Preparing for the Trip

INTRODUCTION TO UNIT

Target Grade Level:
Elementary and Middle School, Grades 4 - 8

This unit focuses on Meriwether Lewis's preparations for the expedition. It uses Lewis's trip to Philadelphia as a foundation for students to consider the idea that life is a journey of discovery. Students will understand some of the challenges inherent in preparing for the unknown and will learn about the preparations necessary for Lewis and Clark's expedition. They will use maps and paintings to gather information about Philadelphia in 1803. By reading primary and secondary documents, students will learn about the people Lewis met with in Philadelphia, and they will discover why each person's area of expertise was deemed important for Lewis's preparation. Students will gather and classify information from documents to determine what items were taken along on the expedition and for what purposes. They will learn how discoveries can be guided and shaped by expectations, supplies, and knowledge. Students will reflect upon the idea that our life is a journey of discovery, and along the way we need to prepare by predicting what we will need to have and what we will need to know.
