Minnesota: A History of the Land is a four-part documentary series that weaves

together human and natural history and illustrates the historical and ongoing

importance of Minnesota’s landscapes to the social, cultural, and economic systems

of the region.

Throughout time, humans have altered their landscapes. In the 500 years since Europeans

arrived on this continent, the physical landscape has changed profoundly. Minnesota: A

History of the Land tells part of that story chronicling the vast changes that Minnesota’s

ecosystems have undergone, from presettlement to the present. By showing how humans

have shaped and interacted with the land, this series provides a powerful context for under-

standing the region’s current environmental challenges.

A set of powerful insights about the relationship between the physical environment and

humans binds the four episodes of the series together:

• How humans view the land determines how humans use the land. In Minnesota, for

example, different people have viewed (and thus used) these lands very differently.

Because of human perception and action, the landscape has been altered dramatically

and, in many cases, irrevocably.

• Apart from human perceptions, these lands have always had their own existence.

Landscapes are first and forever ecological entities that react to disturbances in ecologi-

cal ways—through an immense web of complex interdependencies, cycles, and energy

flows that is connected to landforms, soils, seasons, and rainfall patterns.

• The gap between human perception and ecological reality has led repeatedly to unin-

tended and often negative consequences. Because of this, people have been forced to

adjust their view of the land and thus their use of the land. This halting, adaptive

process means that the landscape shapes people even as people shape the landscape.

• In changing these landscapes, people not only replace old, complex landscapes with

new, simplified ones, they set the terms of engagement—the limits of what is possible

for future generations.

The series can be viewed in a number of ways: as social and political history, as a history of

environmental thought, as a history of technology, or even as lessons in ecology.

Goals for Student LearningThis teachers’ guide is intended to help middle-school students view the Minnesota: A History

of the Land video series and develop an understanding of the following key concepts:

• The land (physical environment) has played a powerful role in shaping Minnesota’s

economies and communities.

• Minnesotans have had an enormous impact on the state’s waters, plants, and wildlife and

have an important role to play as stewards of the environment.

• The historical causes of the landscape’s current condition—its health, use, and long-term

sustainability—are essential to understanding crucial issues of conservation and natural

resource management.

How to Use the Teachers’ GuideWhile the video alone is an effective educational tool, this curriculum is designed to help

middle-school teachers guide students to uncover the main points in each episode and to

expand the ideas described above. As you watch the video in your classroom, we suggest you

break your viewing into smaller sections. Each hour-long episode is composed of three to

four segments that range from twelve to twenty minutes in length.

I. The Episode Orientation presents a synopsis of each one-hour video as well as an easy-

to-follow guide to viewing and using each video. The orientation includes:

• a summary of each episode’s content and a time-coded abstract for each segment

• Northern Lights links, which cue users to related chapters of Northern Lights: The Story of

Minnesota’s Past, a middle-school curriculum of state history developed by the

Minnesota Historical Society

• key terms needed to understand the concepts in the video, along with brief definitions. You

may find it useful to preview these terms with your students before watching the video.

• discussion questions that explore concepts presented in each episode and require students

to synthesize information, think through implications, and draw conclusions

II. In addition, a viewing guide for each episode provides a list of questions that help students

identify the main concepts of each segment. You may find it helpful to pause the video after

each segment to allow students to discuss and revise their answers.

III. Each episode has two lessons designed to amplify the central ideas presented in that

episode. Each lesson contains a lesson plan to guide teachers in setting up and conducting

that exercise, and a reproducible worksheet on which the students’ work is done. Additional

ideas for related extension activities are included for each episode.

IV. Additional resources such as reference maps, suggested resources, and answer keys are

included to help the teacher and students.

EPISODE I: Ordering the Land / 16,000 BP–1870s

Witness 16,000 years of Minnesota’s fascinating early history.

Its unique place in North America is revealed through state-

of-the-art animations and graphics. Prominent members of

Minnesota’s Native American community describe their long

relationship with the land. With the arrival of Europeans

comes a new way of looking at the land, one that will change

the region forever. See how this is expressed in the land sur-

vey, which carves the natural world into squares that can be

bought and sold. The fur trade era and early lumbering are

brought to life with historic re-creations and photographs.

Discover what happens when early entrepreneurs fail to

understand the geology of St. Anthony Falls.

EPISODE II: Changes in the Land / 1870s–1900

Voices from the past and stunning nature videography re-

create the natural world Euro-Americans first encountered.

