  1. How Does Electricity Flow? Electricity & Magnetism Science Instructor: Miss Aartman

  2. 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.

  3. 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?

  7. 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.

  8. 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!!!!!!!
