1. Sorting out Life 2.2

2. Remember to write complete sentences when doing your bell work.
Bell work 27 March 1, 2016
* You will need your composition books today.*
Take out your bell work from yesterday, skip a line, write Tuesday and answer the following questions: (Use your composition books and the textbooks).
Review the definition of community, and describe the community that you are a part of:
Community: all the interacting populations in a specified area
Are you a member of a community? More than one community?
Are you in different communities when you are home and when you are at school?
Can you be anywhere that you are not in a community?
Remember to write complete sentences when doing your bell work.

3. 18. Reading in Science Resources
“Life in a Community”

4. 2. Population studies
Scientist conduct population studies in many ways.
One way is to bring a population into the laboratory for observation.
The population is isolated from the ecosystem in which it lives naturally.
This is how you are studying your milkweed-bug populations in the habitat bags.

5. 2. Population studies
A second way to study a population is to create a miniature version of the ecosystem it lives in.
This allows you to see how the population interacts with other populations and with the abiotic parts of its ecosystem.
You will be building minihabitats in a few days, and you will study some population here in class.

6. 2. Population studies
A third way to study a population is in its natural surroundings.
This involves going where the population lives and making observations.
We are going to watch a video about one very famous scientist, Jane Goodall, who studies chimpanzees living and in their natural ecosystem.

7. 3. Focus Question 2.2
How is the milkweed-bug-habitat study similar to and different from Jane Goodall’s population study?
Put this in your notebooks and as you watch the video compare our population study to Jane Goodall’s.

8. 4. Student Sheet, Among the Wild Chimpanzees
Look over the questions before we begin the video
Some will not be directly addressed in the video
You will have to bring together the video and your own prior knowledge to develop answers

9. 5 Video Among the Wild Chimpanzees
Pay particular attention to the way Jane Goodall uses the term community
Toward the end of the video, she uses it in the common rather than the scientific sense for the word community.
Watch first 30 minutes, stop after the chimp uses the leave to soak up water

10. 6. questions
Write the answers to the questions on the Among the Wild Chimpanzees sheet

Bell work 27 March 3, 2016
* You will need your composition books today.*
Take out your bell work from yesterday, skip a line, write Thursday and answer the following questions: (Use your composition books and the textbooks).
How many generations of Flo’s family did Jane observe in the video? Why was it important to study the same family group for so long?
Define and provide at least one example for each: individual, population, community, and ecosystem in Jane Goodall’s chimpanzee study.
How are observational studies of populations different from experimental studies?

12. At the end of the second part. Discuss the questions
7 Discuss the video
At the end of the second part.
Discuss the questions
Did you use population, community, and ecosystem, correctly

13. Jane’s study was an observational study.
7 Discuss the video
Jane’s study was an observational study.
How is Jane’s study of the chimps different from a controlled experiment?

14. 7 Discuss the video
How is Jane’s study of the chimps different from a controlled experiment? Because you can’t control things, you can’t always determine the effect of one particular factor, such as food availability, or interactions with other populations (including humans). An observational study documents all the interactions in the study area with a minimum amount of disturbance. In a controlled experiment the observer can standardize all but one variable, such as area, temperature, light and dark, and food. In an observational study, these things cannot be controlled.

15. 7 Discuss the video
Did Jane become part of the community in which the chimpanzees lived? If so, at what point?

16. 7 Discuss the video
Did Jane become part of the community in which the chimpanzees lived? If so, at what point?
When she first made herself visible to the chimps and they reacted to her presence, she was a part of the community.
The interaction changed with time as the chimps came into camp.

17. How did Jane’s presence affect the population of chimps?
7 Discuss the video
How did Jane’s presence affect the population of chimps?

18. 7 Discuss the video
How did Jane’s presence affect the population of chimps? At first they would hide and avoid her. When they realized she wasn’t a threat, they stayed, and she could observe them. Later they began to come into camp for food. This caused some aggressive behavior on the part of the chimps.

19. 7 Discuss the video
Why do you think Jane chose to do her study in Africa rather than at a zoo or wild animal park?

20. 7 Discuss the video
Why do you think Jane chose to do her study in Africa rather than at a zoo or wild animal park? She could not learn about chimps’ in the wild by studying them in a zoo. She wanted to find out about their natural history and behavior in their natural surroundings.

21. 7 Discuss the video
How did she use the term community in the video? Was it the scientific or common usage of the term?

22. 7 Discuss the video
How did she use the term community in the video? Was it the scientific or common usage of the term?
She used it meaning “social community.”
“I started by studying one community. Later in 1972 the community divided into two.”
A better ecological term would be population but whether the division made two populations or not would depend on how geographically distant they were or the size of the study.

23. 8. Notebook entries
Review your notebook sheet 4, Among the Wild Chimpanzees, and make changes if needed. Complete sentences, if needed write under your paper or on the next page. Make sure it is in your table of contents.

24. 8. Notebook entries: check for
Review your notebook sheet 4, Among the Wild Chimpanzees, and make changes if needed.
You should recognize the key differences between an observational study and a controlled experiment.
Identify the biotic and abiotic interactions in the Gombe ecosystem
Correctly use the vocabulary terms learned in Part 1 of the investigation

25. 9. Conclusions
Did you notice things about how Jane Goodall studied the chimpanzees that might help you as you study your populations of milkweed bugs.
Keep Goodall’s studies in your mind when you build your own minihabitats, which you will observe and study for an extended time.
