How come you don’t get shocked when you touch most things?
they are NEUTRAL
200
Why do people get shocked/zapped when they touch some objects?
objects are NOT NEUTRAL, and the MOVEMENT OF ELECTRONS occur to make objects neutral again
200
How do you get an “electric charge” on an object?
you rub 2 things together to get electrons to move

What's an electric power generator? 2 examples?
object that supplies electricity/electrons
1. battery
2. outlet

-conductor
-insulator
resistance - light bulb
conductor - copper in wire
insulator - rubber on wire

what are 2 ways we can OPEN a circuit?
1. turn OFF switch
2. take part of circuit OUT
300
What is the difference between a series and a parallel circuit?
series- ONE PATH
parallel- MULTIPLE (OWN) PATH
300
What are 2 ways electricity can harm you??
1. burn
2. stop the heart

What area is magnetism felt the strongest on a magnet?
The poles: N and S
400
What is the difference between:
-Magnetism
-Magnetic Field
-Magnetism: push or pull force on magnet
-Magnetic Field: space/area where magnetism is FELT
400
What first suggested that Earth is a magnet? What's the name of the scientist who made the compass?

A magnet wrapped in coiled wire is called a....
GENERATOR
400
Who put a battery in wire and realized it was magnetic? How did he know?
Hans Oersted
needle of compass moved TOWARDS WIRE
500
What is the definition of
-resistance
-conductor
-insulator
-resistance: opposes electricity and turns into HEAT ENERGY
-conductor: electricity flow easily
-insulator: opposes electricity (not flow easily)
500
Definition of:
-Magnet
-Magnetism
-Magnetic Field
-Magnet: attract iron/steel/metal to it
-Magnetism: push or pull force on magnet
-Magnetic Field: space/area where magnetism is
500
What are the northern lights and where do they occur?
North USA and Canada…
-Particles from sun are pulled to Earth’s magnetic poles and
- React with gas in air and make colored lights in sky!
500
A generator can be powered by what?
wind, water, nuclear power
500
What's an electromagnet? What is a way we can make it STRONGER? WHY???
The TEMPORARY magnet made when electric current flows in a coiled wire
IF WE PUT A NAIL with the battery, magnetism will be stronger due to nail being magnetic itself.