Find out what happens to North America’s most abundant

species as commercial hunters and the railroad arrive in

Minnesota. The majestic Big Woods are cut down to make

room for farms and villages. Visit one of the little-known

crown jewels of Minnesota, the Bluestem Prairie. Find out

why Minnesota has some of the richest soils in the world

and how Minneapolis becomes the flour-milling capital of

the world. Historic re-creations bring to life the bonanza era

of wheat farming. And experience the catastrophic fire that

ushers in a new way of looking at the land.

EPISODE III: Out of the Ashes / 1900–1940s

Never-before-seen historic footage brings to life the begin-

nings of conservation in Minnesota. Discover why

Minnesota is at the forefront of conservation in the United

States and the key role that women play. See what happens

to the Mississippi River as the population of the Twin Cities

explodes. Graphic animations help viewers imagine the

results of one man’s plan to flood the boundary waters

region. Then, get to know the fascinating character who

helps to save the region from destruction. In the series’ most

ambitious historic re-creation, find out which prominent

Minnesota conservationist begins his career promoting the

destruction of wolves.

EPISODE IV: Second Nature / 1940s and Beyond

Unique historic footage and photographs depict the

momentous changes brought to Minnesota during and after

World War II. A vivid re-creation brings to life the revolu-

tionary work of a University of Minnesota graduate student.

Simple inventions like nylon nets and the introduction of an

exotic species bring the fishery of Lake Superior to the brink

of collapse. Through rarely seen footage, experience the

extensive pollution of Lake Superior caused by the disposal

of over 60,000 tons of waste a day. Then, hear firsthand how

a group of citizens plays a central role in stopping this pollu-

tion. Discover the ways in which our own homes and busi-

nesses result in changes in the land as far away as the rain

forests of South America. Consider how the stories of

Minnesota’s past can inform our choices for the future.

SERIES OVERVIEW

Episode SummaryBefore World War II, ecology was still more art than science. In 1942, the work of a young University of Minnesota graduate stu-

dent, Ray Lindeman, jump-starts the modern field of ecology, giving people unprecedented insight into how ecosystems work. His

discoveries come at a critical time, because with the war’s end, the industrial technology that won the war begins to be used to

reshape the Minnesota landscape at an unprecedented rate and scale. At the same time, developments in ecological understanding

move some citizens to question the way we use our natural resources.

Lake Superior was home to a thriving commercial fishery. But from its beginning in the nineteenth century, sequential overfishing

of select species led to significant declines. By the early twentieth century fishermen have turned to lake trout, and harvesting accel-

erates through World War II. Trout populations reach a tipping point when a new exotic species enters the lake. The widening of the

Welland Canal opens the way for the sea lamprey, and in a matter of a few years they destroy what was left of the commercial lake

trout fishery. At the same time the purity of Lake Superior is threatened by massive dumping of taconite tailings by Reserve Mining

Company. Local concerns and citizen action result in a landmark federal court case. With the final end of dumping in the early

1980s and with the success in treating lamprey, the restoration of the fishery can begin.

But even as these events are unfolding, far greater transformations are occurring across the rest of the state. The end of World War II

brings with it a return to prosperity, which along with the new federal highway system ushers in a period of unparalleled suburban

expansion. The consequences for the landscapes of Minnesota are enormous as productive agricultural land is lost and hydrologic

systems are altered. But there are implications that reach beyond Minnesota all the way to the rain forests of South America. And the

loss of biodiversity may have unforeseen consequences for us all. These stories and those portrayed throughout the series are briefly

reviewed in the hope that lessons from the past will help us make better choices for the future.

ORIENTATIONEpisode IV: Second Nature (1940s AND BEYOND)

6.0 minutes Episode Introduction. An introduction describes thework of Raymond and Eleanor Lindeman and what theirresearch meant for the field of ecology and our under-standing of how our ecological landscapes function.

10.0 minutes Big, Bold, and Cold is the story of the collapse of LakeSuperior’s once vast fishery. A century of overfishinghad depleted populations of the lake’s top fish preda-tors, which were also the heart of the commercial fish-ery. The arrival of the sea lamprey, an exotic ocean-going fish predator, provided the final blow. With noevolved defense against the lamprey, Superior’s laketrout population collapsed.

