Examples of Static
Electricity• Laundry sticking together • Hair standing up after jumping on a
trampoline• Combing or brushing clean dry hair• Getting “shocked” by someone• Shuffling across carpet • Lightning

How do you know
static electricity is present
• A crackling sound
• A spark can be seen and felt
• Items cling together

Lightning is a giant spark of static electricity thatforms in the clouds. Lightning is caused by the
movementof positive and negative charges toward one another.
During a storm the particles in a cloud become statically charged by the action of the wind blowing
Them around the cloud. The stronger source of static electricity moves towards the weaker source causing
the flash that we see as lightning.
What is Lightning?

Static Electricity:
Builds charges in one place
Current Electricity:A discharge of electricity that
moves along a pathway

Incomplete Circuit:
A piece not connected – the light is off
Complete Circuit:A finished circuit with every pieceattached – the light is on

Power Source:
The source of electricity = battery
Pathway:The path the electricity follows = wire
Definitions

Load:
Uses the electricity = light bulb
Switch:Opens and closes the pathway =
switch

How does changing the power
source affect the circuit?
The more batteries there are, the brighter the light
Power Source

How does changing the pathway
affect the circuit?
The more wires there are, the light doesn’t change
Pathway Source

How does changing the switch
affect the circuit?
All switches have to be in the on position in order for the light to turn
on
