What the syllabus expects you to be able to do.

4.2.1.1State that there are positive and negative charges.
4.2.1.2State that like charges repel and unlike charges attract.
4.2.1.3Describe simple experiments to produce charges by friction and to detect them.
4.2.1.4Explain that charging by friction moves only negative charge (electrons).
4.2.1.5Describe an experiment to tell electrical conductors from insulators.
4.2.1.6Use a simple electron model to explain the difference between conductors and insulators, with examples.
4.2.1.7Supplement: state that charge is measured in coulombs.
4.2.1.8Supplement: describe an electric field as a region where a charge feels a force.
4.2.1.9Supplement: state that the field direction is the direction of the force on a positive charge.
4.2.1.10Supplement: describe the field patterns around a point charge, around a charged sphere and between two oppositely charged parallel plates.
