This content resource, Map Machine from National Geographic is a lot of fun. When reviewing this resource, I was able to zoom in on our local town to a higher level than Google Maps. However, I was able to tell when I zoomed in that the map was outdated, due to the nonexistence of recent construction on the map. Using Map Machine you are able to zoom into almost anywhere in the world and navigate or print out maps. You are able to look at road, satellite, topographic, weather, natural disaster, farming and natural resource, population density, U.S. boundary, or trip planning maps. This resource has an addictive quality about it that will have many students enthralled in the process of exploring maps if given a chance. I was able to get a really good view of Ohio Stadium when I zoomed in on Columbus, Ohio. This resource along with the wealth of resources available at National Geographic should be a part of every social studies teachers toolbox.
