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

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.

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?

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?
  • Find out next time!!!!!!!
