See, the light comes on. Not so good. And that's because this plastic and rubber band are insulators; they don't allow the electricity to flow easily through them. So, over here I have a metal wire.

The researchers showed that the atomic structure in the thin-film Mott insulator Ca 2 RuO 4 —part ... "This is a great example of complexity arising from simplicity," said Oleg Gorobtsov ...

Pupils can discuss how they can find out more about conductors and insulators through planning a science investigation themselves. After watching the film, you could work with pupils to ...
