Students are familiar with the term neighborhood used to describe the people or things that live near them. In this inquiry investigation, students use a variety of investigative tools – including global positioning system (GPS) units – to learn about local ecology . Students will understand that the ecology of localized areas differs from place to place, much like a neighborhood, and they will use global positioning to mark various locations as addresses within their ecological neighborhood or, as it is called in this exercise, their ecohood.
