Relationships

This video details the "brown food chain," explaining how rotting detritus such as pond scum and animal poop contribute enormous amounts of energy to our ecosystems.

During your unit on adaptations, evolution, or predator-prey relationships, this video would be an excellent one to show your students.  In it, is a discussion as to the possible reasons for zebras having stripes.

This is a video that discusses the importance of sharks in the ocean ecosystem.  The questions, "What if there were no sharks?" is explored.

This video discusses how temperatures in lakes affect the flow of the lake's ecosystem.

In this online science activity, students get to take pictures of animals and plants and learn something about their adaptations that permit them to live inside a specific ecosystem.

This video does a good job explaining what is meant by natural selection in the evolutionary process and why scientists believe in the Theory of Evolution.  Descent with Modification, Common Descent, Galapagos Island Turtles, Charles Darwin, Selective Breeding, are all concepts discussed in the video.

This video visually discusses what ecosystems and biomes are. The video is 16 minutes long.  It talks about the 7 major biomes on Earth, arctic, coniferous forest, deciduous forest, desert, grasslands, aquatic, and the rainforests.  Permafrost and savanna are also discussed.  At the very end of the video, the narrator demonstrates how to make a terrarium.

This is a visually appealing and dramatic video that introduces your students to the study of biomes.  This is a great video to show as you get started on a new unit of ecology.

In this video, the definition of an ecosystem is visually demonstrated and discussed as well as the different biomes.  This is a good introduction to your unit on ecosystems and biomes.

With this video, students will learn about how energy and matter get transferred through different organisms via the food chain.  Sun Energy, Producers, Primary Consumers, Herbivores, Secondary Consumers, Carnivores, Tertiary Consumers, Top/Apex Predators, and The Ten Percent Rule are all discussed and explained in this video.
