Electricity Conductors and Insulators

Phoebe Kylie from Grade 5 Pearl demonstrates an experiment to show how electricity flows through different materials. She initially uses one battery, which fails to light a bulb due to insufficient voltage. By doubling the batteries, she successfully lights the bulb. She tests various materials like paperclips, coins, and forks, identifying which conduct electricity. The experiment concludes with a discussion on conductors and insulators, highlighting that metals conduct electricity while materials like rubber and paper do not.

What was the purpose of the experiment introduced by Phoebe Kylie?

• To test if all materials can conduct electricity

• To find the best material for making light bulbs

• To create a new type of battery

• To measure the speed of electricity

Why did the initial setup with one battery fail to light the bulb?

• The bulb was not connected properly

• The aluminum foil was not conductive

• The bulb was broken

• The battery voltage was too low

What change was made to successfully light the bulb in the experiment?

• Using a different type of tape

• Using a different bulb

• Adding more aluminum foil

• Doubling the number of batteries

Which of the following materials successfully conducted electricity in the experiment?

• Paper

• Cotton buds

• Paperclip

• Toothpick

Which material did not conduct electricity when tested?

• Coin

• Fork

• Paper

• Spoon

What happened when the spoon with rubber was tested?

• It conducted electricity

• It did not conduct electricity

• It sparked

• It melted

What is a conductor according to the experiment's conclusion?

• A material that stores electricity

• A material that allows electric current to pass through

• A material that blocks electric current

• A material that generates electricity

Which of the following is an example of an insulator mentioned in the conclusion?

• Plastic

• Aluminum

• Copper

• Steel

What is the role of the protective coating on wires?

• To decrease the resistance

• To increase the voltage

• To insulate and prevent electric current from passing

• To conduct electricity

Which material was not tested in the experiment?

• Comb
