 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 DVD Series in the Schlessinger Science Library. 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. |
"The pace...will hold students attention...women are shown in non-traditional roles. The material is accurate and current, and presented in a logical manner. The visuals are excellent...a great addition to school library collections."- School Library Journal
