This 17:30 video provides an entertaining lecture on how to look at the world from the perspective of a plant to provide students and others a fresh look at life. The theme is: What if human consciousness isn't the end-all and be-all of Darwinism? W...hat if we are all just pawns in corn's clever strategy game to rule the Earth? A good class room discussion starter that could be used for science/environment classes and cause and effect lessons.

What are ecological systems, and what types of organisms live in these environments? This interactive activity adapted from the University of Alberta identifies the living and nonliving components of an animated ecosystem. Users are also invited to l...ook at examples of mimicry, and identify which living things are producers and which are consumers. To help users complete the activity, key terms, including biotic and abiotic components, are defined.

In the Susquehanna River, there is much polluted sediment build up compiled and slowly seeping into the Chesapeake Bay. However, large portions of the sediment are still compacted at three hydroelectric dams along the river in Pennsylvania and Maryla...nd: Safe Harbor Dam, Holtwood Dam and Conowingo Dam. At these dams, much of the collected mud holds many pollutants, such as heavy metals, fertilizers, coal dusts, and waste. Most dangerous to the river and bay habitats, Phosphorous is also found trapped in the sediment behind these dams. In 1972, Tropical Storm Agnes released thousands of tons of this sediment into the bay ecosystem. There is much concern that another storm could let loose some or all of the remaining thousands of tons of this polluted mud. (5:21)
