PRODUCT SUMMARY


Freshwater ecosystems can be as small as a puddle or as large as a raging river. Ponds, lakes and streams occur on every continent, and are home to a host of fish, algae and other water organisms. In Freshwater Ecosystems, students will explore these fascinating and diverse habitats and learn about the biotic and abiotic factors that make up these ecosystems. A hands-on experiment shows students how to test the amount of dissolved oxygen in two different bodies of water, while a visit with a freshwater naturalist examines the importance of wetlands around the world. One of eight volumes in the Biomes of the World in Action Video Series in the Schlessinger Science Library. Part of the Schlessinger Science Library in Action Collection. This title is based on the concepts outlined in the National Science Education Standards for Life Science: structure & function in living systems, reproduction & heredity, regulation & behavior, populations & ecosystems, and diversity & adaptations of organisms. A Teacher's Guide is included and available online.

Gr 5-8-These videos cover the main biomes of the world. Coniferous Forests looks at the evergreen trees, which are the dominant plants of this biome. Many other plants and animals are also shown. In Deciduous Forests, the most notable feature is the changing leaf colors. The different layers of this biome are shown, along with the reduction of the size of these forests. Deserts cover about 20% of the world's land surface. The video provides a good explanation of what constitutes a desert, and shows how plants and animals are adapted to live there. Freshwater Ecosystems features ponds, lakes, rivers, and wetlands. Grasslands explains how this biome has been reduced from 42% to 12% of the world's land surface. Most of our food and clothing is grown in this biome. The Marine Ecosystems biome accounts for 97% of Earth's water. The four types of marine environments are shown in detail, including seashores, coral reefs, open oceans, and estuaries. Rainforest Biomes features the diversity of plant and animal life found there, and shows and describes the four main layers. Tundra looks at the two main types arctic and alpine. The severe weather conditions are examined. Lichens, the dominant life form, are shown. The series presents a good geographical description of each biome and examines abiotic and biotic factors. The pace of the videos will hold student attention. Male and female narrators have clear and distinct voices. The videos show a diversity of racial and cultural backgrounds, and women are shown in non-traditional roles. The material is accurate and current, and presented in a logical manner. The visuals are excellent. Each video contains classroom experiments that can be done by students. This series could be used to introduce or wrap-up a unit on biomes. Social studies teachers will also find much of the information pertinent. This series will be a great addition to school library collections.
