2.20 identify common materials which are electrical conductors or insulators, including metals and plastics



**2.21 recall that insulating materials can be charged by friction**


 * 2.22 explain that positive and negative electrostatic charges are produced on materials **
 * by the loss and gain of electrons **

** 2.23 recall that there are forces of attraction between unlike charges and forces of repulsion between like charges **



**2.24 explain electrostatic phenomena in terms of the movement of electrons** Image: [|PHET balloon simulation]

**2.25 recall the potential dangers of electrostatic charges, eg when fuelling aircraft and tankers**
