## Learning Outcomes for Electric Circuits

The list below displays sample learning objectives for the unit on Static Electricity. The various activities from the Lesson Plans have been organized by objective. This format of organizing The Physics Classroom's activities may be more useful to some teachers than the Lesson Plan format. It is worth noting that the activities identified below only include those activities included on the Lesson Plans and in the Pre-Built Task Tracker courses. Additional activities are referenced on the Teacher Notes page.

### 1. Electric Potential and Electric Potential Difference

Relate electric potential to the energy per charge and the electric potential difference between two locations to the change in energy per charge moved between the two locations; identify the units of electric potential and distinguish between high and low potential locations.

### 2. A Model of Charge Flow in a Circuit

Identify the two requirements of an electric circuit; describe charge as marching together through the circuit loop at the same rate at every location, never accumulating nor being used up; describe the conducting components (wires, bulbs, batteries, etc.) of the circuit as being the source of charge and describe the battery as being the energy source that is used to pump the charge uphill from low energy to high energy to establish an electric potential difference across the two ends of the external circuit..
