of and why?
