Interesting revelations en route to teaching the use of GPS receivers to middle schoolers: 1.Most students (and a good number of adults) do not have a good grasp of the concepts of latitude and longitude. 2.Following a GPS without at least some map- reading ability can be trouble. 3.Many folks have an interesting concept of how GPS units work.

If we wanted to plot attributes (rainfall amounts, elevation, land use) onto a GIS map, how best could we pinpoint each location?
Latitude & Longitude create a grid system which gives every physical location its own specific name or marker.
