This "Biomes - Match Up" worksheet challenges students to connect biome names with their corresponding images and scientific definitions.

To solve this matching problem, we need to look at the key words in each definition and match them to the correct biome name. Let's go through them one by one.

1. Definition: "Is a forest in a cool, rainy area. It has warm summers and cold winters (often snowy). This biome has 4 different seasons... A wide variety of mammals, birds, insects, and reptiles can be found..."
* Clue: The mention of "4 different seasons" and trees that lose leaves (implied by the variety of animals and seasonal changes) points to Deciduous Forests. Deciduous trees change with the seasons.

2. Definition: "Is found on every continent except Antarctica. Occurs when rainfall is very low... Mainly used for farm land to grow crops. There are very few trees and shrubs... savannas, pampas, campos, plains, steppes, prairies and veldts."
* Clue: The list of names like "savannas," "prairies," and "steppes" directly matches the alternative names given in the biome column for Grasslands (Savanna, Prairie). Also, "very few trees" is a key feature of grasslands.

3. Definition: "Are very dense, warm and wet forests. This biome is home to millions of plants and animals. This rainforest is divided into 4 layers... This biome is endangered."
* Clue: The words "dense," "warm and wet," and "rainforest" clearly point to Tropical Rainforests.

4. Definition: "About three quarters of the earth's surface is covered with water. This biome is divided into fresh water... and marine..."
* Clue: This definition explicitly talks about water covering the Earth and divides it into fresh and salt water. This matches Water (often called the Aquatic biome).

5. Definition: "Is the coldest of all the biomes. It means 'treeless plains' and includes Antarctica, the Arctic Circle... very cold temperatures, high winds and heavy snowfall. Plants grow low to the ground."
* Clue: "Coldest of all biomes," "treeless plains," and "Antarctica/Arctic" are the defining features of the Tundra.

6. Definition: "The driest biome which covers about 1/3 of the Earth's surface. Hot and dry environment with very little rain... extreme temperatures and lack of food."
* Clue: "Driest biome," "very little rain," and "hot and dry" describes the Desert.

7. Definition: "Is the largest land biome. Cold, harsh climate. Low rainfall and snow. Very cold and long winters. Animals include wolves, bears and huskies. Plants include coniferous (Christmas) trees, pines, spruce and fir trees."
* Clue: "Largest land biome," "coniferous trees," and "pines/spruce/fir" matches Taiga/Coniferous Forest.

Summary of Matches:
* Desert matches with: "The driest biome which covers about 1/3 of the Earth's surface..."
* Taiga/Coniferous Forest matches with: "Is the largest land biome. Cold, harsh climate... Plants include coniferous..."
* Tundra matches with: "Is the coldest of all the biomes. It means 'treeless plains'..."
* Grasslands (Savanna, Prairie) matches with: "Is found on every continent except Antarctica... savannas, pampas... prairies..."
* Tropical Rainforests matches with: "Are very dense, warm and wet forests... divided into 4 layers..."
* Deciduous Forests matches with: "Is a forest in a cool, rainy area... has 4 different seasons..."
* Water matches with: "About three quarters of the earth's surface is covered with water..."

Final Answer:
Here are the correct matches from top to bottom based on the definitions provided:

1. Desert → The driest biome which covers about 1/3 of the Earth's surface. Hot and dry environment with very little rain and extreme temperatures...
2. Taiga/Coniferous Forest → Is the largest land biome. Cold, harsh climate. Low rainfall and snow... Plants include coniferous (Christmas) trees, pines, spruce and fir trees.
3. Tundra → Is the coldest of all the biomes. It means "treeless plains" and includes Antarctica, the Arctic Circle and very high alpine mountain areas...
4. Grasslands (Savanna, Prairie) → Is found on every continent except Antarctica. Occurs when rainfall is very low... These biomes have many different words for this biome they include: savannas, pampas, campos, plains, steppes, prairies and veldts.
5. Tropical Rainforests → Are very dense, warm and wet forests. This biome is home to millions of plants and animals. This rainforest is divided into 4 layers...
6. Deciduous Forests → Is a forest in a cool, rainy area. It has warm summers and cold winters (often snowy). This biome has 4 different seasons...
7. Water → About three quarters of the earth's surface is covered with water. This biome is divided into fresh water... and marine...
