Change in a Small Ecosystem, An Environmental Investigation.
National Wildlife Federation, Washington, DC.; Minnesota Environmental Sciences Foundation, Inc., Minneapolis.
This environmental unit is one of a series designed for integration within an existing curriculum. It is self-contained and students are encouraged to work at their own speed. The philosophy behind the series is based on an experience-oriented process that promotes independent student work. This particular unit explores the concept of succession in communities. The activities included develop the major concept by requiring students to set up small aquaria and to observe the changes that take place in these small communities. Sampling and population prediction techniques are included in the activities. Teacher information concerning background information, materials, and additional topics is given. This unit is designed for students, grades 5-9. A short bibliography is included. (MA)
