Latitude/Longitude and GPS Basics

  • Longitude and Latitude Basics
  • The Find Your Longitude game helps make the connection between the Earth's rotation and time zones.
  • Play the The New Navigation game to learn how GPS receivers determine your location on Earth. This is a slimmed down explanation of how GPS receivers work. Includes nice graphics — including a visual that teachers can relate to Venn Diagrams.

Geocaching

Geocaching is a world wide treasure hunt in which people hide a "treasure" and then post the longitude and latitude coordinates, along with a little hint so that others can find it. Once found, the finder signs a log sheet and, if something is there to take, removes a trinket and leaves a trinket for the next finder. There are thousands of caches in Oregon; caches can be found all over the world!
