Recap of the first week of school

We started SY 2007-2008 by learning about basic geographical concepts such as longitude and latitude. We watched the video "Lost at Sea: The Search for Longitude." The video portrayed the work of John Harrison, the man who solved the problem of determining longitude at sea. We started learning the skill of making mind maps. We also worked on a crossword puzzle on map basics.
