Introduction
As you have been learning in class, all living things depend on each other to survive. If just one link is missing, a whole chain can fall apart. This webquest will help you get a better understanding of just how important each part of an ecosystem is.
Standards
S4L1 Students will describe the roles of organisms and the flow of energy within an ecosystem.
a. Identify the roles of producers, consumers, and decomposers in a community.
b. Demonstrate the flow of energy through a food web/food chain beginning with sunlight and including producers, consumers, and decomposers.
c. Predict how changes in the environment would affect a community (ecosystem) of organisms.
d. Predict effects on a population if some of the plants or animals in the community are scarce or if there are too many.
S4L2 Students will identify factors that affect the survival or extinction of organisms such as adaptation, variation of behaviors (hibernation) and external features (camouflage and protection).
a. Identify external features of organisms that allow them to survive or reproduce better than other organisms that do not have these features. (e.g. camouflage, use of hibernation, protection, etc.)
b. Identify factors that may have led to the extinction of some organisms.
ELA4W1 The student produces writing that establishes an appropriate organizational structure, sets a context and engages the reader, maintains a coherent focus throughout, and signals a satisfying closure. The student:
b. Writes texts of a length appropriate to address the topic or tell the story.
c. Uses traditional structures for conveying information (e.g., chronological order, cause and effect, similarity and difference, and posing and answering a question).
d. Uses appropriate structures to ensure coherence (e.g., transition elements).
The student produces informational writing (e.g., report, procedures, correspondence) that:
a. Engages the reader by establishing a context, creating a speaker’s voice, and otherwise developing reader interest.
b. Frames a central question about an issue or situation.
c. Creates an organizing structure appropriate to a specific purpose, audience, and context.
d. Includes appropriate facts and details.
e. Excludes extraneous details and inappropriate information.
f. Uses a range of appropriate strategies, such as providing facts and details, describing or analyzing the subject, and narrating a relevant anecdote.
g. Draws from more than one source of information such as speakers, books, newspapers, and online materials.
h. Provides a sense of closure to the writing.
ELA4W4 The student consistently uses a writing process to develop, revise, and evaluate writing. The student
a. Plans and drafts independently and resourcefully.
b. Revises selected drafts to improve coherence and progression by adding, deleting, consolidating, and rearranging text.
c. Edits to correct errors in spelling, punctuation, etc.
Task
You are a famous ecosystems designer for zoos and aquariums around the world. The mayor and city council in Cleveland, Georgia have decided to increase tourism in the area by building a zoo and an aquarium to compete with those in Atlanta. They come to you for help because they want the best.
To be successful in this mission, you need to be a person who:
- Enjoys creative projects. These exhibits have to compete with Atlanta.
- Enjoys research. These exhibits have to be realistic and accurate.
- Can describe a project in writing.
Process
The city leaders in Cleveland want you to design an ecosystem in their new zoo and aquarium. However, because you are so busy, you only have time to work on one of the projects. Follow the links below to read the project requirements.
