    3. Learning Objectives The student will list at least 5 biomes. The student will describe at least 3 characteristics for each of 5 biomes. The student will describe how different environments support different varieties of organisms

    4. What are Biomes? Biomes are regions in the world that share similar plant structures, plant spacing, animals, climate and weather.

    5. How are Biomes Classified? Biomes are classified as either terrestrial or aquatic. Terrestrial comes from the Latin word, terrestris, from terra the earth.

    6. How Many Biomes Are There? Scientists disagree over the exact number of biomes, but in general they include around 8-10 biomes.

    7. Tundra Very cold Low diversity Simple vegetation Short growing season

    8. Grasslands There are two types of grasslands. The tropical grasslands (savannah) and the temperate grasslands. Dominated by gasses savannah has a wet and dry season Temperate grassland has a hot summer and cold winter

    9. Desert Animals are small Many animals are nocturnal Temperatures can be very hot or very cold Plants are adapted to conserve water

    10. Tropical Forest Very rainy Little variation in climate Highly diverse species Soil is nutrient-poor and acidic

    11. Decidious Forest Temperature varies Soil is rich with decayed matter Plants consist of broad leave trees Includes animals such as squirrels, rabbits, skunks, and bear. Even precipitation throughout the year

    12. Coniferous Forest Also called the taiga or boreal forest The largest terrestrial biome Temperatures are low Precipitation is primarily snow Soil is nutrient poor and acidic Flora is mostly conifers Animals include woodpeckers, hawks, moose, bear and lynx.

    13. Marine Biome Consists of oceans, coral reefs, and estuaries The ocean is the largest of all ecosystems. The ocean contains a diverse array of plants and animals at various depth zones. Coral reefs consist mainly of coral. Estuaries are areas where fresh and salt water environments converge. Mangroves, oysters, crabs and marsh grasses are examples of species in this environment.

    14. Freshwater Biomes Includes ponds, and lakes; streams and rivers, and wetlands. Ponds and lakes have well lit zones and a variety of fish dominate this zone. Streams and rivers move in one direction. Wetlands are areas of standing water that support aquatic plants.

    15. ?ENGAGE Listen to the sounds in the El Yunque Rainforest in Puerto Rico. This is the only rainforest in the U.S. and its territories. http://www.hear.org/alienspeciesinhawaii/species/frogs/index.html#frogcalls

    16. ?EXPLORE Complete the Biome Box Activity.

    17. ?EXPLAIN List major biomes of the world. How does the climate of a biome affect the flora and fauna of the region? List unique characteristics of biomes.

    18. ?ELABORATE Complete the Pick Six activity. Pass out biome picture cards. Circulate and find students with pictures that represent the same biome. The first group to locate the members of their biome wins. Collect the biome picture cards and redistribute them for another round.

    19. ?EVALUATE Use the science journal and list 5 biomes describing at least 3 characteristics for each of the 5 biomes. Describe how different environments support different varieties of organisms.
