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 begin the lesson by identifying greenhouse gases. In groups, they observe and record the effect of the gases on the atmosphere and the temperature of the Earth. They participate in activities that describe the role of...
