Unit 1 -Lesson 5

Population Patterns of the Eastern Hemisphere


Big Ideas of the Lesson

Population distribution is the way people are spread out over an area.

Population density is the average number of people living in a square mile or kilometer

Settlement patterns can be studied through a variety of maps The Sahel is a semi-arid region in Africa between the Sahara on

the north and the savannah in the south Settlement patterns are linked to physical features of the Earth

as well as human features


Learning Targets: 1. I can conclude that population distribution is the way

people are spread out over an area. 2. I can estimate that population density is the average

number of people living in a square mile or kilometer.

3. I can predict that settlement patterns can be studied through a variety of maps.

4. I can explain that the Sahel is a semi-arid region in Africa between the Sahara on the north and the savannah in the south.

5. I can describe settlement patterns which are linked to physical features of the Earth as well as human features.

Population Patterns of the Eastern Hemisphere # 1

1. Guide the students to understand the difference between these two terms by a simple analysis of their school’s population.

2. Obtain a floor plan of your school building or alternately draw a sketch of the building.

3. Place the map on a document camera to project on the wall or draw an enlarged map.

4. Tell the students the enrollment (population) of the school. 5. Have them count the number of classrooms and divide that number into

the total number of students in the school. 6. Write the term “Population Density” on the school map and the average

number of students per classroom. 7. Next write the number of students in each classroom at that particular

time. Perhaps a few classrooms will be empty or have a small group of students.

8. Label the school floor plan “Population Distribution”. 9. Discuss with the students the difference and ask them for ideas when

each of the two different population counts would be useful. 10. Hang the map in the room to reinforce this information.

Population Patterns of the Eastern Hemisphere # 1 • Population density is the average number of

people living in a square mile or other measurement for area such as a kilometer.

• Population distribution is the way people are spread out over an area.

• This would show where there are areas of few people and other places that are very crowded.

School Map Activity Instructions 1. Wisely choose a partner 2. Get ONE MAP per partnership 3. Write both names and hour at the top right of the map 4. Count the number of classrooms 5. Divide the total number of students in the school (606) by

the number of classrooms (You will get an average) 6. Write the term “Population Density” (606 is the student

population in the school) on the school map and the average number of students per classroom.

7. Write the number of students in each classroom at a particular time. Perhaps a few classrooms will be empty or have a small group of students.

8. Label the school floor plan “Population Distribution” (“The students are distributed around the school”)

9. Partnership Think/Pair/Share

is 606 Students POPULATION DENSITY

POPULATION DISTRIBUTION is the number of students in classes


AFRICA


• Review physical features and how these features are related to human characteristics.

• Project an outline map of Africa or Asia on the board and give students a copy of the map you use. Copies of each map are located in the Supplemental Materials (Unit 1, Lesson 5).

• In the case of Africa, as a class have them locate, draw, and label the major physical features of Africa such as the Nile River, the Sahara, the Atlas Mountains, the Congo River, the Kalahari Desert, the Niger River, Lake Victoria etc.

• The students may use their textbooks and atlases to complete this step.


Locate, draw, and label the major physical features of Africa:

1. The Nile River 2. The Sahara 3. The Atlas Mountains 4. The Congo River 5. The Kalahari Desert 6. The Niger River 7. Lake Victoria 8. Choose 3 other features

(your choice) Add them to the list

USE ATLAS


• Human Characteristics: Ideas such as languages, religions, foods and clothing are just a few suggestions.

• Physical features are features of the earth that are not human made.

• Remember that climate is another physical feature that must be considered.

• Ask questions to guide the discussion such as, – “Where do you think few people would choose to

live?” – “Where will there be the highest population

distribution?” – “What other factors influence where people live?”


• Once the students have discussed what they think might be the population patterns of Africa, have them study the “Population Patterns in Africa” distribution map located in the Supplemental Materials (Unit 1, Lesson 5).

• Such maps can also be found in textbooks and atlases.

• The students further discuss the predictions made in Step 2.

• They compare historical maps of an area such as the Nile River Valley with modern maps of the same area.

Population Patterns of the Eastern Hemisphere - Mesopotamia









Modern Maps of Mesopotamia and

Modern Maps of Mesopotamia and Elevation of the Nile


There are two Early Civilization maps in the Supplemental Materials (Unit 1 Lesson 5). • Determine what the connection is between the

settlement patterns shown on each map. Note that the first major settlements were in river valleys.

–These river valleys had a warm climate, an abundant source of water, fertile soil and food in the form of fish.

Do you think physical features are the only factors influencing settlement patterns? Answer in SS Notebook.


• Human features have to be considered as well. • Next look at a region of low population such as the Sahel

and discuss why there are so few people who live there. – The Sahel is a narrow band of semi-arid land south of the

Sahara that gives way to the savannas, the broad grasslands in the tropical region.

– The Sahel was formerly home to large populations of grazing mammals, but over-hunting and competition from livestock has caused the endangerment and even extinction of some of the native animals.

– Other threats to the Sahel include periods of extreme drought and encroaching desertification.

How do physical factors such as those found in the Sahel affect settlement patterns? Answer in SS notebook.

Population Patterns of the

Eastern Hemisphere

(AFRICA)


• Continuing to use the outline map of Africa and reference materials, the students color or mark in the areas of highest or densest population on this continent.

• They might also refer to the “Population Patterns in Africa” map found in the Supplemental Materials (Unit 1, Lesson 5).

What might the consequences might be for a country that has a large population and a high population density in terms of stress on the environment, such as intensive farming and the resulting effects of drought or desertification on the natural environment arising from the land use practices of the people? ANSWER IN YOUR SS NOTEBOOK? • They can refer back to their discussion of the Sahel and then research other areas

of the Eastern Hemisphere that are experiencing environmental stress. • Example might include the earthquake zone in Pakistan or the flood plains of

Bangladesh.

Population Patterns of the Eastern Hemisphere ASIA


As a final check, on the board, write the question-

“Why do people live where they do?”

1. List as many reasons as you can in your social studies notebook.

2. Think / Pair/ Share

3. Students list their ideas under the question on the board

4. SUMMARIZE what they have learned in your SS Notebook

Population Patterns of the Eastern Hemisphere # 5 1st hour


Population Patterns of the Eastern Hemisphere # 5 2nd hour


Population Patterns of the Eastern Hemisphere # 5 3rd hour


Population Patterns of the Eastern Hemisphere # 5 4th hour


Population Patterns of the Eastern Hemisphere # 5 6th hour



Assessment

• The final discussion about why people live where they do will provide evidence of students’ understanding of the relationship between environment and patterns of settlement in the Eastern Hemisphere.

• Look in responses on the board and listen during students’ conversations for reasoning that includes the impact of physical features (including climate), references to population density, and how population patterns are related to the lives of the people in the region.
