In terms of global change, our premise is that Kelsey Island is enclosed in Long Island Sound in the way that Long Island Sound is enclosed in the Atlantic Coast and the Atlantic Coast is enclosed in the Atlantic Ocean. This ocean is finally enclosed in the world. These relationships present the opportunity of a fractal relationship: a microcosm within a microcosm. Changes in the environment taking place in Kelsey Island reflect changes in the environment that have taken place in Long Island Sound. At the same time, these changes reflect what has been going on in the larger picture of the Atlantic coast and the world in general. Man-made changes to the environment as well as changes that have taken place due to the forces of nature have affected the island, the Sound and the Atlantic Coast as well. For example, we might think of the changes in sea level during the last few thousand years due to the last glaciation and the changes in temperature when these majestic bodies of ice moved and melted.
In this unit, students participate in a series of field trips that culminate in the construction of a map of the island.
