Earth's Magnetic field, Presentation!

  1. Dec 17, 2009 #1

    I have a presentation next week "Earth's Magnetic field" and I was wondering how to start?? what should the introduction be about?? magnetism??? earth's structure?? or what??

    Any creative ideas?? I want it to be something interesting and grab people's attention :D

    Thanks in advance!

    P.S I didn't know where else to post my thread, hopefully this is the right place!

    Start at your audience's level and work to your topic. If they don't know/need a refresher in magnetism, start there. Same with earth's structure. Which one you start with depends on the story you're trying to tell with your presentation.

    Homework help, (introductory physics or other sciences), which is another sub-forum in the science education section of physicsforum.
