Storyboard Text

  • Max was waiting with his friend Josh for the bus to take them too school .
  • Hey, max you ready for the science test Mr Ceruti made?  Apparently, its got questions like compare and contrast an electric motor and generator, I don't even know that means.
  • Man, that's easy!  A motor converts electrical energy into mechanical energy, while a generator makes mechanical energy become electrical energy.
  • Really Its that simple?!   
  • Yea it is!  Mr ceurti told me that in the test we would have to give 3 examples of machines that use electric motors .
  • Yea fans, electric drills and electric clocks are just a few machines that use electric motors.
  • And finally what is something that has changed the world that uses an electric motor?
  • An electric drill because most drills used these days are electric and most trade jobs would use them every day.
  • Just so you know how to explain the link between electromagnetism and the functioning of motors and generators, it's just when a wire is moved through the magnetic fields a current goes through it. Say a coil of wire was being spun between the two opposite magnets, there is electricity being generated to make the motor work.
  • I'm just not too sure about how the coal is converted into energy though.
  • its simple man, There's thermal coal that has been put into a fine powder that we burn to produce water (steam) to spin the turbine in the motor.
