Geocaching is a worldwide recreational activity enjoyed by GPS users. It involves a GPS user hiding a "cache" and posting the exact coordinates so other GPS users can come on a "scavenger hunt" to find it. There are caches of all kinds for all ages and are usually placed in interesting locations in your area that you may not know about. The concept of the game can be easily adapted as an engaging way to have students discover concepts and information in any curriculum. With a little work you’ve integrated technology, a little exercise, and whatever topic you want to explore, giving multiple ways to learn subject matter. Use a ‘Multi-Stage Cache’ to test the comprehension of your students from the story your class just read; or perhaps you could have your students cooperatively solve a math puzzle to find the hidden container; or even peruse the ‘EarthCaches’ on Geocaching.com - caches from around the world based on various geology and earth sciences.
