*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?

*Definitions
Static Electricity:Builds charges in one place
Current Electricity:A discharge of electricity that
moves along a pathway
![Page 11: Changing Circuits * Electricity. Standard Students will understand features of static and current electricity and that electricity is a form of energy.](https://reader035.fdocuments.in/reader035/viewer/2022062306/5a4d1b127f8b9ab05998ffdb/html5/thumbnails/11.jpg)
*Definitions
Incomplete Circuit:A piece not connected – the light is
off
Complete Circuit:A finished circuit with every pieceattached – the light is on

*Definitions
Power Source:The source of electricity = battery
Pathway:The path the electricity follows = wire
![Page 13: Changing Circuits * Electricity. Standard Students will understand features of static and current electricity and that electricity is a form of energy.](https://reader035.fdocuments.in/reader035/viewer/2022062306/5a4d1b127f8b9ab05998ffdb/html5/thumbnails/13.jpg)
*Definitions
Load:Uses the electricity = light bulb
Switch:Opens and closes the pathway =
switch
