Geocaching is a growing modernized scavenger hunt involving tiny trinkets hidden all over the world and identified by GPS coordinates. It creates an entirely new way to explore new and familiar environments. When a geocaher finds the gem he/she has been searching for, there are ways to prove he/she did so including anything from simply signing a piece of paper in a small jar, or solving a riddle and posting the answer on the geocaching website. It's not only educational, but fun too!
Not only has GPS technology created a fun way for us bored college students to wander around looking for hidden things, but it also poses to be a great aid to environmental research. Today marine biologists are tagging sharks with GPS locators to monitor their behaviors and migrations patterns. This allows us to no only have potentially safer beaches, but also understand the animals in entirely new ways.
