Bodacious Biomes Lesson

What exactly is a biome again Mrs. Usher?

A biome is living community characterized by distinctive plant and animal species and maintained under the climatic conditions of the region.

Err...What does that mean Mrs. Usher?

Let's review, a biome is an environment that supports the needs of certain plants and animals. The biome’s environment is a result of its location on the Earth and its climate.

Not everyone agrees about how many biomes are on the Earth or exactly what they are called. Generally, most people agree that there are five major biomes on Earth. They include:

  1. Aquatic
  2. Desert
  3. Grassland
  4. Polar Regions
  5. Forest

 

Now that we have reviewed, let's focuss on the polar regions biome today. It is your goal to be able to tell me where the polar regions are located on a globe and about the temperature and water characteristics of the polar regions by the end of the lesson . You must also be able to make a list of at least three plants and six animlas that live in the polar regions.

Location:

The Polar regions biome is located at the very northern and southern parts of our planet. Polar regions include the tundra, arctic and Antarctic areas. The black areas are the polar regions.

Location of the polar regions

Temperature:

In a word, the temperature of the polar regions is cold. Can you guess how cold? It can be -90°F (-68° C) in the winter in the polar regions. The average winter temperature is -30° F (-34°C). There is not much percipitation in the polar regions, but what does fall is in the form of snow.

Water Characteristics:

Most of the water found in the polar regions is in the form of ice. The oceans in the polar regions are liquid, but can still be cold enough to have ice floating at the surface.

Plants and Animals:

There is little variety of plant life (for example, small plants, lichens, and mosses).

Animals that live in the polar region (for example reindeer, seals, polar bears, arctic foxes, killer whales,
and penguins) are adapted to these conditions by having extra fat or thick fur for insulation.

This site was developed by Kay Usher, a 4th grade teacher at Redcliffe Elementary School. It is part of a life science unit on biomes. Students in my class are also working on creating a book, reading and viewing a variety of materials, and conducting several experiments all relating to Bodacious Biomes.
