The Lewis & Clark Expedition


Social Studies American History Westward Expansion to 1850 The Lewis & Clark Expedition
Students start by making observations about an animated map of the territorial expansion of the United States until 1800. Then they learn about the Louisiana Purchase and identify two cause-effect relationships related to it. Next they analyze the Lewis and Clark expedition and Sacagawea’s role in it. Finally they research three topics and prepare short presentations on the Lewis and Clark expedition: the places they visited, the flora and fauna they documented, or the tribes that they met along the route.

This learning experience is designed for device-enabled classrooms. The teacher guides the lesson, and students use embedded resources, social media skills, and critical thinking skills to actively participate.

Overview

In this experience, students begin by making observations about an animated map showing the growth of U.S. land claims through 1800. Then they learn about the Louisiana Purchase and identify cause-and-effect relationships connected to it. Next, they read about the Corps of Discovery and Sacagawea’s contributions to the expedition. Finally, they research and prepare a short presentation about places along the expedition’s route, plants and animals recorded during the journey, or Indigenous tribes and individuals the Corps encountered.

Students collaborate in small groups for Scene 4. Each group divides three research tasks among its members.

If you have access to leveled readers that include stories about the Lewis & Clark expedition or Sacagawea, assign them to the students in parallel to this experience.

Estimated duration: 50-90 minutes, depending on how much time you want to give the groups for the research and short presentations in scene 4.

Engage


George Washington served two terms as President and helped establish the new federal government. John Adams became the second President and served one term. In the election of 1800, Thomas Jefferson defeated Adams and became the third President of the United States. In this experience, you will learn about two important events during Jefferson’s presidency: the Louisiana Purchase and the Lewis and Clark expedition. Both events increased U.S. interest and control over lands in the West, where many Native nations already lived.

Objectives

  • Analyze the impact of the Louisiana Purchase
  • Evaluate the importance of the Lewis & Clark expedition


Click the animated map and watch to see how the United States grew between independence and Jefferson’s election in 1800.

Make an observation about the map.



If students haven’t made the following observations, prompt them with questions:

  • The western edge of U.S. territory was the Mississippi River.
  • Some states gave up territory to the federal government.
  • Not all U.S. land was organized into states.
  • After independence, there were still border disputes with Spain and Great Britain.

Ask students: What do you think U.S. leaders and settlers knew about the land west of the Mississippi River?

Explain that U.S. leaders and settlers had some information about western lands from maps, traders, trappers, and earlier European expeditions. However, their knowledge of much of the region was limited. Native nations had lived in and traveled across these lands for generations, with extensive knowledge of the land, rivers, plants, animals, and travel routes.
