Science Inquiry with iPod Sound

A post came across Snapguide titled "Amplify Your iPod's Sound Without a Speaker".  My curiosity had me try it out, and it works.  Then teacher mind set in, and what a good prelude to a science inquiry investigation for your students.

Possible questions to investigate:
  • What height of glass will produce the loudest amplification?
  • What width of glass will produce the loudest amplification?
  • What types of materials produce loudest amplification; glass container, plastic container, etc?
  • How will amplification vary where glass is placed?  On floor versus counter versus top of refridgerator?
  • How will amplification vary if glass is placed next to wall, window, or out in open?
  • How will amplification vary if glass is placed on different surfaces; carpet, counter, paper, etc?
  • Will items in glass have any effect on amplification?

And there are many more questions students will invent.  If you have students investigate these questions, what are your results?  And if you come up with additional question to investigate, what would they be?

    This is awesome! I wonder if this works with iPads as well? I am sure we could come up with some other ideas for testing! Very cool! Thanks for sharing. Can't wait to try it!