20.0 minutes A Landmark Case tells the story of the nation’s firstmajor federal environmental pollution case. By the1960s, decades of mining had exhausted the high-gradeiron ore, when a new process came online that couldutilize the remaining low-grade iron ore. Taconite pro-

duction pumped new economic life back into the IronRange but at a cost. Reserve Mining began dumpingthe waste directly into Lake Superior, polluting the lake,and possibly endangering the health of people and fish.The action fueled a popular challenge to the company’spractice. Local and national environmental groupspressured the state and federal government into filingthe nation’s first major environmental pollution lawsuit.Eventually the company was forced to move its tailingsonto land.

4.0 minutes Restoration of Lake Superior is the story of the recov-ery of Superior’s lake trout populations. After fiftyyears of trial and error, fish stocking, and lampreycontrol, naturally reproducing lake trout are increas-ing in numbers. The rehabilitation of lake trout in LakeSuperior is one of the major successes in fisheriesmanagement worldwide. (continued)

16.0 minutes The Crabgrass Frontier chronicles the effects of abooming economy and growing population on thestate’s landscapes. Proliferating suburbs and the arrivalof the federal highway system served to accommo-date a newly affluent and growing human populationbut at a tremendous cost to the environment. Paved-over natural landscapes altered hydrological cyclesand caused widespread water-quality problems. Assuburbs and roads expanded, they also swallowed upfarmland and what remained of the state’s alreadycompromised natural lands. Biological diversity suf-fered, as those landscapes became fragmented—afact exemplified by Minnesota’s declining neotropicalbird populations. But the real challenge is the predict-ed increase of one million more people to the state’spopulation in the next decades.

3.0 minutes Unfinished Journey features reappearances by pastcommentators, who review the journey we’ve taken inthis series. It is suggested that we need to learn fromthe mistakes we’ve made—to question the assump-tions we commonly make. But it is also clear thatMinnesotans have demonstrated capacity to do theright thing. The film’s conclusion suggests that we havean obligation to future generations as the stewards ofthis “amazing” planet.

Lesson Objective Upon completion of this lesson, students will understand:

• How the origin, diversity, and rate of arrival of exotic species

have changed over the past two hundred years

• How technological developments and changes in modes of

transportation have affected the arrival of exotic species

MaterialsLesson 7 Worksheet

Background Non-native species have become a significant threat to

Minnesota’s ecosystems, including rivers, lakes, and land areas.

It is estimated that in the Great Lakes only about 10 percent of

non-native species have caused harm to agriculture, industry,

human health, or the natural environment. However, even that

number of species has caused significant environmental and

financial damage.

Almost half of the non-native species in the Great Lakes are

likely to have entered through ballast water on ships. When a

ship travels without cargo, it requires ballast or weight to pre-

vent it from bobbing too high in the water. After removing

cargo, many ships pump in water from harbors to act as bal-

last. When they reach the next port, they empty out the ballast

water and take in new cargo. This ballast water and any sedi-

ments captured in these foreign waters can carry non-native

species. When ships travel to the Great Lakes from regions that

have similar water temperatures and salinity (like the Caspian

and Black seas), there is a higher likelihood that these non-

native species can adapt and thrive in the Great Lakes environ-

ment. If the ballast water was collected in salt water or tropical

areas, the dangers of non-native species flourishing are smaller.

Since 1993, law has required that ships entering the Great Lakes

from outside U.S. or Canadian waters must exchange their bal-

LESSON 7 PLANEpisode IV: Second Nature (1940s AND BEYOND)

LESSON 7 PLAN: The Great Lakes

last water at sea. However, the effectiveness of this law is suspect.

It is difficult to gauge how many ships actually do exchange their

water. Even so, the ships that do bother to exchange their water

may still carry non-native species. After emptying ballast water,

up to 15 percent of the original water may remain in the tanks

and pipes, and a residual sludge of sediment often remains at the

bottom of the tank. Scientists are looking into the possibilities of

cleaning ballast tanks through radiation or other processes, but at

this time, such ideas are too time-consuming and expensive for

shipping companies to implement.

Procedure1. With the class, review the section Big, Bold, and Cold in

Episode IV.

2. Ask students how familiar they are with the subject of “exotic

species” or “invasive species.” Could they write a definition of

these terms? What are some animals or plants that are consid-

ered to be exotic species in Minnesota? What are some consid-

ered to be “invasive”? What might make some exotic species

harmful, and others harmless?

3. Discuss with the class the process of transporting species

through ballast water (see above).

