Students explore the differences between lentic and lotic ecosystems. In this ecology lesson students study the water systems in Pennsylvania.

Students learn about watershed, as well as the different forms and uses of water. In this water forms lesson, students brainstorm water sources and uses. Students read the book Water Dance and discuss water examples. Students complete a...

Students create and conduct experiments on a "classroom river habitat." They manipulate the biotic and abiotic factors so that they are able to compare an artificially prepared river model to a naturally occurring lotic ecosystem.

Students assemble a classroom river model as an example of a lotic system. They control and measure biotic and abiotic information for the in-class system and compare data with a lotic system in a natural environment.
