Why does a wire conduct electricity but a string does not?

• Because wires have more atoms than strings

• Because wires are thicker than strings

• Because wires are made of metal and strings are not

• Because the electrons in wires can move freely while in strings they cannot

What is the role of electrons in conductors?

• They disappear

• They create heat

• They move freely from atom to atom

• They stay fixed in one place

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

• By feeling its texture

• By measuring its weight

• By checking its color

• By using a circuit with a light bulb and crocodile clips

What happens if the light bulb turns on when testing a material?

• The material is a conductor

• The material is magnetic

• The material is broken

• The material is an insulator

What is the result when a coin is tested in the circuit?

• The light bulb turns off

• The circuit breaks

• The light bulb flickers

• The light bulb turns on

Which of the following materials is an insulator?

• Metal spoon

• Rubber band

• Tinfoil

• Soda can

What is the result when a glass piece is tested in the circuit?

• The light bulb turns off

• The light bulb turns on

• The light bulb flickers

• The circuit breaks

Which material is a good conductor of electricity?

• Wood

• Plastic

• Metal
