- Electric Charge and Static Electricity  Charges that are the same repel each other. Charges that are different attract each other.

- Electric Charge and Static Electricity  An electric field is a region around a charged object where the object’s electric force is exerted on other charged objects.

- Electric Current  Electric current is the continuous flow of electric charges through a material.

- Electric Current  An electric circuit is a complete, unbroken path through which electric charges can flow.  (Read information on a basic circuit, but do not worry about the associated Activity 1).

- Electric Circuits Simple symbols are used to diagram a circuit.

- Electric Current  Use the website below to explore the difference between conductors and insulators (at the atomic level).   Be sure to click on the ‘Explore Some More’ button to see an example of a lab that tests for conductors and insulators (YOU will be writing a lab just like this one!!)

- Electric Current  Two factors that affect the resistance of water flowing in a pipe are diameter and length. The diameter and length of a wire also affect resistance in a circuit.
