The Global Positioning System (GPS), is currently the only fully-functional satellite navigation system. More than two dozen GPS satellites are in medium Earth orbit, transmitting signals allowing GPS receivers to determine the receiver's location, speed and direction.

GPS units are navigational systems, like Handheld units are available in stores and on the internet. Leading brands include: Basic GPS functions are simple to teach Students love using the technology!

What is Geocaching Anyway? People create small caches (boxes, containers) & hide them using GPS coordinates. You can log them online. Some caches have themes, but it is not necessary Caches include items inside for people to take or trade. Logbooks are included so geocachers can sign in when they find the geocache.

Creating A Geocache You need an airtight, waterproof container. Rubbermaid, Ammo Boxes No glass jars Need to camouflage the geocache Colored duct tape from sporting goods supply Fake leaves, moss, twigs or other camouflage Get permission if you are leaving a cache on someone else’s property.

Example In our project, each class chose a theme: Science – animals Math – puzzles World Cultures - countries Students worked in pairs to create a geocache based on their theme.

Each pair was required to provide: A list of clues about the theme. A list of clues about the hidden location Items in the box based on the theme. Students hid the geocaches using handheld GPS units & provided each teacher with the coordinates. Classes rotated hiding and finding the geocaches on school property. Parent volunteers were used to help monitor student behavior.