4. Divide students into small groups, and have each group study

one aspect of the worksheet such as When Did They Come?,

Where Did They Come From?, and What Are They?

5. Ask students to create a “Live Film Strip” with their group that

explains what they have learned. In the “Live Film Strips” one

person is the narrator, and the rest of the group poses as what

the narrator describes. For example, the narrator could describe

how many invasive species are transported into the Great Lakes

in bilge water in three “scenes” or “slides.” As the narrator

explains this, the other students pose as invasive species getting

sucked into a boat, sitting in the bilge water in the bottom of a

boat, then being flushed out of the boat in the Great Lakes.

Page 14: EPISODE IV (3.9mb pdf)

Follow-Up Allow students to present their “Live Film Strips.” Possible

discussion questions include:

• How do these presentations tie together?

• What could we do to stop the transportation of exotic species

by shipping? How reasonable are those possible solutions?

LESSON 7 WORKSHEET The Great Lakes

Lake Superior is the deepest and coldest of the Great Lakes, and the farthest inland from the Atlantic Ocean.All of these factors protected Lake Superior from foreign fish and plant species that might enter from distantwaterways. Fish, plants, and organisms in the Atlantic Ocean had a hard time traveling up the St. LawrenceRiver, over the many waterfalls, and across the other Great Lakes to reach Lake Superior.

However, human changes have made the arrival of non-native species common. Now, a new non-native species

is discovered in the Great Lakes about once every seven months. Most of these plants, fish, and tiny creatures

appear to be harmless. Others cause enormous damage to the Great Lakes environment. Why is this happening?

What is going on? With your group, study one of the main aspects of invasive species in the Great Lakes, then

complete the questions in your section, and create a “Live Film Strip.”

Invasive Species: When Did They Come? How Did They Get Here?Take a look at the charts above, which show the number of invasive species that arrived in the Great Lakes by

each decade from 1830 to 2000 and by percentage. Also consider the time line of major events that occurred in

the Great Lakes, then answer the following questions.

1. What is the general pattern of the number of invasive species that are discovered each decade?

2. What connections do you see between time line events and increases in invasive species?

3. What method of release has been the most common in the past fifty years? Why might that be?

Invasive Species: Where Did They Come From?Consider this chart that shows what areas of the earth

the invasive species in the Great Lakes came from. For

invasive species to survive in the Great Lakes, they

need to have come from habitats with similar tempera-

tures, food sources, and salinity (water saltiness).

sive species in the Great Lakes? Why might that be?

5. What area of the earth has the greatest number of invasive species in the Great Lakes? Why might that be?

Invasive Species: What Are They?Take a look at this chart showing the types of invasive

species, and think about what you have learned about

how invasive species were released into the Great

Lesson Objective Upon completion of this lesson, students will understand:

• How choices in neighborhood density and design affect job

needs, transportation needs, and pollution

MaterialsLesson 8 Worksheet (hint: do not copy this back-to-back,

but use two pages)

Colored pencils

Background Today, most people are aware that urban sprawl causes signifi-

cant regional consequences. Even so, many new developments

continue to be built in a sprawling way, creating expensive low-

density housing and dispersed business and industrial zones,

greater freeway traffic, and a decrease in natural areas. However,

few people are aware that smart growth or planned growth can

create neighborhoods that are attractive, safe, and better for our

communities and our surroundings. This lesson helps expose

students to some of the choices considered to be “smart growth.”

Note that we did not attempt to consider the costs of these hypo-

thetical decisions. The Internet sites listed in the “Extension

Ideas” section are particularly valuable if students want to evalu-

ate in more detail the financial implications of their choices.

Procedure1. With the class, review the section Crabgrass Frontier in

Episode IV.

2. Ask students to spend 10 minutes drawing a map that shows

the plan for the development of a city, suburb, and nearby

rural community. Ask them to include transportation corri-

dors, housing types, business zones, and native plant and ani-

mal habitat. If they are unfamiliar with one or more of these

categories, that is okay. Students will have an opportunity to

explore these categories in the following exercise. After 10

minutes, ask the students to share their drawings, and create a

master list of the characteristics associated with each of the

development types.

3. Discuss with the class why people like living in the suburbs,

city or rural community. What are the benefits? What are the

drawbacks?

4. If you have time, have students explore the Internet sites sug-

gested in “Extension Ideas.”

5. Summarize the steps that students will need to take to com-

plete this activity. If you have time, model going through the

decision-making process yourself.

