| Lesson Plans:
A Look at the Population Density of the United States
Students will create maps showing the population density of the U.S.
at different scales. This will enable students to organize spatial
information in categories, analyze the information, and draw
conclusions.
Learning About Interlocking Dependency
Students study the Earth's biosphere to identify
examples of the concept, "interlocking dependency."
Water Quality For Freshwater Organisms
The purpose of this activity is to demonstrate to
students the effect increased water temperature has on the amount of
dissolved oxygen found in water and in turn upon the gill beat rate
of fish.
The Chesapeake Bay: A Time for Change
make predictions about the future of the Chesapeake Bay and their
local watershed based on current trends and consider the potential
impact of community action initiatives.
The Nile in Crisis
High school students should be able to analyze the
interrelationships between physical systems (such as rivers) and
human settlements and activities. This activity asks them to examine
the current water situation in the Nile River region, focusing on
the Blue Nile and the Egyptian Nile, and to investigate ways in
which the damming of the Nile has changed this river significantly
from the way it was in ancient times.
Coastal Development
In this lesson, students will examine two maps that illustrate the
tendency for people in the United States to settle near the coasts.
They will research some environmental impacts on coastal ecosystems
and conclude by writing reports on steps that are being taken to
mitigate these impacts in specific parts of the country.
Crane Cam: Intended and Unintended Effects of Conservation Efforts
n Nebraska, the Platte River Valley and Audubon's Rowe Sanctuary are
home to a migratory "pit-stop" for sandhill cranes. In this lesson,
students will use resources on the National Geographic
magazine feature Crane Cam to learn about how the land area in and
around the sanctuary has changed over time. Students will examine
the intended and unintended consequences of human environmental
intervention by studying crane activity in the Platte River Valley,
and by researching the effects of human intervention on bird
populations—and the effects of bird populations on humans.
The Aral Sea: What's Happening to Whom?
Students will research the situation in the Aral Sea region; explain
how health, agriculture, fishing, and ecosystems are affected; and
determine how specific individuals might be impacted. They will
conclude by pretending to be specialists called in to help, and
listing the things they think need to be done to help.
