How does electricity move?
It flows.
100
What is lightening?
Nature's electricial discharges.
100
What device can open or close a circuit?
A switch.
100
What is a conductor?
A material in which electricity can flow easily.
200
What to unlike charges do?
Attract
200
What can electricity flow through?
A circuit.
200
What kind of charge gathers on the bottom of clouds?
Negative Charges.
200
What kind of circuit will shut off a bulb if any part of the circuit is opened?
A series circuit.
200
What is a fuse?
A fuse can keep a home safe by opening an overloaded circuit.
300
What happens when wool is rubbed against a balloon?
It gathers a negative charge.
300
What are circuits made of?
Materials called conductors.
300
What charge is the ground outside?
The charge on the ground is positive.
300
What kind of circuit will not shut off all the light bulbs even if part of the circuit is disrupted?
A parallel circuit.
300
What is an insulator?
An insulator is a material that electricity can not flow through easily. They are often used to keep electricity away from people.
400
What happens if a balloon is rubbed with wool giving it a negative charge and then it is put near a positively charged wall?
It will attract.
400
What materials are good conductors made of?
Metals, especially copper, make good conductors.
400
What other positively charged objects attract lightening?
Lightening rods, antennas, and trees all attract lightening.
400
How many paths does electricity have to flow through in a series circuit?
There is only one path for the electricity to flow through.
400
What is an electric circuit?
An electric circuit is a path in which electricity can flow.
500
The gathering of charges on the surface of an object is called what?
Static Electricity
500
What materials do not make good conductors?
Plastic, wood, and fabrics are not good conductors and will not complete a circuit.
500
How does lightening occur?
Lightening occurs when the negative charges on a cloud jump to meet the positive charges that are on the ground.
500
How many paths does electricity have to flow through in a parallel circuit?
A parallel circuit has at least two paths for electricity to flow through.
500
What is an electric discharge?
Electric discharges occur when electric charges are given off or released. Examples include: lightening or electric shocks.
