What is the term used to describe a nail (or other item) that acts as a magnet when rubbed against a magnet for a short period of time?
A temporary magnet.
100
What device opens and closes a circuit?
switch
100
This term refers to materials that allow electricity to flow through them.
Conductors
100
Is a paperclip an example of a conductor or an insulator? Explain your answer.
Conductor. A paperclip allows the electricity to flow through it when placed in a closed circuit.
200
A magnet has a ________ and a __________ pole.
North and South
200
A specific kind of force where objects "stick" together.
Magnetism
200
What is an insulator?
A material that does not allow electricity to flow through it.
200
This term refers to where the circuit receives its electricity. Give an example of this term in our experiments in class.
electricity source. D-cell
200
This term refers to materials that do not allow electricity to flow through them.
Insulators
300
What term is used to describe when two magnets stick together?
Attract.
300
A push or a pull.
force
300
What type of circuit allows a bulb to be taken out and a second bulb will stay lit?
parallel circuit
300
The motors and the light bulbs are examples of electricity ______________________ .
receivers
300
What is the part of the light bulb that is heated and produces light?
filament
400
What term is used to describe when two magnets push apart from each other?
repel
400
A student placed two magnets next to each other on a table. The north side of one magnet was facing the north side of the other magnet. What will most likely happen when the student lets go of the two magnets?
Repel (or push away from each other).
400
What is the term that is used to describe a way that a circuit can be drawn on a piece of paper?
schematic diagram
400
In a ______________ circuit, there is more than one path for the electricity to flow.
parallel circuit
400
A coil of wire, usually wound around a core of iron or steel, which produces a magnetic field when electricity flows through it is called an __________________________.
electromagnet
500
The force of attraction between 2 magnets ___________ with distance.
decreases (becomes weaker)
500

What is the term that describes an imbalance of charges within or on the surface of a material? This term is often caused by friction.

Static electricity

500

In a ___________ circuit, there is only one path for the electricity to flow.

series circuit

500
What type of electricity can be described as positive and negative electric charges separated from each other and are not moving around?
Static Electricity
500

What is the purpose of a circuit breaker?

To prevent damage to a circuit when a circuit is detected to have a short circuit or an overload. The circuit breaker will stop the flow of electricity temporarily until the circuit is fixed (reset).
