1. Explaining Electricity
L/O – To understand how models can be used to explain electricity

2. What are the symbols for these components?
Voltmeter
Ammeter
Bulb
Switch
Cell
Battery

3. How is a power station like a battery?
Mine = Battery
The mine provides coal which powers the power station
The battery give the electrons the energy
Trucks = Electrons
The trucks carry coal to the power station
The electrons carry electricity around the circuit
What represents the battery?
What represents the bulb?
What represents the wires?
What represents the electrons?
Power station = Bulb
The coal allows the power stations to work
The energy carried by the electrons lights the bulb
The empty trucks return to the mine to pick up more coal
The electrons return to the battery to pick up more energy

4. How is a power station like a battery?
What would happen if you added another mine?
What does this tell you about adding more batteries?
What would happen if you added another power station?
What does this tell you about adding more bulbs?
How could you represent a bulb?
How could you measure the energy the electrons are carrying?
How could you measure the amount of electrons flowing around?

5. How is a power station like a battery?
What would happen if you added another mine?
What does this tell you about adding more batteries?
What would happen if you added another power station?
What does this tell you about adding more bulbs?
How could you measure the energy the electrons are carrying?
How could you measure the amount of electrons flowing around?

6. Once you have designed your model, explain what would happen if you
Task
Your task is to design your own model for electricity
Once you have designed your model, explain what would happen if you
Added a switch
Added another battery
Added another bulb
Made it into a parallel circuit
