While checking out the geocaching website, I saw one of the thousands of apps for an iPhone - Geocaching with the iPhone- only $10! Even in this small town of about 2500 people, there are geocaches! Going out this morning to check out the one that is only .3 miles from my home and on the way to school. Ideas fly with using this technology for education.

And the list goes on.
There are simple geocache handhelds on the website, too. Working in groups of 2-5, students can share the jobs and experience collaborative learning as they locate, define, process, and record information.
