This section provides instructions for building simple, inexpensive devices to use in collecting plankton, aquatic invertebrates, and water samples. Some of these make excellent projects for technology classes or youth groups who are interested in "doing something" positive to protect their environment.

Most of these items are available to borrow through Delta Environmental.
