How Does Electricity Flow?

• 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.
• Just as runners follow a path, electrons follow a
  path.

Building an Electric Circuit

• You will need
• One battery
• Electrical tape
• Bare copper wire
• Scissors
• Miniature light bulb

4
How to Build an Electric Circuit

• 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.

5
Building an Electric Circuit

• 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.

6
Building an Electric Circuit

• 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?

How Does it Work?

• 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.

How Does it Work?

• 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?
