Supporting Powerpoint for OCR A. Includes notes on: dynamic vs static electricity movement of electrons and ions. conductors and insulators Conventional current vs electron flow Showing a plasma ball is optional and not on the specification but its weird and cool and the students like it. This also applies to the Van Der Graaf Generator if you have one.
