1. Agenda: Unit Test Feb 11. Do this:

2. Standard:
Demonstrate the advantages and
disadvantages of series and parallel
circuits and how they transfer energy.
What am I learning today?
How does electricity flow to make
things happen around the house?

3. How will I know I learned it?
I will summarize my Cornell notes

4. What is the difference between static electricity
and current electricity?

5. What is the difference between static electricity
and current electricity?
Static electricity is stationary or collects on
the surface of an object, whereas current electricity is flowing very rapidly through a conductor.

6. Demonstration:Van Der Graff Generator
Demonstration:Van Der Graff Generator. Record observations and explanations.

7. Why does electricity flow
in currents?

8. Current Electricity Electric forces arise from the presence of
an unbalance in electric charge.
Electric Current is the flow of electric charges.
Electricity always flows from a negative pole
(excess electrons) to a positive pole
(deficient in electrons).

9. Flowing currents of electricity are like flowing currents of water.
What makes the water flow in figure A? Apply this answer to figure B using negative charges instead of water.

10. Demonstration: Record your observations and explanations

11. How are the two types of circuits similar and different?

12. Circuits
There are two types
Series and Parallel.

13. Series Circuits Has only one path for electricity to flow
If any part of the circuit is broken, then all lights will go off.
Ex’s: Christmas tree lights
In a series circuit, the light bulbs are DEPENDENT of each other.
It is like adding pinches to a hose.
Draw this
Circuit
In your
Notes!!!

14. Series Current only takes one path for electrons
Current flows through every part of the circuit

15. Parallel Circuits Has multiple paths for electricity to flow
If any part of the circuit is broken, the remaining lights will stay on.
Example: your home!!
In parallel circuits, the light bulbs are INDEPENDENT of each other.
They have no effect on each other.
Draw this
Circuit
In your
Notes!!!

16. Parallel Circuits Has at least one point where current divides
More than one path for current to flow
Paths are also known as branches

17. Demonstration: Record observations and explanations
