Electrical & Thermal Conductors
What is an electrical conductor?
An Electrical conductor allows electricity to pass through
What is a thermal insulator?
A thermal insulator does not allow heat to pass through
How many forms of energy are there? Name them.
There are 5: Mechanical, Electrical, Light, Thermal, Sound
What is conductivity?
Conductivity is a material's ability to let energy flow
Please recite the red and green light rhyme for conductors and insulators.
If green means go, conductors will flow
If red means stop or slow, insulators will not flow
What is a thermal conductor?
A thermal conductor allows heat to pass through
What is an electrical insulator?
An electrical insulator does not allow electricity to pass through
What is energy?
Energy is the ability to do work and cause change.
What is a conductor?
A conductor allows energy to flow
True or False: Insulators does not allow and allows energy to pass through.
False: Insulators do not allow energy to pass through.
Electrical Conductor? What kind of material allows electricity to pass through?

What is an insulator?
An insulator does not allow energy to flow.
True or false: Solar energy is a part of the five forms of energy.
False: Solar energy is not a part of the five forms of energy.
Thermal Conductor: What kind of material allows heat to pass through?
Metals: Copper, Iron, Steel, Gold, Aluminum
Electrical insulator: What kind of material does not allow electricity to pass through?
