INTRODUCTION TO THE AMERICAN WEST TODAY
Summary
Two centuries after the expedition, many changes have taken place
along the Lewis and Clark Trail. The land, flora and fauna, and
native societies in each ecological zone have been altered to one
degree or another. In this lesson and its related activity, students
research the nature and causes of these changes, particularly those
brought about by human intervention.

.A Word For Teacher About Using This Curriculum Guide
Lesson plans and activities in this curriculum guide have been planned
to accommodate a wide range of student interests and capabilities
rather than imposing a rigid age/grade structure upon the materials.
We encourage teachers to adapt the materials according to the needs,
interests, and capabilities of their classes. Even the diagram below
should be taken as an approximation. After all, no one knows your
students better than you do.
