Abstract
To find out about the microscopic life in the valuable estuary environment, it is usually necessary to be near the water. This dry lab offers an alternative, using authentic data and a simulation of plankton sampling. From the types of organisms found in the sample, middle school students can infer relationships in the biological and physical environment of an estuary. A Science Activities classic, the activity was originally published as "The Estuary" in the February/March 1983 issue.
