What is a circuit?

• A circuit is a type of geometric shape.

• A circuit is an open loop through which an electric current can flow.

• A circuit is a musical performance.

• A circuit is a closed loop through which an electric current can flow.

Name one example of a conductor.

• Gold

• Copper

• Silver

• Aluminum

Explain the role of conductors in an electrical circuit.

• Conductors slow down the movement of electric charge in an electrical circuit.

• Conductors generate electric charge in an electrical circuit.

• Conductors play a crucial role in facilitating the movement of electric charge in an electrical circuit.

• Conductors absorb electric charge in an electrical circuit.

What are insulators?

• Insulators are materials that are highly reactive with other substances.

• Insulators are materials that conduct electricity well.

• Insulators are materials that do not easily allow the flow of electricity or heat.

• Insulators are materials that are transparent to light.

Provide an example of an insulator.

• Metal

• Plastic

• Glass

• Rubber

How do insulators differ from conductors in terms of electricity?

• Insulators facilitate the flow of electricity, while conductors prevent the flow of electricity.

• Insulators and conductors have no difference in terms of electricity.

• Insulators are used for heating purposes, while conductors are used for cooling purposes.

• Insulators prevent the flow of electricity, while conductors facilitate the flow of electricity.

Why is it important to have a complete circuit for electricity to flow?

• To reduce the voltage in the circuit

• To allow electricity to flow continuously and complete the path for current to travel.

• To increase the resistance in the circuit

• To prevent the flow of electricity

Describe the flow of electricity in a closed circuit.

• Electricity flows from the positive terminal to the negative terminal in a closed circuit.

• Electricity flows randomly within the circuit.

• Electricity flows only when the circuit is open.

• Electricity flows from the negative terminal of the power source through the circuit to the positive terminal.

What happens when there is a break in a circuit?

• The circuit becomes more efficient

• The flow of electricity is interrupted.

• The flow of electricity increases

• The circuit becomes safer

How can you test if a material is a conductor or an insulator?

• Use a simple circuit with a battery, wires, and a light bulb. Connect the material to the circuit and observe if the light bulb lights up.

• Drop the material in water and see if it floats or sinks

• Rub the material against a magnet and observe if it attracts or repels

• Measure the temperature of the material and see if it changes when connected to a circuit
