DO NOW: Task #1 Who is this person? Study the face above. On your worksheet, write down who you think this person is and perhaps write a little bit about him/her. What nationality? What age? Why is the image so grainy? You have 2 minutes to jot down some thoughts, things you wonder, or things you notice.
What you will be expected to accomplish by the end of today’s lesson: Identify some issues that are present in 2013. Predict if life be the same in 2113? Think about what might change in your future. Do you have any control over that decision?
Vocabulary to know! Population: the total number of people in an area. Population Distribution: the way the population is spread out over an area. Demography: the science that studies population distribution and change. Population Density: the average number of people per square mile or square kilometer. Birth Rate: the number of live births each year per 1,000 people. Death Rate: the number of deaths each year per 1,000 people.
Task #2 Watch the You Tube videos “7 Billion” and “Are you typical?” and write down as many facts as possible on the face worksheet from task #1. Be ready to discuss them with your partner.
Time to Think, Reflect, and then Chat! Now you need to spend the next few minutes looking over your notes from the video. Take 2 minutes to add anything you may have forgotten to write down. TIME! Now, you may turn-pair-share with your partner to discuss your findings. Who is the person in the photo?
What does population growth depend on? * Birth rare and death rate What are birth rate and death rate? *Birthrate is the number of live births each year per 1,000 people; death rate is the number of deaths each year per 1,000 people
Reasons for Population Growth Today Birth rates increased, death rates decreased Why?? 1. New farming methods increased the world’s food supply. ***Improved important food crops and found new ways to protect crops against insects ***Ability to raise crops with less water. ***These reasons all led to the improvements in agriculture called the Green Revolution. 2. Health and medicine ***Clean drinking water and sanitary waste removal ***Vaccines ***Antibiotics
In the past, as societies became more prosperous there was an increase in levels of sanitation, nutrition and health care which led to a decrease in the death rate.
Most of the population growth over the next several decades is expected to occur in developing countries, where growth rates are generally higher than for developed countries (1.5 to 2.1 % vs 0.2% for the most affluent countries). The United States is an exception, with one of the most rapidly growing populations of any developed nation.

Task #3 Discuss some issues that are present in 2013. List at least 3. Will life be the same in 2113? Why do you think it will or will not be the same? Give at least 2 examples of your thinking. What might change? If this is not done in class, it will be completed for homework.
What is Population Density? Population density is the average number of people per square mile or kilometer. Population density is normally worked out using the following formula: Total Population / Total Land Area = Total Population Per Square KM. Densely populated areas are where many people live and sparsely populated areas are where few people live.
Look at those Pictures! Task: Choose two of the images that show areas of the world that have low population densities. Annotate all the reasons why these areas are sparsely populated. Where in the world do you think your photo was taken? Add a feature e.g. desert, and location e.g. the Sahara. How do you think Physical Factors affect Population Distribution?
Why are some places crowded & others empty? Examine the photo. What do you notice? What do you wonder? What does this culture show about the people in the picture? Do you think it is sparsely or densely populated? Why?

Rural v.s. Urban If you live in the countryside, you live in a RURAL area. If you live in a city or town, you live in an URBAN area. Let’s look at some examples.
Rural communities can have many farms and plenty of land in between each privately owned farm.
Not all rural areas look the same. India China USA
Not just NYC??? What is this? A megacity is usually defined as a metropolitan area with a total population in excess of ten million people.  Some definitions also set a minimum level for population density (at least 2,000 persons/square km). [ A megacity can be a single metropolitan area or two or more metropolitan areas that converge.metropolitan areapopulation population densitymetropolitan area As of 2013, there are 24 megacities in existence according to the Population Reference Bureau. The largest of these are the metropolitan areas of Tokyo, Delhi, Mexico City, New York and Shanghai: each of these has a population excess of 20 million inhabitants.  Tokyo is the largest metropolitan area, while Shanghai is the largest city proper.Population Reference BureauTokyoDelhiMexico City New YorkShanghai largest metropolitan arealargest city proper
