describe that charge is a property of all matter and that there are positive and negative charges

the understanding that in most bodies there are an equal number of positive and negative charges resulting in the body having zero net charge

describe the production of static electricity, and sparking, by rubbing surfaces, and evidence that charged objects exert forces of attraction or repulsion on one another when not in contact

the understanding that static charge only builds up on insulators

explain how transfer of electrons between objects can explain the phenomena of static electricity

explain the concept of an electric field and how it helps to explain the phenomena of static electricity

how electric fields relate to the forces of attraction and repulsion

recall that current is a rate of flow of charge (electrons) and the conditions needed for charge to flow

conditions for charge to flow: source of potential difference and a closed circuit

recall that current has the same value at any point in a single closed loop

recall and use the relationship between quantity of charge, current and time
