1. Electricity
SPI
Identify how simple circuits are associated with the transfer of electrical energy when heat, light, sound, and chemical changes are produced.

2. Electricity is the constant flow of electrons
What Is Electricity?
Electricity is the constant flow of electrons

3. Kinds of Electricity Static Examples
An electric charge that collects or builds up on the surface of an object
Examples
Shocking
Lightening

4. Kinds of Electricity Current
The flow of electric charges carried through a material such as wire or other conductors
Examples
Power lines
Computers
Appliances

5. Circuits
What are they?
Circuits are a path along which electricity moves

6. Simple Circuits Simple Circuits have 3 parts – energy source
Wires (conductors)
Object it operates (load)

7. Simple Circuits
energy source
load
conductors

8. Switches
Switches are used to open and close the circuit. A switch allows two pieces of metal to touch and electrons to flow.

9. Switches

10. Working Circuits
Closed Circuit These circuits have a complete path to follow. There are no openings in the path.

11. Working Circuits Open Circuit
These circuits do not have a complete path to follow. The power cannot pass from the source to the receiver.

12. Working Circuits
Closed
Open

13. Kinds of Circuits Series
These circuits have one path for electricity to flow through.
*Some Christmas lights
*Flashlight

14. Kinds of Circuits Parallel
These circuits have more than one path for electricity to flow through.
*Your house
*Power lines

15. Series vs. Parallel Circuits

16. Electricity Know what it is Know the different kinds
Know about the different kinds of circuits
Know about conductors and insulators
