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.

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.

What part of a circuit controls the flow of electricity?

• wire
• switch
• battery
• motor

Which of the following best explains an electric current?

• An electric current is the flow of positive charges in a circuit.

• An electric current is the flow of atoms in a circuit.

• An electric current is the flow of electrons in a circuit.

• An electric current is the flow of neutrons in a circuit.

What is tap water?

• Water that comes from the tap.

• Water with salts.

• Water that we drink.
