What is an electrical charge?
it is a property of matter
what happens when you have a positive and negative charge?
They attract or pull each other
what does it mean when there's a buildup?
it means that it has more of one kind of charge than the other.
what happens when you shuffle across a carpet and touch a doorknob?
You can get an electrical shock
what can be a conductor?
Metals (copper, silver, etc.)
ALSO People!
what does neutral mean?
it means it has no overall electrical charge
what happens when you have a positive with a positive?
They repel/push away from eachother
True or false
Charged particles can move between objects when the objects touch.
True
What is lightning?
It is the discharge of static electricity inside a storm cloud.
What are some examples of Insulators?
Wood, Rubber, Plastic, and Glass
what is static electricity?
it is the buildup of electrical charges on an object
what happens when you have a negative with a negative?
They repel/push away from eachother
what does rubbing objects together do?
it can cause them to touch in more places and produce a larger buildup of charge.
How does lightning form?
1. Negative charges build up at the bottom of the cloud.
2. Positive charges build up on the surface of the ground
3. Negative charges move as a discharge to the positive ground.
You can get shocked
what is a discharge?
it is the movement of static electricity from one object to another.
what are the two different types of charges?
Positive and Negative
what happens when you hold a negatively charged balloon near a wall?
It repels the negative charges in the wall, but can also attract the positive charges in the wall (making the balloon stick to the wall)
Lightning Safety
If you are far away from any shelter, what should you do if you're outside while lightning is striking?
Go to the lowest point and crouch down, lightning often hits the tallest object in an area.
what's the difference between a conductor and an insulator?
Conductors allow the electricity to flow through easily and insulators don't.
what is the difference between an insulator and a conductor?
Insulators: are materials that DO NOT let charges flow through them easily
Conductors: are materials THAT LET charges flow through them easily.
All matter is made up of tiny particles, some can be ________ others can be ____________
positive
negative
