PSc.3.3.1
• Identify interactions between charged objects - opposite charges attract and like charges repel.
• Compare the three methods of charging objects: conduction, friction, and induction – explain the re-distribution or transfer of electrons
for each method for both positively and negatively charged objects.
• Compare static and current electricity related to conservation of charge and movement of charge (without calculations).

• Interpret simple circuit diagrams using symbols.
• Explain open and closed circuits.
• Apply Ohm’s law and the power equation to simple DC circuits: V IR = and P VI = .
• Compare series and parallel circuits. Conceptually explore the flow of electricity in series and parallel circuits. (Calculations may be
used to develop conceptual understanding or as enrichment.)

PSc.3.3.3
• Explain how the wire in a circuit can affect the current present – for a set voltage, the current in a wire is inversely proportional to its
resistance (more current exists where resistance is low); the resistance of a material is an intensive property called resistivity; increasing
the length of a wire increases the resistance; increasing the temperature increases the resistance; increasing the diameter of a wire
decreases its resistance.
• Explain using a cause-and-effect model how changes in composition, length, temperature, and diameter of a wire would affect the
current in a circuit.
