Contents
Outcomes
- Movement of electrons causes insulators to gain electrostatic charge
- Electrostatic charges can apply forces on one another
Specification References
- 2.19 identify common materials which are electrical conductors or insulators including metals and plastics
- 2.20 recall that insulating materials can be charged by friction
- 2.21 explain that psoitive and negative elecrostatic charges are produced on materials by the loss or gain of electrons
- 2.22 recall that there are forces of attraction between unlike charges and forces of repulsion between like charges
Starter
- Structure of an atom recap – get pupils to label each part of the atom
Main Body of Lesson
- Rod rubbing – Water stream, bits of paper, other rods on watch glass
- Balloon rubbing
- Only electrons move, only insulators store charge
