Exploration is not only part of every society; it is one of the basic attributes of human nature. Study of past exploration enables students to learn from the experience of others by recognizing their contributions, as well as the dangers they faced. The Lewis and Clark Expedition is appropriate because of the importance it played in history.

The book Seaman, the dog who explored the west with Lewis and Clark by Gail Langer Karwoski; The Oregon Trail Diary of Hattie Campbell by Kristiana Gregory is incorporated into the unit.
