Challenge Question:
What are the trade-offs of introducing a species into a new environment?
Overview:
Students will read a story about a boy who is a fisher in Lake Victoria. They will then read a bit more about the introduction of Nile Perch into Lake Victoria and the effects it has had. Students will then take on one of four roles and discuss how the introduction of the species affects each of those individuals. Students will then complete a set of analysis questions.

Assessment
Criteria |
Introducing a species into a new environment can have intended and unintended consequences to ecosystems and people |
Students will be able to explain that when nile perch were added to the lake, the amount of fish increased along with employment, money, and food for the locals. Students will also be able to explain that the introduction of perch caused cichlids to become extinct, algae increased, and there are now dead-spots in the lake. |
Populations of organisms can be categorized by the function they serve in an ecosystem |
Student will explain that perch function as predators, causing other fish populations to decline. |
Making decisions about complex issues often involves trade-offs – giving up one thing to gain another |
Students will complete question 6 using some of the following supporting evidence. |
Standard/EALR:
6-8 INQC Investigate |
Collecting, analyzing, and
displaying data are essential aspects of all investigations. |
Communicate results using pictures, tables, charts, diagrams,
graphic displays, and text that are clear, accurate, and informative. *a Recognize and interpret patterns
– as well as variations from previously learned or observed patterns
– in data, diagrams, symbols, and words. |
6-8 LS2A |
An ecosystem consists
of all the populations living within a specific area and the nonliving
factors they interact with. One geographical area may contain many ecosystems.
|
Explain that an ecosystem is a defined area that contains populations
of organisms and nonliving factors. Give examples of ecosystems
(e.g., Olympic National Forest, Puget Sound, one square foot of lawn) and
describe their boundaries and contents. |
6-8 LS2D |
Ecosystems are continuously changing. Causes of these changes
include nonliving factors such as the amount of light, range of
temperatures, and availability of water, as well as living factors such
as the disappearance of different species through disease, predation,
habitat destruction and overuse of resources or the introduction of
new species. |
Predict what may happen to an ecosystem if nonliving factors
change (e.g., the amount of light, range of temperatures, or availability
of water or habitat), or if one or more populations are removed
from or added to the ecosystem. |
