Learn what are conductors and insulators with these interactive learning resources for KS2 Science students aged 7-11 from BBC Bitesize.

Conductors have a band gap close to 0 eV (electronvolts), semiconductors range approximately between 1 and 9 eV, and anything above is usually considered an insulator.

Researchers have discovered a material that can switch between an insulator and a conductor freely, even at room temperature. The material, a compound of manganese and sulfide (MnS2), starts off ...

Atomically thin sheets of graphite are metal-like conductors — until they react with hydrogen, when they become insulators. This curious effect could be an excellent model for studying metal ...
