World Geography at Wilbur Wright College seeks to have students recognize and understand human efforts to understand Earth.
Connection with the Curriculum
Both latitude and longitude help us understand Earth. While latitude is based on natural and physical observations, longitude resulted from superimposing a human and cultural system over Earth. The two systems represent human quests to make life on Earth more manageable. Understanding that latitude, longitude and time zones are human conventions based on observations of Earth phenomena leads to being a more geographically informed person.
The Prime Meridian was located at the Greenwich, England Observatory by international agreement and is the basis of world time zones that are central to human activity. Understanding how the system was developed and how we use time zones today is a basic geographic accomplishment. Maps and mapping techniques are extremely useful in portraying Earth at local and global scales.
Viewing recent color slides of a trip to Greenwich, England provides the reinforcement after completing a time zone activity and provides occasion to discuss the new millennium.
