Presentation Transcript

  1. Thurs. 9/5/13 • Bellringer – Types of Growth • Notes: Linear vs. Exponential HAULT Types of Graphs • Start World Population Graphs

  2. Thurs. 9/5/13 • Bellringer – Types of Growth • Notes: Linear vs. Exponential HAULT Types of Graphs • Start World Population Graphs • HW: World Population Graphs

  3. $ Types of Growth $ • You just got a new job working at the Lincoln Park Zoo. The job is temporary, only for the three weeks. • Your boss gives you two options of how to be paid, which do you choose?

  4. Option 1: He will give you $50 for the first day of work, and increase your salary by $50 each day for the whole 3 weeks. Example: $50, $100, $150, $200 • Option 2: He will give you one dime for the first day of work and double it each day for the whole 3 weeks. Example: $0.10, $0.20, $0.40, $0.80 • Explain which pay scale you will pick and why?

  6. Exponential Growth • Exponential growth – occurs in proportion to the current total

  7. Linear Growth • Linear growth – Growth continues at the same rate, regardless of the population

  8. Logistic growth – occurs when (exponential) growth is slowed by limiting factors Populations can grow exponentially, but growth is usually limited by resources

  9. Carrying capacity – The number of individuals that a particular environment can support • Birth rate = death rate • Population size is stable

  10. The Limits to Growth (CARRYING CAPACITY)

  11. Comparison:Exponential vs. Logistic Exponential growth Carrying capacity Logistic growth

  12. Types of Graphs • 3 Very common types of graphs… but when do we use them??

  13. . . . a Bar Graph. Bar graphs are used to compare things between different groups or categories.

  14. . . . a Line graph. • Line graphs are used to track changes over short and long periods of time. • Line graphs can also be used to compare changes over the same period of time for more than one group.

  15. Different Kinds: Line Graphs • Line Graph: Shows how the value of something changes over time • Examples: • Plant growth over time • Amount of swears per conversation

  16. . . . a Pie Chart. • Pie charts are best to use when you are trying to compare parts of a whole (or percentages). They do not show changes over time.

  17. Different Kinds: Pie Charts • Pie Chart: Shows how much each part is of a whole • Examples: • Hours spent a day doing an activity • How much is/is not Pac Man

  18. H.A.U.L.T. • H – Header • A – Axis Label • U – Units • L – Legend • T - Trend

  19. Fill in the Blanks • H ______________ • A ______________ • U ______________ • L ______________ • T ______________

  20. Lynx and Hare Populations 1850-1950 ______________

  21. Time to Graph World Population!! • This population graph shows CHANGE OVER TIME… What type of graph will it be?

  22. 9/6/13 5th/6th • Bellringer: HAULT • World Population Growth Video • Complete Population Graph (Packet) • Family Demographic Data (HW)

  23. 9/6/13 4th • Bellringer: H.A.U.L.T. • World Population Growth Video • Human Population Graph Packet… (Set up Graph Axis Correctly!!!) • Complete Packet • Family Demographic Data (HW)

  24. Set up your bellringer like this… H ______________ A ______________ U ______________ L ______________ T ______________

  25. U.S.A. – Last 80 years

  26. Population Change (Outline) • I. Population Equations • II. Population Definitions • III. Stages of Demographic Transition

  27. 9/9/13 4th • Bellringer: 7 billion people • World Population Video • Finish Graphing?? • Population Notes

  28. 9/9/13 5th/6th • Bellringer: 7 billion people • Turn in Family Demographic Info & World Population Graph/Reading • Population Growth Notes • Population Pyramids

  29. WORLD POPULATION – PAST 12,000 YEARS

  30. 7 Billion People • Most of Human history occurred with less than a billion people on earth. In the past 100 years, population has exponentially grown to over seven billion people. • What factors do you think have led to the extreme population growth over the past 100 years?

  31. 9/11/13 4th • Bellringer: Predictions • Population Growth Notes • Continue working on Family Demographic Project • Project is due Friday!

  32. Predictions Look at your predictions from yesterday. Do you appear to be right? Explain why you think so or don’t think so. (if you were absent yesterday, make predictions about our family demographic changes over the past 4 generations)

  33. Population on an island (Easier) • Change in Pop. (Δ) = Births(B) – Deaths(D) • Δ = B -D

  34. Monkey Island – Puerto Rico

  35. 2010 Population Change • In 2010, 33 monkeys were born and 29 monkeys died • Δ = B -D • Δ = 33-29 • Δ = + 4

  36. 2009 Population Change • In 2009, when a tropical storm hit Monkey Island, 29 monkeys were born and 108 monkeys died. • What was the change in population? • Births (29) – Deaths (108) = -79

  37. Population Change Mainland(Harder) • Change in Pop. (Δ) = (Births + Immigration) – (Deaths + Emigration) Δ = (B + I) – (D + E)

  38. Canada Geese populations in Chicago

  39. Figure 53.3 Births Deaths Deaths and emigrationremove individualsfrom a population. Births and immigrationadd individuals toa population. Immigration Emigration

  40. Canada Geese near the North Pond (2010) • 38 geese were born • 29 geese died • 60 immigrated (came to North Pond) • 45 emigrated (left North Pond) • Δ = (B + I) – (D + E) • Δ = (38 +60) – (29 + 45) • Δ = +24

  41. Canada Geese in Chicago (2010) • 700 geese were born • 550 geese died • 210 immigrated (came to Chicago) • 140 emigrated (left Chicago.) • Δ = (B + I) – (D + E) • (700 + 210) – (550 + 140) =

  42. 9/12/13 4th • Bellringer: LPHS Population Change • Continue Population Growth Notes • Family demographic PROJECT Due Tomorrow! • Field Trip form & $5 due tomorrow

  43. LPHS Population Change • Δ = (B + I) – (D + E) • 500 freshman entered the school (born) • 400 seniors graduated (died) • 100 students transferred in (immigrated) • 50 students transferred out (emigrated) What is the population change of LPHS? (SHOW YOUR WORK!!!)

  44. Fertility Rate (Birth Rate) Estimate of the average number of children a woman will have during childbearing years 3.1 children in developing countries 1.6 Children in developed countries
