1. Video Population Study

2. Warm up Are you a member of a community? More than one? Are you in two different communities when you are at home and school? Can you be anywhere that you are not in a community? It depends on the limits of the community, but most likely yes. They can be thought of as 2 different communities OR two locations in the same community. Probably not. You will always be IN a community even if you are not a MEMBER of a community. Ex: swimming in the ocean.

3. Ways to Study Ecosystems Bring a population in the lab to study. The population is isolated from the ecosystem in which it naturally lives. Create a mini version of the ecosystem. This allows you to study how the populations interacts with the abiotic parts. Study the population in it’s natural surroundings. This means traveling to where the population lives. We are going to watch a movie made in 1984 about Jane Goodall who did this with chimpanzees.

4. Movie Please review page 13. You can fill in this sheet as we watch the movie. Some questions are not addressed specifically in the movie. You will have to take what you have learned so far and apply it to the questions being asked. Notice at the end of the move how Jane Goodall uses the word community. Toward the end, she uses it in the common rather than the scientific sense.

5. Review Question 1: 26 years, 1960 Question 2: Binoculars, tape recorder, camera, field notes Find a high viewing point, indirect observations Question 3: Three To study the impact of learned behavior over time and compare Question 4: Observational: you go to population and study Experimental: Limited focus and controlled outcome

6. Review Question 5: Use of tools, ate meat, nonverbal communication, aggressive Question 6: Biotic: termites, baboons, Abiotic: storms, rainwater in trees, empty cans Question 7: Individual: Flo Population: The Chimps Community: All the chimps, baboons, termites, plants Ecosystem: The community and all the interactions both biotic and abiotic

7. More Questions Did Jane become part of the community of chimps? When she revealed herself to the chimps, she became part of the community and the interaction changed over time. How did her presence affect the chimps? At first they would hide and be afraid Then they stayed close to her Later they came to camp for food This caused aggressive behavior

8. More Questions Why do you think Jane chose to study in Africa rather than in a zoo? She wanted to learn about their life in the wild and how they acted naturally in their natural surroundings. How did she use the term “community” in the movie? Did she use it scientifically? She used it in a way meaning “social community.” A better term would have been population.
