Earth Science: Ecosystems and Biomes

by

Palaeontology, geology, geography, meteorology, environmental issues, ecosystems and biomes are just a few of the fascinating topics encompassed by the field of Earth Science. These topics thread their way through school curricula at every grade level and provide teachers with many possibilities for building classroom units of study. The following background information and list of resources might be helpful when integrating the learning standards from each subject area to create a literature-based theme around ecosystems and biomes.

WHAT ARE ECOSYSTEMS?

Ecosystems can be defined as the interactions between living and non-living things in a specific place. The energy that flows through an ecosystem by means of these interactions comes primarily from the sun through photosynthesis. Ecosystems can be tiny (a puddle, a tree stump, etc.) or large (a mountain range, a lake, etc.).

WHAT ARE BIOMES?

Biomes are described as very large areas of the earth’s surface (usually found in bands of latitude around the planet) defined by their climate and the community of plants and animals that live there. Every part of the earth’s surface, terrestrial and aquatic, is part of a biome. The five major types of biomes are desert, forest, grassland, tundra and aquatic (salt and freshwater). Each biome is made up of a large number of ecosystems with similar characteristics. Forest, grassland, tundra and aquatic biomes are found in Canada.

Teaching Resources

The World’s Biomes. This website provides detailed information about the five major types of biomes: aquatic, desert, forest, grassland and tundra. The characteristics of each biome are described and the importance of conserving, and maintaining, healthy biomes is emphasized. ucmp.berkeley.edu

FOREST BIOMES

Forests are large areas of land where the vegetation is predominantly trees. Scientists classify forest biomes into subgroups according to their latitude (tropical, temperate, boreal). Each type of forest supports a community of plants and animals that is suited to that particular climate and soil type. Forests cover 3.5 million square kilometres (60%) of Canada’s landscape.

National Forest Week: September 18 to 24, 2018. This annual week of public awareness was originally established in the 1920s and was formerly known as Forest Fire Prevention Week. www.cif-ifc.org/national-forest-week/

National Tree Day: September 26, 2018. This is an annual day of celebration for all Canadians, to appreciate the benefits that trees provide (cultural, social, ecological, economic, etc.). treecanada.ca/engagement-research/national-tree-day/

Forest Regions: The Canadian Encyclopedia. Canada’s forest biome can be divided into eight regions that are characterized by their geography and dominant tree species. A map and description of each region are provided in the article in The Canadian Encyclopedia. This is an excellent resource for teachers and intermediate/senior students. thecanadianencyclopedia.ca/en/article/forest-regions/

GRASSLAND BIOMES

Grasslands are open tracts of land where the main type of vegetation consists of grasses and wildflowers. A major loss of native grasslands has occurred in Canada due to agriculture, forest encroachment, cattle grazing, and the invasion of non-native plants. Losses include 97% of the tall grasses in southern Ontario, 70% of prairie grasslands and 19% of the bunchgrass and sagebrush in British Columbia.

TUNDRA BIOMES

The tundra is vast, treeless land covering large areas in the far North, including Nunavut, the Yukon, the Northwest Territories, Northeastern Manitoba, Northern Ontario, Northern Quebec and Northern Labrador in Canada. A number of animals and low growing plants with small leaves and short root systems have adapted to living in the cold, harsh climate of the tundra biome.

Biomes Activity

Goal: To introduce primary school students to the concept of Canadian biomes.

Carson Crosses Canada
by Linda Bailey, illustrated by Kass Reich
Tundra Books, 2017
penguinrandomhouse.ca

Synopsis: Carson the dog and his friend Annie Magruder travel from Tofino, on Vancouver Island, to visit Annie’s sister in Newfoundland. They camp along the way and experience many diverse geographical regions. A route map is provided.

Step 1: Read the book to the class. Track the journey on the route map.

Step 2: Return to a few of the pages that contain illustrations of water bodies (ocean, lake, waterfall). Have the students examine each picture in detail. Brainstorm a list of things that can be seen in the pictures. Record the list on chart paper or the chalkboard. Consider what sounds might be heard in the pictures and add those words to the list.

Step 3: Return to the page with the picture of the prairies. Repeat the above process.

Step 4: Provide each student with the following word list. Each word, or set of words, is printed inside a box: Pacific Ocean, grasshopper, salt air, flat, lake, big sky, waterfall, grain, Atlantic Ocean. Have the students cut out the word boxes and sort the words into two groups on their desk tops.

Step 5: Have the students share their word sorts with a partner. Ask them to justify their sorts by explaining the rule they used for sorting the words.

Step 6: Introduce the terms “grassland” and “aquatic.” Make sure that the students understand what the words mean before asking them to re-sort the words under these two headings.

Step 7: Have each student share their second word sort with a partner. Have them explain whether this sort is the same or different from their original sort, and why.

Step 8: Explain to the class that one way that scientists think about Canada’s landscape is by looking at the climate, the soil and the living things that thrive in different large areas. The animals and plants that live in each area are adapted to the unique conditions of the area. These large areas are called biomes. Grasslands are one kind of biome. Bodies of fresh and salt water are aquatic biomes. Forests and the tundra are also biomes.
