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.
Three Questions to Build From… Where were you born? Where was your most favorite vacation? Where is the furthest away from home you have ever been?
Why Latitude & Longitude? (Location. Location. Location.) If we wanted to meet in Barcelona for a cold beverage, how best could we pinpoint a location? How about in NYC? Kansas? 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.
