Conductors and Insulators

Conductors and Insulators

How do they compare?

Conductor

• Atoms: Electrons are loosely attached to their atoms

• Electron Behavior: Move easily from one atom to another atom

• Purpose: Connect all parts of a circuit to allow electrons to flow

Multiple Choice

Why do electrons move so easily in conductors?

• have loose electrons

• have tight electrons

• have exploding electrons

Multiple Choice

What is the purpose of conductors in an electric circuit?

• make the circuit faster

• connect parts of circuit

• stop the flow of electricity

Metals - Good Conductors

• Copper

• Iron

• Silver

• Aluminum

• People

Multiple Choice

What type of matter makes good conductors?

• Gases

• Nonmetals

• Metals

Multiple Choice

Aluminum cans are examples of good conductors.

• True

• False

Insulators

• Atoms: Electrons are bound tightly to their atoms

• Electron Behavior: Do not move easily from one atom to another atom

• Purpose: Protect people from becoming part of a circuit

Multiple Choice

Why do insulators not allow the flow of electricity?

• have loose electrons

• have tight electrons

• have happy electrons

Multiple Choice

What is the purpose of insulators in a circuit?

• connect parts of circuit

• protect people from electricity

• to make the wire look pretty

Nonmetals - Good Insulators

• Wood/Paper

• Glass

• Plastic

• Rubber

• Cloth

• Foam

• Ceramic/Clay

Multiple Choice

What type of matter makes good insulators?

• people

• nonmetals

• metals

Multiple Choice

Glass is an example of an insulator.

• True

• False

Conductors and Insulators Comparison

Multiple Choice

Using a conductor in a circuit will

• allow electricity to flow

• will not allow electricity to flow

• makes the circuit disappear

Multiple Choice

If you place an insulator in an open circuit, it will

• complete the circuit

• destroy the circuit

• not allow electricity to flow