6. Divide students into small groups. (This activity works well as

an individual activity or as homework, too.) Ask students to

go through the worksheet carefully and choose how to develop

their area. Students may need assistance understanding how to

color in the map key and the map.

7. When students are done, see who created the highest density,

the lowest density, the most jobs, the fewest jobs, the worst

pollution score, and the best pollution score.

Extension Ideas:

• The average two-car family takes ten car trips a day. Ask yourstudents to keep a week-long diary of how many transporta-tion trips they take. Have them note what type of transporta-tion they used (bus, car, train), how far they traveled, and howmuch time it took. At the end of the week, compile the stu-dents’ information and have them estimate the consequencesof their classroom’s transportation needs: consider gas used,pollution created, and time used.

• National Geographic has an online activity that allows stu-dents to compare sprawl and new urbanism. Go tohttp://www.nationalgeographic.com/earthpulse/sprawl/index_flash.html

• The Sierra Club has a series of “before and after” imagesshowing what the development of smart growth could looklike in typical communities. Go tohttp://www.sierraclub.org/sprawl/community/transformations/index.asp

• Internet lessons that support the Minnesota GeographyStandard: Cities and Urbanization athttp://mage.geog.macalester.edu/mngeog/CitiesInetLessons/citiesInetLessons.html

Follow-Up Ask students how they scored on their land development.

• Why did you make the choices that you did?

• How does the density of housing affect job needs?

• How does the density of housing affect transportation needs?

• How does the density of housing affect pollution?

• How could we make this simulation more realistic?

What other factors could we consider?

Name: __________________________________________ Date: ______________ Class :_______________________

Imagine that you are a land developer who has boughta 36-acre old farm on the edge of the suburbs. Youneed to choose how you will develop that land. If youaren’t careful, you could end up with sprawl: areaswith little natural land, population densities of sevento twelve people per acre, jobs that require lots of cartravel, and lots of pollution. With care, you can devel-op a smart growth area: plenty of natural land, popu-lation densities of over twelve people per acre, jobsthat don’t require too much car travel, and decreasedpollution.

Consider each of these steps carefully. In the end, rate

your choices, and see how well you did. Remember to

use colored pencils, so you can change your mind and

erase things!

Step 1. Choose what types of homes and businesses to build.

HOMESFirst, color in the key below and the map above to show which types of homes you will build, and where you will build

them. Make sure you reserve some areas for developing businesses and—if you want—creating parks. After that, com-

plete the chart to show how many acres of each type of home you will develop, and how many people live there.

Smart Growth or Urban Sprawl: LESSON 8 WORKSHEET continued

BUSINESSESColor in the key below and the map above to show which types of businesses you will build, and where you will

build them. After that, complete the chart to show how many acres of each type of business you will develop, and

how many jobs there will be.

Step 2. Evaluate the density and job base of your development plan.

How is your density? Take your total number of people, and divide by 36. If you got

< 7 people per acre: Fine choice. You decided to not develop your land very much.

7 to 12 people per acre: Uh-oh. You created a sprawling development.

> 12 people per acre: Good job! You built an efficient, smart-growth density!

How is your job base? Take the total number of people you have, and divide by the total number of jobs you

have. If you got

0.1 to 1: Fantastic! You created a smart-growth job base!

1.1 to 2: Pretty good! Many people will be able to work near their homes.

2 to 4: So-so. Some people can work locally, but more will have to travel.

> 4 : Uh-oh. Almost everyone will have to travel far for jobs.

Smart Growth or Urban Sprawl: LESSON 8 WORKSHEET continued

Step 3. Choose what types of transportation to develop.

(Using the same map, place transportation symbols over the same squares where homes, businesses, and parks have

been located in Step 1).

If you have more people than jobs, you will need to create transportation systems to get them to jobs located

elsewhere. Choose which transportation solutions you will use, locate them on your map, and analyze the pollu-

tion consequences of your choices.

Step 4. Evaluate the pollution consequences of your planned transportation network.

What were your pollution consequences? Add up your pollution consequences. If you got

< -1000: Yikes! The land has changed dramatically, and the people are causing a lot of pollution.

-1000 to -1: Well, you made some efforts to consider the environment.

> 0: Hooray! You built a development that protects the environment!

How do you compare? Ask your fellow students how they did. What were the highest and the lowest numbers in

the class? What kinds of strategies or decisions helped make the most environmentally friendly development?

Can you alter your development to improve things?
