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 pieces that we often overlook. Tardigrades and other microorganisms are some of the most numerous and most biodiverse organisms on Earth. This unit explores the biodiversity of these microscopic organisms as students learn to isolate the microscopic world living in lichens.
