The outdoor activity using a GPS receiver, mobile device or other navigational devices to hide and find caches, are also known as geocaches, around the world it is known as geocaching. It is a recreational activity.

Another outdoor sport, geodashing involves participants using GPS receivers to locate and visit “dashpoints” (or “waypoints”) that have been randomly selected across the world and report their discoveries. The purpose of the game is to visit as many of these waypoints as possible around the world.

Where geocaching allows participants to leave things at the location points, geodashing does not. The only purpose of geodashing is to reach the locations within the specified time limit.

In the late 19th and early 20th centuries, a popular educational movement known as the nature study movement was formed in America. Its goal was to unite personal and spiritual experiences of interacting with nature and scientific investigation. Several teachers, scientists and leaders across America were in agreement that nature study was a valuable experience. This led to the subject becoming an integral part of how the environment and nature were investigated and studied in the USA in the early parts of the 20th century. Public support was given to this idea by scientists who also made the contribution to the development of a curriculum and courses. This group was especially popular in many institutions; scientists also felt “that students needed more and better preparation in secondary and primary schools”. In addition to the evolution of school curriculums, the entire education system itself was changing. In large urban areas such as New York, city populations continued to rise and students were officially required to attend school for a specific number of hours and days per year as determined by legislation.
