Conductors and Insulators

What is the difference between a conductor and an insulator?

• An insulator allows electricity to flow through it easily and a conductor does not
• A conductor allows electricity to flow through it easily and an insulator does not.
• An insulator is magnetic and a conductor is not
• A conductor is magnetic and an insulator is not

What object would best complete this circuit?

• A battery
• a peice of yarn
• an insulator
• a conductor

The plastic covering is there to:

• Provide a conductor for electrical energy to flow.
• Provide an insulator so that electrical energy will not pass outside of the wires.
• Provide a conductor so that electrical energy can NOT flow.
• Provide an insulator so that electrical energy can flow.

Olivia wanted to complete her circuit with a conductor.  What object is her best option?

• Wood stick
• Glass bead
• Aluminum foil
• Styrofoam

You know that the object connected to the wires is a conductor because:

• The light bulb is glowing bright.
• It's a complete circuit.
• It's a closed circuit.
• The object is shiny.

Tatrys knows that the light bulb will turn on because the circuit:

• includes an insulator.
• is an open circuit.
• makes a complete path.
• includes a battery.

The handle of a frying pan is often coated in rubber because rubber provides...

• Heat insulation
• Heat conduction
• A low melting point
• A nonstick surface
