In electricity, students will define current and explain the parts of a circuit as well as the movement of electrical charges. In addition, they will demonstrate series and parallel circuits as well as explain the advantage and disadvantages of each circuit. 

Be sure to take good notes.

Circuits: These are the “S” in WSQ. You must have them under your video notes completed by the due date on the Unit Plan.


1. If two charges repel each other, the two charges must be


positive and positive.


negative and negative.


positive and negative.


Either (a) or (c)

2. Examine the wires below and answer the question that follows.


Which wire has the greatest resistance?


Wire A


Wire B


They both have the same resistance.


It cannot be determined from the information given.

3. How is the shock you receive from a metal doorknob similar to a bolt of lightning?

4. Discuss the difference between a conductor and an insulator as they are used in electricity. Give an example of each as they relate to electricity.

5. How does increasing the voltage affect the current?

6. What are some advantages and disadvantages of series circuits and parallel circuits.

7. In a series circuit, what would happen the the intensity (brightness) of the circuit it another light was added?

8. In a parallel what would happen the the intensity (brightness) of the circuit it another light was added?

9. What, exactly, is a short circuit? What does it mean if a circuit becomes shorted? How does this differ from an open circuit?

10. Why is a fuse so important in a circuit breaker?

11. Describe the relationships of resistance, voltage, and current.

12. Explain the analogy of a hose with water when discussing resistance, voltage, and current. Use your own words.

13.  What is the difference between DC and AC electricity? What are some examples of DC and AC in your house?

14. How much current is in a circuit that includes a 9V battery and a bulb with a resistance of 3 ohms?

15.  A portable CD player uses two 1.5 V batteries. If the current in the CD player is 2 A, what is its resistance?

Question- asking Higher Order Thinking (HOT) questions; use the following as your guide:

1. A question that you are still confused about (be specific, include which part of the video, etc)
2. A question that connects the videos together (i.e. asking about the relationship between the content)
3. A question you think you know the answer to, but you want to challenge your classmates with
