Vocabulary
100
A material that allows electricity to flow easily.
What is...
a conductor?
100
A material that does NOT allow electricity to flow easily.
What is...
an insulator?
100
This type of circuit lets electricity flow all the way around without any breaks.
What is...
a closed circuit?
100
The presence and flow of an electric charge
What is...
Electricity
200
Which material is the BEST conductor of electricity?
What is...
Metal
200
What is...
C. Rubber is a good insulator and prevents the flow of electrical energy.
200
This type of circuit has a break that stops electricity from flowing.
What is...
an open circuit?
200
Energy that causes a transfer of heat between materials
What is...
Thermal Energy
300
What is...
conductor
300
You want to stop electricity from flowing. Which material should you choose?
What is..
Rubber, plastic, wood, etc.
300
This gives energy to the circuit and pushes the electrons.
What is...
a battery?
300
Energy resulting from the flow of electric charge through a conductor
What is...
Electrical Energy
400
How is a conductor different from an insulator?
What is...
A conductor allows heat/electricity to travel through it easily.
400
Why is it important for power lines to be covered in thick plastic?
What is...
So electricity doesn’t escape—plastic is an insulator.
400
Describe how energy moves through a complete circuit.
What is...
Battery → wires → bulb → back to the battery.
400
A pathway that allows an electric current to flow freely
What is...
Closed Circuit
500
What is the purpose of the copper inside of a wire?
What is...
It carries the electrical energy from one place to another
500
What is the purpose of an insulator?
What is...
An insulator does not let heat/eledctricity pass through it easily.
500
Tell me something about this circuit
What is...
The switch is open
500
The flow of electrical energy through a circuit
What is...
Electric Current
