Presents a hands-on activity in which students create a model of an ocean ecosystem to gain an understanding of how humans can alter biodiversity through their actions. Uses differing levels of fishing technology to explore the concepts of sustainability and overfishing. (Author/SOE)

Several investigations can be undertaken with live sea anemones. A sea anemone's feeding response, fighting power, color, and symbiotic relationships to other invertebrates (such as a marine hermit crab) can be investigated in the high school classroom. Background information and laboratory procedures are provided. (Author/JN)

Describes 10 predator/prey relationships that occur on the coast. Predators are compared to criminals and prey to their victims along with details of crime scenes. Accurately describes the habits and habitats of the criminals and presents games and activities that feature the relationships between predators and their prey. (Author/SOE)

Describes an approach to the study of squid that helps students of all ages develop richer ideas about the structure of living things, how living things are adapted to their habitats, and how they interact with other organisms. Highlights include the external and internal features of the squid, squid statements and statistics, and writing…

Presents students with six ballast water treatment methods to evaluate. Allows students to acquaint themselves with current Great Lakes topics while simultaneously partaking in decision-making processes that could affect them. Emphasizes not only an important environmental issue for the Great Lakes, but also the importance of decision-making…

Suggests that ecology clubs utilize skin or scuba diving techniques to do ecological research. (LS)

Discusses damages of oil tanker spillage to the marine organisms and scientists' research in oil pollution removal techniques. Included is a list of learning activities concerning the causes and effects of oil pollution and methods of solving the problem. (CC)

Outlines a 10-day unit in oceanography for the primary grades. Suggest stories, chalkboard work, topics for discussion, coloring projects, experiments, films, reference books, and topics for research projects. (CS)

Describes how high school biology students use the clam to study the bivalve body plan anatomy. Employs an open-ended investigation format that is rich with measurement opportunities including body mass, valve mass, and volume. (DDR)

Provides an OEAGLS (Oceanic Education Activities for Great Lakes Schools) activity showing how biological sampling can be taught using acquatic examples in a "dry lab." The activity, requiring use of mathematical/observational skills, simulates a plankton sample and stimulates discussions of how environmental/human factors can cause…

Provided are background information, equipment lists, and procedures for four activities for teaching aquatic ecology. Activities include "The Aquatic Food Chain Game"; "Two-Liter Aqua-Vivariums"; "A Sealed World"; and "Weaving a Web: Evaluation." (CW)
