Grade 8 History Students analyze the divergent paths of the American people from 1800 to the mid-1800s and the challenges they faced, with the emphasis on the West, in terms of the purpose, challenges and economic incentives associated with westward expansion including the concept of Manifest Destiny (e.g. Lewis and Clark expedition, accounts of the removal of Indians and the Cherokees Trail of Tears, settlement of the Great Plains) and the territorial acquisitions that spanned numerous decades.Opening Activity: What was it like before the United States?
I. Using Maps to Understand Change
A. What can we learn from maps?
B. Understanding Maps: Relief maps, political, outline, biomes, climate, population, sat 9 images
C. Following in the footstep of Lewis and Clark: The Voyage of Discovery
Part I. Culminating Activity: Determining a trail from Santa Fe to Los Angeles.
II. Ecosystems
A. Ecosystems: What are the components of an ecosystem
B. Ecosystems: Along the Lewis and Clark Trail
C. Ecosystems: Then and Now
D. Endangered Species: Then and Now
Part II Culminating Activity: Expository presentation that is an analysis of one species as an indicator of changes in an ecosystem from 1803 to 2003
Purpose or Objective:
Students will be able to read and understand a variety of maps.
Students will be able to analyze and interpret a variety of maps.
Students will be able to utilize information from maps to plan a route from Santa Fe, New Mexico to Los Angeles (similar to the Old Spanish Trail)Materials, Tools, and Resources Needed:
For Journal of Discovery
Each student needs:
Spiral ring notebook
Glue stick
Tape
Scissors
Colored pencils
Pens and pencil
Letter from Thomas Jefferson to Clark on his mission statementPrerequisite Student Knowledge:
Journal Writing:
Students are to glue in the daily entry from Clarks journal. They are to locate that point on their maps. Using their maps and the Internet write their journal what it is like at the location today.
Formal Letter Writing:
Letter to President Bush
Informal Letter: Postcard to teacher from one of their campsites.Procedure:
1. Using Maps to Understand ChangeStudent Activity:
Opening Activity:
Using images, original documents, and contextual prompts, students will discuss what they think the United States was like before it was developed by Europeans cultures. Starting a Journal: Journal of Discovery
Letters from Thomas Jefferson to Meriwether Lewis
Journal Entries

What was North America like before it was the United States?
Journal of Discovery
1. Students will make their Journal of Discovery (Interactive notebooks) using a three-ring notebook.
2. Discussion on the Louisiana Purchase and North America.
3. First entry in journal: Students will glue in Thomas Jeffersons letter and on the facing page write what they believe Lewis and Clark will find as they explore North America from the Missouri River.
4. Students will complete a KWL diagram on Lewis and Clark.
5. Each day students will place a passage from Lewis journal, mark the location on their map, and write a short reflection on what they learned in class today.
Activity A:
What can we learn from maps?
1. Introduction: What can we learn from maps. Show the students different types of maps. Make a concept map of what students believe they can learn from these types of maps.
2. Venn Diagram: Give each student an outline map and a satellite map of California. Have students compare and contrast what they can learn from each type of map.
3. Give each student a satellite map of the United States and a transparency paper. They are to make an outline map of the United States.
4. Go over the parts of a map, the map key or legend, the compass rose, longitude and latitude. Students are to put these items on their maps.
5. Students will then add and label the major water features.
6. Students are to reread the Letter to Clark from Thomas Jefferson and locate the Missouri River. Students are to form a hypothesis on what they will find on their journey.
7. Students are to read the first entries on the beginning of the expedition.Activity B: Understanding Maps
1. Students are to locate St. Louis on their maps.
2. Using their satellite image, students are add physical features such as the Rocky Mountains and Appalachian mountains to their maps.
3. Give students a copy of a topographic map showing the front of the Rocky mountains.
4. Students will learn to read a topographic map and choose the best route for crossing into the mountains.
5. Students are to write a formal letter to Thomas Jefferson explaining how they are planning on crossing the Rocky to the Pacific Ocean.
6. Students are to mark their route on their mapActivity C:
Lesson Performance Task:
Following in the Steps of Lewis and Clark
1. Students are to mark in Lewis and Clarks trail on their maps.
2. Students are to compare their trail with the actual trail.
3. Students are to determine if they have determined a better route for going from St. Louis to the Pacific Ocean.
4. Students are to mark 4 locations (camp sites) on their route and write for journal entries that tell what they will observe at each location
5. Students are to write a formal letter to the current president explaining why their route is an improvement over the one taken by Lewis and Clark 200 years ago. Students are to use logic and give evidence for their route selection.
6. Students will write an informal letter (postcard) from one of their campsites on their route.Part I Unit Culminating Assessment
Student will prepare a map from showing a route from Santa Fe, New Mexico to Los Angeles, CA. Using Clarks journal as a model, students will be able to use their map to develop a hypothetical journal detailing what they will find during a journey following their route. Student journal will include information on topography and natural features, climate, biomes (plants and animals).Culminating Activity/Assessment:
How does an idea about a place change when it goes from the unknown to the known?What was the importance or role of the Lewis and Clark expedition in the concept of the United Stated (manifest destiny)?
How can we use maps to know, visualize and understand a place we have never been visited?
How can maps teach use about change over time?
How can maps teach us geology, life science, and history when maps are only images with very little explanations?
Why is it important to be able to learn how to use maps?
