• It's a closed circuit.
• The object is shiny.

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

• Wood stick
• Glass bead
• Aluminum foil
• Styrofoam

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.
