How diverse is the world we live in compared to the way things used to be? Young biologists explore diverse organisms and relate the structure of each organism to its ability to survive in our current environmental conditions....

This smart slide show outlines energy flow in ecosystems. It addresses the sun as the primary source of all energy, flows into explanations of photosynthesis and respiration, and explores trophic feeding levels and productivity....

Scientists discover more than 15,000 new species each year. Viewers learn about seven new species discovered in cities, often right next to where people live. As part of a larger playlist, a video discusses the techniques researchers use...

How are living organisms grouped? In this eight-minute video clip, the system of grouping them according to similarities and relationships is broken down in a simple and straightforward manner. Sal explains the definition of species and...

Everybody needs somebody... especially in nature! Show your young ecologists the finer points of NGSS standard LS2A, Interdependent Relationships in Ecosystems, using the helpful ideas in the video. The narrator discusses the...

Our scholarly friends head to the lake to go fishing and are unpleasantly surprised by the algae filling the water. They talk about primary and secondary succession as different ways that ecosystems are changed. Show the short video,...

With the world's largest collection of geysers, many visitors end up overlooking the wildlife natural to Yellowstone National Park. Join Mr. Andersen as he shows your class about the different species living in the park and illustrates...
