Engage: Show anchor
video to the students. After
watching the video, ask them some general questions about the interaction
between organism and environment. How animals gather food shows one way
organisms interact with their environment.
When you look at your backyard or a park,
you may wonder why plants and animals live the way they do. You may also wonder why a fish lays
several thousand eggs and why they haven't overpopulated the earth. Compared to human like us, is it
possible for us to overpopulate the earth?
These questions are about ecology which
is the scientific study of interactions between organisms and their
environment.
|
1. When you go to nearby park, what kind of animals or plants do you usually see? Can you give me an example? 2. Do you know how this animal/plant searches for food? |
1. Response varies. 2. Response varies. |

Explore: We are going to examine how organisms
affect each other and the physical environment.
We will also examine relationships that
exist in the community, ecosystem, and biosphere.
Before I said anything about community, ecosystem,
biosphere, and organization of life, I would like you to divide into 7
groups. Each group will have a
term to work with. Your job as a
group is to define the term and give examples to support your definition. Afterward, you should draw or cut out
pictures that will help the class remember your term. You may use your book as a guideline. After your poster is complete, you
will be asked to explain it to the class. Also, your group should write two questions about their
term so you can test your classmates after your presentation. Your poster doesnŐt need to be fancy,
but you must try to come up with an explanation for your term and give
examples to support your explanation.
You will have about 20 minutes (or the rest of class) to
finish up this exercise. Time: ______minutes |

Explain: (Student lead discussion) Students will present their poster and each group will have 5 minutes. (Teacher lead discussion) Show a transparency of pg. 59 from the textbook. Have the students try to identify the organization of life and explain to the students that this is the level of organization (the hierarchy of life). All organisms depend on others for food, shelter, reproduction, or protection. There are 3 levels of organization provided by the ecologists.
We all know a habitat is the place where organisms live, but habitat can be further divided into niches. A niche is the role a species plays in a community. Time: ______minutes |
1. Can anyone give me an example of Interactions within population? 2. How about individuals interact within communities? 3. What would be the habitat and niche for squirrel? |
2. When the size of one population grows so large it begins affecting the food supply for another species in community. 3. Habitat
– forest, city park with trees |

Evaluate: Pop quiz at end of the lesson.

Pop quiz questions 1. List 3 abiotic factors in an ecosystem. 2. Give an example that would demonstrate the differences between niche and habitat. 3. Compare and contrast population and communities. |
