5.1
Bear Necessities
Polar Bears Alive.  A non-profit organization dedicated to the worldwide protection
of the polar bear and its arctic habitat.

The Official Polar Bear Page.  Polar bears are the world's largest land carnivore. Find out about Klondike & Snow - two bears born at the Denver Zoo who were raised by humans.

5.2
The Organization of Life
Living Things: Habitats & Ecosystems

Model Module.  This module is one of a series within environmental biology and is designed to provide students with knowledge and understanding of aquatic ecosystems.

5.3
Adaptations for Survival
Adaptation Game.  In order to help you better understand the term adaptation and how it is used in the animal world, you will identify adaptations and create a new animal.

TrackStar: Animal Adaptations.  This track organizes Web sites that could be useful to
students as they research information on animal adaptations.

5.4
A Landfill Ecosystem
A Landfill Is More Than a Dump!!!  Plan an experiment to investigate what happens to waste in a landfill and a dump.

Rotten Truth (About Garbage).  A School Trash Audit.

5.6
A Landfill Ecosystem
Food Web Wonders. What exactly is a food web, you ask?

Food Web & Chains.  The plants and animals in a given ecosystem are linked by their feeding relationships.

5.7
Microbes in Ecosystems
Microbes - Invisible Invaders Amazing Allies. Get an overview of this travelling exhibit on microbes, including cartoons and activities on the history of deadly diseases and healthy microbes.

The Microbe Zoo.  An educational resource about ecology and microbiology. Includes information about microbes and the habitats they dwell in as well as dozens of images of microbes.

5.8
Nutrient Recycling and Plant Growth
Fertilizer - Agriculture Net Links.  Companies, associations, research, and controversies surrounding fertilizer.

Nutrient Cycling.  Although water and sunlight often set limits to the amount of plant growth on land, the abundance of certain chemical elements, known as nutrient elements, is generally limiting when water and sunlight are abundant.

Field Biologist
Krakauer, Alan.  Scruffy field biologist likes to photograph cool critters. Learn about his academic career and projects.
5.11
Pesticides: Poisons in the Food Chain
All You Can Eat.  What if you did eat an apple a day? You'll be stunned to see how many pesticides you eat in a year.

Website on Biodiversity.  Website with information on several aspects of biodiversity: biological, ecological, physical, chemical, social-economical, ethical issues.

5.12
The Water Cycle
Ground Water -Primer-Hydrologic Cycle. Water is constantly moving within and above the earth in a cycle called the hydrologic cycle.

Water: Each Drop Counts!  How many days do you think you can survive without a drink of water? When you finally get that drink, could it be the same water the dinosaurs drank?

5.13
Choosing a Waste Disposal Site
Waste Isolation Pilot Plan.  Visit this site in New Mexico to see a radioactive waste disposal facility which offers general information, a fact sheet, new releases, photographs, contacts, and related sites.
5.14
Rethinking Before Recycling
Biodegradable Materials.  Learn how to make, test, and evaluate biodegradable films and gels in order to design materials that control the time release of a dye, simulating controlled drug delivery.

Crab Shell Fibers - Composite Materials.  Huh? Visit this site and find out about a Biodegradable Composite for Burn Wound Dressing.

5.15
Garbage and the Community
Garbage: How can my Community reduce
waste.
 Facts about garbage and suggestions
for improving the handling and disposal of
waste materials.

Canadian Waste Services.  Meet the Garbage Engineers

Garbage: The Game.  A game about garbage.

5.16
Acid in the Water Cycle
Canadian Coalition on Acid Rain.  Presents the history of one of Canada's first acid rain awareness groups, the results of many of its studies, and other acid-rain related issues.

Acid Rain 2000.  Join this group of schools across Europe in monitoring acid rain to increase students' awareness of its harmful impacts, or read acid rain facts.

You Can and Acid Rain.  Question: How can rain be acid? Answer: That's a question more and more Canadians are asking the United States. More and more rain in Eastern Canada is acidic.

Acid Rain General Information - Environment Net Links.  Links to introductory information about acid rain and its consequences.

5.18
The Carbon Cycle

5.19
Solutions for Global Warming

Carbon - Carbon Cycle.  Provides information regarding earth's carbon cycle and the use of carbon dioxide in photosynthesis and complex carbohydrate generation.

Chemical Carousel A Trip Around the Carbon Cycle.  Meet Captain Carbon, the man of steel... well, only 1.5% of steel. On this adventure, you will explore both the traditional, scientific side of the carbon cycle as well as enjoy an inside tour through every process.

Greenhouse Effect.  Explains the causes of the problem and the difference between global warming and ozone depletion. Find out some possible solutions.

What is the Greenhouse Effect?  The greenhouse effect has been described as potentially the most dangerous environmental problem facing mankind.

NASA Earth Observatory.  Monitor regional and global changes on our planet almost as they happen. Here you can explore with NASA scientists the causes and effects of climatic and
environmental change through the use of real satellite data.

Acid in the Water Cycle
Plant Succession.  Wetland, Forest & Other Biomes: "A major community of living organisms; a complex of climax communities of plants and animals in a major region."

Beech-Maple Forest.  An excellent example of the climax stage of ecological succession. In this case, Beech and Maple trees will dominate the area until something happens to destroy it.

5.21
Logging Old Growth Forest
Old Growth Forests.  Only 22% of the world's old growth forests are still intact in self-sufficient sized tracts. -70% of the world's remaining old growth forests are in Russia, Canada, and Brazil.

Ontario's Ancient Forests.  Through the mist rising off the lake where you’re camping, a loon wails. Another answers. Here, in 1988, Dr. Peter Quinby found a forest that authorities claimed didn’t exist: an old-growth white-pine forest.
