What object would best complete this circuit?

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

What is NOT an example of an insulator in the kitchen?

• An oven mitt
• Pots and pans
• A wooden spoon
• A plastic measuring cup

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.

The metal copper is there to:

• Provide a conductor for energy to flow from one place to another.
• Provide an insulator for energy to flow from one place to another.
• Provide an insulator to slow the flow of energy.
• Provide a conductor so slow the flow of energy.

• Wood stick
• Glass bead
• Aluminum foil
• Styrofoam

Claire wants to complete her circuit with a conductor.  What object is her best option?

• rubber
• a penny
• card board
• plastic spoon

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.

Which is NOT an insulator.

• Wool
• Plastic
• Copper
• Glass
