"Biomes of the World in Action" is a fun, informative series that takes students on a fast-paced eco-adventure around the world exploring the many characteristics that make these large regions of the world different from one another. From the tundra and rainforest to grasslands and deserts, students will learn that each biome is unique because of its climate as well as its diverse collection of plant and animal species. Stunning footage will help students experience these "major life zones." Each program includes a stimulating experiment that students can replicate in the classroom, as well as information about an investigation data sheet available online that can be used for assessment purposes. This series is based on the concepts outlined in the "National Science Education Standards" for life science.
Freshwater Ecosystems 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.
