Just like when you swim in a river, the water is Just like when you swim in a river, the water is warmer at the top-most, shallow parts, because the most sunlight reaches warmer at the top-most, shallow parts, because the most sunlight reaches and warms it. As you move deeper in the water, the temperature grows and warms it.

The Marine Biome The marine biome covers 75% of the

Earth! Marine biomes have a high salt

concentration. Can you think of any bodies of water that have salt in them?

Marine biomes are usually found in oceans, the biggest of all the biomes!

Oceans are separated by 4 zones of deepness. Just like in the freshwater biome, the temperature of the marine biome depend on the deepness of the water. The deeper the water is, the colder the temperature.

The Desert Biome Deserts have very dry and hot climates. Because

of the heat and dryness, the desert’s plants and animals have had to adapt to its climate.

Most deserts only get 10 inches of water a year! During the day it becomes very hot in the desert

and can get up to 100 degrees Fahrenheit! At night, however, the desert can have

temperatures as low as 40 degrees Fahrenheit! The desert contains almost as many plants and

animals as the rainforests do! The desert biome is found in northern Africa,

western North America, western Asia, the center of Australia, and on the west coast of South America .

Can you think of a plant or animal that has adapted to having only a little water throughout the year?

The Forest Biome

There are two types of forest biomes: the deciduous forest biome and the rainforest biome.

The Deciduous Forest Biome

The deciduous forest biomes are found in the eastern United States and Canada.

Deciduous trees shed their leaves in the fall and grow new leaves in the spring.

Rainfall in the deciduous forests is 30 to 40 inches per year.

The average summer temperature here is about 70 degrees Fahrenheit and about 25-20 degrees Fahrenheit during the winter.

Chipmunk Squirrel Black Bear Bald Eagle Deer

The Rainforest Biome The rainforest has very tall trees and a climate

of warm weather all year round. The rainforests also have over 100 inches of rain

each year! Almost all rainforests are found near the

equator. The rainforest has different layers. The top layer

is called the emergent layer and forms a canopy of trees that are 100-250 feet tall!

Each layer of the rainforest captures sunlight and blocks some sunlight from reaching the layer below it. Because the trees form a canopy over the rainforest, there is less sunlight toward the bottom layers. The least amount of sunlight touches the rainforest’s ground- it is usually completely in shadow!

The Rainforest Biome

What animals are found here?

Elephants Tiger Chimpanzee Sloth Rhinoceros

The Rainforest Biome

What plants are found here?

Bamboo Coconut Trees Sugar Cane Fig Trees

The Grassland Biome The grassland biomes are large lands of grasses, flowers,

and herbs. The grasslands usually gets 10-30 inches of rain each

year. Because of this the grasslands have droughts, which also cause fires that prevent forests from growing here.

There are two different types of grasslands: tall-grass, and short-grass. Tall-grass environments are humid and very wet, while short-grass environments are dry, with hotter summers and colder winters than the tall-grass.

In the winter, grassland temperatures can be as low as -40° F. In the summer, however, it can reach temperatures up to 70° F.

There are two seasons in the grassland biome: a growing season and a dormant season. During the growing season, there is no frost and plants can grow, but during the dormant season, plants can’t grow because it is too cold.

Grasslands can be found in the center of continents.

Sunflowers Clover Crazy Weed Asters

The Tundra Biome The tundra is the coldest of all biomes. The tundra biome has little rainfall, very cold

temperatures, and frost-molded land. There are two types of tundra's: the arctic

tundra and the alpine tundra. The arctic tundra is near the north pole with an average winter temperature of -30 degrees Fahrenheit and an average temperature of 3-12 degrees Fahrenheit during the summer. The alpine tundra can be found on very high mountaintops where trees can’t grow. At night, the temperature gets below 32 degrees Fahrenheit.

The arctic tundra has a permanent layer of frozen ground called permafrost.

Discussion Questions

How have animals adapted to their biome?

What about plants? What would happen if we destroyed or

lost a biome? Could an animal adapt to living in a

different biome? Why or why not? Could we find each biome in the

United States or are they in different parts of the world? Give examples.

Assessment

Students will be given a blank world map page. They must then follow the legend and color in correct location of where each biome is found.

Students will then be given a hand-made exam which asks them to list 2-3 animals and plants, and general facts about each biome.
