Lecture Materials: (U2 M3) Frogs - The Thin Green Line

Lecture Materials.jpg

It is the greatest mass extinction since the dinosaurs. Population by population, species by species, amphibians are vanishing off the face of the earth. Despite international alarm and a decade and a half of scientists scrambling for answers, the steady hemorrhaging of amphibians continues like a leaky faucet that cannot be fixed or a wound that will not heal. Large scale die-offs of frogs around the world have prompted scientists to take desperate measures to try to save those frogs they can, even bathing frogs in Clorox solutions and keeping them in Tupperware boxes under carefully controlled conditions to prevent the spread of a deadly fungus. Will it ever be safe to return the frogs back to the ecosystem from which they were taken?

Follow NATURE as it examines the conservation efforts of amphibian species across the globe. As you view the film, answer the questions in "Frogs: The Thin Green Line Video Guide" (Google Doc) to consider potential pitfalls of human intervention in nature.

It is recommended that you print out this worksheet and answer the analysis questions by hand as you complete the video guide. This video guide is not to be turned in or graded. There will be questions on the Credit Unit Assessment regarding this Video.
