Environmental Science Do Now November 1, 2017
1) Which stage of the demographic transition model would represent when a place is first colonized? Why? 2) Which stage of the demographic transition model would represent a country like Mexico? Why? 3) Which stage of the demographic transition model would represent a country like England? Why? 4) Explain the thin section of the graph that represents stage 5. What’s happening to the population with respect to the birth and death rates?

Environmental Science Do Now November 1, 2017
1) Stage 1 because the population is low due the fluctuations in the birth and death rates. 2) Stage 2 because Mexico’s population increases based on a stable birthrate and a declining death rate. 3) Stage 3 because England’s population is rising slowly based on its birthrate and death rate stabilizing. 4) In stage 5, the population is beginning to decline as the death rate becomes slightly greater than the birthrate.

1st Quarter ends on Thursday, November 9, 2017 (4 school days)
Reminders Parent-teacher conferences and PD for staff (schools closed for students) on next Monday, November 6, 2017 1st Quarter ends on Thursday, November 9, 2017 (4 school days)

Objective The student will demonstrate the ability to explain the growth of populations and various factors, such as, the social impact of an aging population and technology; by performing a close read and analyzing population curves, to make connections and draw conclusions. Mastery Level: 30 points of annotation comments + 6 annotation symbols on a close read article (social impact of an aging population/technology), 4/6 TDQs answered

6
Homework – Copy! Suppose the world’s life expectancy increased by 20% for males and females. Give three problems this may pose to our current strained resources.
7
Engage Students will watch a YouTube video called “HOW AN AGEING POPULATION WILL CHANGE THE WORLD - BBC NEWS”. Guide Question: Why are demographic experts concerned with our aging population? Source:

Explore Students will perform a close read on the article titled “The Psychological and Social Impacts of Aging”. As the students read the article, they will annotate it using the symbols posted in the classroom. Students will also write textual comments in the margins of the article. Students will answer 5 text-dependent questions that are based on the article. Students will work in groups of 3 to discuss their sections of the article and will record their responses to the text-dependent questions with each other. Source:

Explore – TDQs on Aging Article
1) What is the main idea of the article? 2) Cite 3 statements from the article to support your main idea. 3) What is the author’s purpose for writing this article: entertainment, information or persuasion? How do you know? 4) How is the text organized to help build your understanding of the main idea? 5) Now that you have read the article, explain what the author failed to discuss about aging or the elderly? Explain why this topic should have been discussed in the article. Where should this topic have been mentioned in the article? Why?

Recent Trends in Human Population Growth – Copy!
Lesson 8.1 Trends in Human Population Growth Recent Trends in Human Population Growth – Copy! Growth rate of human population has slowed from 2.1% to about 1.2% since the 1960s. Population growth rates vary by region. Some nations have negative population growth rates, meaning the population is getting smaller. Humans use technology to extend Earth’s carrying capacity for our species. Did You Know? To estimate how long it would take any population to double, divide 70 by its growth rate.

Lesson 8.2 Predicting Population Growth
Age Structure – Copy! Age structure describes the relative number of people within different age brackets in a population. A population of mostly young people tends to grow. A population of mostly old people tends to shrink. A population with equal numbers of young and old tends to remain stable in size.
13
Sex Ratio – Copy! Describes the relative numbers of females and males
Lesson 8.2 Predicting Population Growth Sex Ratio – Copy! Describes the relative numbers of females and males Typical sex ratio for humans is 1.00 females : 1.06 males. For every 100 females born, 106 males are born. Human activity such as migration can skew sex ratios.
14
Environmental Impacts – Copy!
Lesson 8.3 People and Their Environments Environmental Impacts – Copy! The environmental impact of humans depends on the way they live. Poorer societies tend to have smaller ecological footprints than affluent societies, but still strain the environment: Overwhelmed governments can’t supply clean water or adequate sewage treatment. Poverty often leads to land overuse. Deforestation, flooding, disease, and habitat loss can become common, as land is cleared for farming.
15
Lesson 8.3 People and Their Environments
The Wealth Gap – Copy! Currently, the richest 20% of the world’s people use 86% of its resources. As developing nations such as China continue to develop, new environmental problems will emerge, as the need for and use of resources increases. Resource availability affects quality of life. Did You Know? Globally, 1.4 billion people live on less than $1.25 per day, and another 2.6 billion live on less than $2 per day. Burning of fossil fuels creates a haze of pollution over the eastern coast of China.
16
Impacts of Technology – Copy!
Lesson 8.3 People and Their Environments Impacts of Technology – Copy! Negative impacts: Has enabled resource exploitation (abuse) Has resulted in pollution, biodiversity loss, and climate changes Positive impacts: Enables longer, healthier, more comfortable lives Technologies such as recycling can help reduce environmental impact. Renewable energy technology can produce cheap, clean energy. Solar water pump

Extend/Evaluate – Interpreting Age-Structure Diagrams
Read “Forecasting Population Size” on page 220 and will use the information from the reading to explain figure 2 (Age Structure Diagrams). Give an example of a country with each type of age-structure diagrams. 100% SKILLS EXCEPTIONALLY MASTERED – Full explanation including example of a country for each age-structure diagram 80% SKILLS WELL MASTERED – Full explanation without an example of a country for each age-structure diagram 60% SKILLS BASICALLY MASTERED – Partial explanation with incorrect examples or without an example of a country for each age-structure diagram <60% SKILLS NOT MASTERED – Illogical explanation
