Students gain knowledge of local history, their natural environment, native cultures, and community planning.



The class works collaboratively to design and construct a three-dimensional model of a pre-history environment. (In subsequent sessions, the class considers social, historical, and environmental issues as they transition their model from an uninhabited natural habitat to a modern urban community.)



This project-based curriculum represents an extended unit. It works well as a two month unit, with the class spending time each week, for one month, learning about history, watersheds, bridges, native cultures, etc. The actual model can be built over approximately three weeks if the students work one hour per day.

Alternatively, the project could be a year long experience, or condensed into a "living laboratory" intense 1 - 2 week experience.



· 3 sheets of large bulletin board paper for base of model with a recommended area approximately 6 feet by 8 feet, OR- 8 feet by 10 feet.
(other options include large sheets of cardboard from appliance boxes or butcher paper sheets.)
Choose a color appropriate for your local geography.
· several ; sheets of blue paper for rivers, lakes, streams, or other bodies of water
· brown or gray paper for mountains and other land forms
· 20 - 30 pieces of 4 inch by 6 inch, OR- 9 inch by 11 inch paper to cover flat land areas
· scrap paper in assorted colors for animals, flowers, meadows, etc.
· green paper for trees
· tape or glue
· index cards
· string
OPTIONAL:
· colored clay or other materials for optional multimedia models, especially for older student groups



1. For younger groups (approximately grades 3 - 5) it is helpful to lay out the base for the model in advance. The recommended approximate area is 6 feet by 8 feet, OR- 8 feet by 10 feet.

2. For younger students (approximately grades 3 - 5), the teacher can create and photocopy a grid template for the students to use when making a map of the model. The grid should have five evenly spaced lines in the long direction (labeled "1" through "5"), and four evenly spaced lines in the short direction (labeled "A" through "D".)



Before human civilization, environments were formed and impacted by natural phenomena. This project begins with a study of the underlying natural environment. Ask the following questions to help students imagine what the land looked like before people. (Pre-history)

What do you think our area was like before there were any people?

Let the class brainstorm. Brainstorming is a shared process that validates multiple ideas. There is no right or wrong answer here.

We are going to build our own "land before time". What landforms, water, or other significant features would you like to include in our scene?

Let the class brainstorm again. Make a list of the specific suggestions.

What animals are here and what do they need?

Let the class brainstorm again.

Then categorize, prompting students to recognize any important aspects not covered.



Select student teams to work together to construct natural features on the project model.

Working as a class, or in student teams, plan the natural environment for the model. Take the following into consideration:

1. Is there a body of water in the environment? Is there a river flowing into the ocean? Is there a lake, pond, marsh or swamp? Where will it be located?

2. What geographical features will be in the model? Are there mountains, hills, valleys, canyons, plateaus, rocky areas, or beaches? Where will they be located?

3. What environmental features will be in the model? Are there forests, woods, fields, or meadows? Where will they be located?

4. Draw and label the plan.



1. Set a base for the model in a location where students can reach it. It is easiest if the model can be set in a permanent location for the duration of the project.

2. Add paper representations of major geographical and environmental features. (Optional: You may choose a wider variety of media, such as clay, recycled objects, etc.)

- Add significant landforms (brown or gray paper), such as hills and mountains and secure them to the base with tape or glue.

- Add bodies of water (blue paper) appropriate to your area, such as rivers and streams, and secure them to the base with tape or glue. Note: streams and rivers flow off the mountains.

3. On smaller sheets of paper, groups or individuals create environmental 'background'. In the Pacific Northwest, background will be forested areas filled with trees or meadows, and wetlands. These pieces can be placed on the scene after the major landforms and water are down and secured. Having each student or pair create a part of the background is easiest if they have a small piece of similarly colored paper on which to glue trees, etc. (e.g., a 9 inch by 12 inch sheet of construction paper).

4. Lay down the grid for mapping using lengths of string. Label the spaces with index cards, using five sections for the length (labeled "1" through "5") and four sections for the width (labeled "A" through "D"). (For younger groups it works best for the teacher to work with several students on this.

5. Using a photocopy of the grid with numbers "1" through "5" and letters "A" through "D", each student creates a map of the natural features. (For younger students, the teacher can create and photocopy a grid template for the students to use.)

Class decides on symbols for map legend and students fill in own map accordingly. A transparency is helpful so the teacher can model-starting with major landforms, then adding water bodies, swamps, etc.

6. Summarize the environment.



Discuss placement of land and water forms. Practice talking about the location of specific landforms using the map coordinates.
For example, ask:
Where is the swamp located on the grid?
What would you find in A, 5 on the grid?



The following are suggestions to extend the project into various curricular areas. These can be done as a class, by student teams, or by individual students

Environmental Biology
Define 'biome' and 'ecosystem.' Describe features of a local ecosystem, including climate, geological features, animal and plant life.

Explore dynamic nature. Have them write a descriptive piece answering the question: How does nature change?

Define "watershed". To explore watersheds, and the question "Where does water flow?" try the optional activity Crumple Your Own Watershed.

Social Studies
Develop a timeline for your local area. When do people first arrive?

Geography
Spend time studying maps and making the student maps.

Math

Mapping - relate the mapping grid to graphing. Explore the X and Y axes with the students. Use a legend to explore symbolic representation. Practice locating objects on the grid.

Scale - Older students may utilize scale as they build.

Measuring and constructing.

Art
Visual depiction of natural objects.
Adjust to aerial view.
Use of color, shape, details and symbols to convey the larger scene.

Reading
Read legends of how the earth formed, etc.
Read nonfiction about the natural area.
Read poetry about the natural world.

Writing
Write descriptive pieces of the environment or the ecosystem of the model. List and categorize brainstorming and planning ideas. Write out pre-plan for model.
Write a project summary.
Write poetry about the natural world.

Communicating
Brainstorming and planning involves listening and tracking ideas, speaking with pauses for the next idea, group discussion, building on others' ideas, evaluating and prioritizing without negative judgment, articulating concerns;
listening to everyone.

Planning involves building on best ideas together and reaching consensus, or at least a way to move forward.

Biome - All plants, animals, and other organisms that make up a distinct natural community in any climatic region. The ocean is an example of an aquatic biome, examples of terrestrial biomes include tundra, temperate forest, and grassland.

Ecosystem - The interacting system that encompasses a community of organisms and the nonliving physical environment.

Dynamic - Active, always changing.

Watershed - The whole region or area contributing to the water supply of a river of lake.
