Unit 6 - Electricity and Magnetism (2016)


*Magnet Lessons

4C’s: On a daily basis, students will use various methods of communication, think critically to solve problems or draw conclusions, Utilize their creativity to find different solutions, illustrate their work, ask their own questions, and work smarter, Collaborate to accomplish the above

Learning Objectives:


• 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.)

• Explain how the flow of electricity through series and parallel circuits is affected by voltage and resistance.



• 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.


• Describe the characteristics and behaviors of magnetic domains.

• Explain the attractions of unlike poles and the repulsion of like poles in terms of magnetic fields.

• Explain magnetic fields produced around a current-carrying wire and wire coil (solenoid).

• Explain the relationship between strength of an electromagnet and the variance of number of coils, voltage, and core material.


• Explain the relationship between electricity and magnetism in practical applications such as generators and motors – the process of electromagnetic induction in electric generators that converts mechanical energy to electrical energy; transformation of electric energy to mechanical energy in motors.

• Extrapolate other practical applications such as security cards (ATM, credit or access cards), speakers, automatic sprinklers, traffic signal triggers, seismometers, battery chargers, transformers, AC-DC adapters.
