### How Does Electricity Flow?

Electricity & Magnetism

Science

Instructor: Miss Aartman

• Electricity usually flows in a loop.

• This loop is called an electric circuit.

• In an electric circuit, electrons flow through a complete path and return to their starting point.

You will need:

• One battery

• Electrical tape

• Bare copper wire

• Scissors

• Miniature light bulb

Working in a group of three: Step one

• Batteries have two parts a positive end and a negative end.

• Draw a diagram of the battery.

Step two:

• Tape one end of one piece of covered wire to the bottom end of the battery.

• Tape one end of the other piece of wire to the top end of the battery.

Step three

• Touch the free ends of both wires to the light bulb.

• Touch one wire to the base of the bulb and the other to the metal piece around the side of the bulb.

• What happens to the bulb?

• Electrons started flowing from the bottom of the battery through the copper wire.

• Then they flowed into the bulb and made it light up!

• The electrons then flowed from the bulb through the other copper wire that is connected to the top of the battery.

• The electrons traveled in a loop, or through a complete circuit.

• Copper wire allows electrons to flow freely.

• Anything that allows electrons to flow is called a conductor.

• Things that do not allow electrons to flow are called insulators.

• How can you find out whether something is a conductor or an insulator?

• Find out next time!!!!!!!
