Been working with elementary students for 15 years. Always looking for new ways to engage students with technology.
GPS, or Global Position System, is a satellite-based navigation system made up of 24 satellites (plus some spares) orbiting the Earth. First used by the military, the US government made the system available for the world to use in 2000. The 24 satellites orbit about 12,000 miles above Earth and travel about 7,000 miles an hour. Each satellite sends signals back to Earth. Signals can pass through clouds, glass and plastic but not solid objects like mountains and buildings. The Clinton Administration unlocked the satellites for public use in 2000.
A GPS Receiver receives signals from GPS satellites and allows you to find your exact location on Earth. The receiver must lock in at least three signals to work – this gives you information on latitude, longitude, and altitude. The more signals you get the more accurate your position. A GPS receiver only works outdoors and is less reliable around tall buildings like classroom walls and tree groves that may block satellite signals. (2 nd Pic) Cloudy days can also effect signals. It is important to find an open area if possible when turning on the GPS receiver.
Geocaching is an engaging, hands-on outdoor scavenger hunt that encourages inquiry and problem-solving. The word geocaching is made up of two words – geo for geography and cache, a term used for hiding provisions. Using hand-held global positioning systems (GPS), geocachers search for hidden caches in different locations. There are different kinds of a caches. A traditional cache is a box that holds a log book, pencil, and items for trading. Microcaches are small caches that hold just a logbook. An earth cache is a physical place. Isn’t it amazing that in less than 10 years more than 930,000 caches have been hidden in over 100 countries.
The rules of geocaching are simple. There are more rules related to what can actually be placed in caches. They just require a bit of common sense – i.e. no food, weapons, etc.
Educaching takes the concept of geocaching into the classroom. Teachers hide caches related to their curriculum while students search for them – on a school playground, across the school campus, at a local nature park, while on a field trip,– locations for educaches are limitless. In addition, using the Internet and Google Earth allows students to participate in geocaching activities globally. Started in 2000 with 75 cahces were posted online, today there are more than
Educaching allows students to: Take ownership for their learning. Use real world data to encourage high order thinking skills. Collaborate and cooperate when working with a team Increase their understanding of mapping systems, as well as the principles of direction, distance, and location. Construct their own knowledge and share it with others. Make decisions. IT’s FUN!!!!
Educaching allows students to: Create student-centered environments. Present authentic, real-world tasks. Instill in students curiosity about geography, science, mathematics, and the world in which they live. Engage the multiple intelligences. Embed learning in a collaborative, social environment. Integrate the curriculum.
One of the easiest and cheapest ways to get started with geocaching is through the use of travel bugs. A travel bug is an item that can be tracked online at Geocaching.com (free). Each travel bug (dog tag) has its own tracking number stamped on it. This tag is then attached to a small item such as a stuffed toy, key chain or luggage tag and placed inside a cache. Geocachers will move a travel bug from cache to cache in the real world, while you and your students can track its movement online. Travel bugs can be given tasks or missions to complete. It is up to the owner of the bug to decide.
I have released 8 travel bugs in the last year with my students. They have been in 25 states and 3 countries. One has traveled to Paris to see the Eiffel Tower and is on its way back again.
Last year I kept a map in my lab that students got to see each week. Now the map is hanging on a hallway bulletin board for the kids to continue to follow. Part of the website allows you to download .kmz files showing the path of the travel bug.

I began by having students
To kick off a unit on Asia, caches held flags from 12 different countries. Their first task was to use an online flag website to identify their country’s flag. Next, they were asked to use World Book for Kids to research either the geography, people, economy or government of their country. Finally, students composed information paragraphs to add to a class wiki. This wiki will be added to again this year.
