Overview

When most students imagine national parks and nature in general they probably think of large animals such as bear and deer. Although bear, deer, and other visible animals are important parts of the ecosystem, there are other important pieces that we often overlook. Tardigrades and other microorganisms are some of the most numerous and most biodiverse organisms on Earth. During this study students will isolate resident tardigrades and other microscopic life found in lichens.

1) understand the biodiversity of the Great Smoky Mountains National Park
2) learn several characteristics of tardigrades and other microscopic life
3) learn the vocabulary related to the tardigrade study

5) isolate, view and classify microscopic life such as tardigrades, rotifers, nemotodes and protozoans
6) understand the definition and classification of extremophiles
