Introduction
The use of a case study can bring a subject alive and allow for in-depth
analysis and evaluation. In this lesson, students will study the
controversial history and impact of the building of the Aswan High Dam
in Egypt in order to investigate several ecological concepts.
Their culminating activity will take the form of a team presentation
that outlines a solution to one of the environmental problems caused by
the dam. In the process of this lesson, they will also be forced
to evaluate Internet sources for accuracy.

"6. Stability
in an ecosystem is a balance between competing effects. As a basis for
understanding this concept:
-
Students know biodiversity
is
the sum total of different kinds of organisms and is affected by alterations
of habitats
-
Students know how
to analyze changes in an ecosystem resulting from changes in climate,
human activity, introduction of nonnative species, or changes in population
size."
Instructional
Objectives
At the end of this
activity, students will:
-
Recognize location of
Aswan High Dam and other key locations on map of Egypt.
-
Evaluate Internet sources
for accuracy.
-
Evaluate the changes
in the Nile ecosystem as a result of the building of the Aswan High Dam.
-
Collaborate in a team
to formute a possible solution to one of these changes.

Introductory
Activity
Activity
#1: Cybertour of Aswan
The first thing
that students must do is become familiar with the geography of Egypt and
the city of Aswan. Students will accomplish this goal by taking a
"cyber tour" of this area. While they take their tour, they will
need to take note of the some of points of interest along the way.
Use the questions provided on the activity site for this purpose.

Activities
Activity
#2: Gathering Information
In this activity,
students will gather information about the history and resulting impact
of the building of the Aswan Dam. They will be placed in teams of
four to five students and be assigned an article from the Internet.
They will use questions provided on the activity site to guide their inquiry.
Once each member
in each group has finished their article and write-up, the class will discuss
the information that they found. Students should add new information
learned during the discussion to their worksheet. Students will realize
that the information that they gather will be different based on their
sources-- introducing them to the idea of bias.
Activity
#3: Evaluating Your Source
After the class discussion, students should
realize the importance of getting information from more than one source.
Students will take the article that they were assigned in Activity #2 and
evaluate it for Accuracy, Relevance, and Bias using questions provided
in the site.
Culminating
Activity
At the end of this
project, students will collaborate with a team to formulate a possible
solution to one of the environmental problems resulting from the building
of the dam.
-
This will take the form
of a team presentation to the class explaining their assigned problem
and resulting solution.
-
The presentation must
include visual aids and be effective enough to convince the class
of its feasibility.
-
Students will be required
to ask each team questions to determine whether the solution would
be effective.

Assessment
Assessment will include evaluations of
the following:
-
Pre-test and Post-test
