6.1 Which materials conduct electricity?

What is a conductor of electricity?

• A material that allows electricity to pass through it.

• A material that stops electricity from passing.

• A material that only allows heat to pass.

• A material that glows when electricity touches it.

Which of the following is a conductor?

• Plastic ruler

• Wooden spoon

• Copper wire

• Rubber band

What is an insulator of electricity?

• A material that lets electricity pass through.

• A material that does not let electricity pass through.

• A material that makes electricity stronger.

• A material that only lets heat pass through.

Which of the following is an insulator?

• Iron nail

• Wooden stick

• Aluminum foil

• Paperclip

Why is it important to use a fair test when testing conductors and insulators?

• So we can get random results.

• So we can make sure the results are fair and accurate.

• So we can get different answers each time.

• So we can guess which materials work best.

What safety rule should you always follow when working with electricity?

• Use wet hands to touch electrical wires.

• Never touch electrical wires with bare hands.

• Put metal objects into sockets.

• Play with electrical appliances near water.

What do you call a guess made before an experiment?

• Conclusion

• Prediction

• Observation

• Explanation

If metal objects allow electricity to pass through, what conclusion can you make?

• Metal is a good conductor of electricity.

• Metal is an insulator.

• Electricity does not pass through metal.

• Electricity only passes through rubber.

Why do electricians wear rubber gloves when working with wires?

• Rubber gloves help electricity move faster.

• Rubber gloves stop electricity from passing to their hands.

• Rubber gloves make the wires stronger.

• Rubber gloves change the color of electricity.

If your results do not match your prediction, what should you do?

• Ignore the results and change the answer.

• Write down the results and think about why they are different.

• Change the experiment so the results match your prediction.

• Erase the results and start over.
