1. Catalyst 8/26/2011 Take out your CORE Case Study and put it in the middle of the table 1) What is a population? How would you define population in your own words? 2) Why is it important to study population and how it works? HW: 1) Finish Frayer Vocabulary Words for today’s vocabulary words 2) Summarize Cornell Notes taken in class

2. Agenda 8/26/2011 Catalyst (10 mins) Finish going over the Case Study: 10 mins Seal Watching: 10 mins Exploring our inner population ecologist: 25 mins Notes and Vocab Model: 20 mins Elaborating Your Species: 30 mins Exit Slip: 13 mins Push/Praise: 2 mins

3. Seal Watching 1)Why would the population ecologist want to gather so much data? 2)Why is the population ecologist’s job so important to not only the seals, but the environment around them? 3)Was this job fun or boring looking?

4. Building your hat 1)Fold your paper in half, hamburger style 2)Fold the corners to make two triangles 3)Fold the outer flaps of the paper up 4)Open the hat

5. Exploring Our Inner Pop. Ecologist Directions: For each term or category displayed, write a one to two sentences explaining why it would be important to know each term as a population ecologist

6. Exploring Our Inner Pop. Ecologist Population Ecologist: Panda Bears Why would we care how often the endangered species, the panda bear, is born?

7. Exploring Our Inner Pop. Ecologist Population Ecologist: Panda Bears Why would we care how often the endangered species, the panda bear, dies?

8. Exploring Our Inner Pop. Ecologist Population Ecologist: Deer and Does Male deer are killed more often than female deer Why would it be important to know how many male and female deer there are?

9. Exploring Our Inner Pop. Ecologist Population Ecologist: Fruit Flies Fruit flies gather around fruit aggressively Why would it be important to know dense a population of fruit flies are?

10. Exploring Our Inner Pop. Ecologist Population Ecologist: Humans Humans leave and enter various locations Why would it be important to know when people are entering or leaving a country?

11. Exploring Our Inner Pop. Ecologist Population Ecologist: Elephants vs Mice Elephant offspring take years to develop and mature. Few offspring. Mice offspring take months to develop and mature. Numerous offspring

12. Exploring Our Inner Pop. Ecologist Population Ecologist: Elephants vs Mice Why would it be important to know the potential amount of offspring of both animals?

13. Notes Take out your notebooks and set up the next page in Cornell Notes style The Heading will be your main points. The notes on the power point are the notes you take in the big section of Cornell Notes

14. Natality and Mortality Natality - # of individuals added to the population through reproduction over a period of time Birthrate - # of individuals born per 1000 per year Ex: 2000 individuals gave birth to 20 newborns. The birthrate is 10/1000 or 1%. Most species produce many more offspring than are needed

15. Natality and Mortality Mortality - # of deaths in a population in a period of time Deathrate - # of individuals that die per 1000 per year Ex: Out of 10,000 individuals, 10 die per year. The birthrate is 1/1000 or.01%.

16. Sex Ratio Sex Ratio : Relative number of males and females Most species are 1:1 male to female ratio. Having a irregular balance can cause some animals or plants to go extinct Humans are 106:100 male to females, but males tend to die more often it equalizes to 1:1

17. Population Density and Distribution Population Density refers to the number of individuals of a population that inhabit a certain unit of land or water area

18. Population Density and Distribution Emigration: movement of people out of a population Immigration: movement of people into a population

19. Biotic Potential Each species has a biotic potential or inherent reproductive capacity. Biotic Potential assumes there are unlimited resources and no mortality What is a species potential to reproduce offspring?

20. Vocabulary in APES

21. Vocabulary Words Lecture One: Natality Birthrate Mortality Deathrate Sex Ratio Population Density Emigration Immigration Biotic Potential Vocabulary words for the Unit are always due the day of the Unit Exam

22. Elaborate your own study Directions: Choose one animal or invent one and determine population factors of your chosen animals

23. Exit Slip And then Push Praise
