Frogs, like essentially all amphibians, are sensitive both to pollution and to habitat disturbance. As land is developed, many amphibian species disappear. In many Triangle area subdivisions, the only amphibians present in any numbers are these two little frogs and Fowler's toads. Surprisingly little is known about these frogs. Because early spring is the season with the most water and the fewest predators, so their tadpoles have the best chance to grow up in the puddle and ditches where the frogs lay their eggs.
Frogs are interesting to students, and many teachers use that interest as a teaching angle.
The 'Net references below are some good places to start looking for information and ideas on teaching about frogs and other amphibians. It's also good for students to realize that often we can find evidence of animals without actually seeing those animals, if we use our eyes and our ears.

A Thousand Friends of Frogs A wonderful site for teachers and students, maintained by the Global Environmental Education Center of Hamline University in St. Paul, Minnesota. The site has information on frogs, learning resources, a fine page of links, information on global concern over the decline of amphibians, and an Ask the Experts link.
