Human activities such as inequitable and unsustainable production and consumption of earth resources cause "environmental problems." There is need to develop research and innovative techniques towards public understanding of these environmental problems and sustainable development. This paper contains the first edition of…

Presents the story of "The Perpetual Salt Fountain" to illustrate some fairly typical ramifications and vagaries in the workings of science. Outlines the discovery of double diffusive convection and uses the fact that it had been observed in the laboratory a century before its independent rediscovery to emphasize the vagaries of…

Presents an innovative, inquiry-oriented lesson plan for using biotechnology to teach evolution. Using acrylamide gel electrophoresis, students learn how to isolate and compare different proteins from the muscle tissue of readily available seafood specimens to determine phylogenetic relationships. Uses a 5E (engagement, exploration, explanation,…

This module provides information on: (1) the origin of the oceans; (2) sources of minerals and salt found in the sea; and (3) the role and uses of salt in various cultures (stating, for example, that the expression "salt of the earth" describes a person who is considered one of the best). (JN)

Examines the gravitational effects and the way that local conditions interact with these effects to produce the tides characteristic of the British seas. Presents some effects of tides including the possibility of harnessing tidal energy and the effect of tidal friction on the use of the earth as a clock. (GS)

Brief descriptions and eight activities related to zooplankton, sharks, dune ecology, ocean currents, and sea products comprise this manual. Among the activities are harvesting seafood, making Japanese fish prints, and tracing marine currents with drift bottles. (WB)

This report is the result of a survey of educators using the Chesapeake Bay in environmental education courses. The goal of the survey was threefold: first, to identify persons using the Bay area in their educational programs; second, to ascertain the level of environmental education programs being offired; and third, to determine the services…

Discusses the nature of and activities in marine geology/geophysics, oceanographic engineering, physical oceanography, chemical oceanography, and biological oceanography. This information, which includes comments on major employment positions (academic, government, industry, consulting), is provided to help students select possible careers in…

This manual, developed for use in Alaskan secondary schools, is one of a continuing series designed to provide basic information about the marine environment and Alaskan marine resources. The first part of the manual presents information about tides, focusing on: the nature of tides; cause of tides; factors related to tidal movement; types of…

This annotated guide to current marine education resources is arranged in three sections--secondary, elementary, and professional--and indexed by subject. It lists 287 selected free-loan films, sale films, audio and video recordings, film loops, filmstrips, study prints, maps, charts, and other software, including government publications,…

This series of experiments seeks to provide laboratory exercises which demonstrate concepts in Earth Science, particularly oceanology. Materials used in the experiments are easily obtainable. Examples of experiments include: (1) comparison of water hardness; (2) preparation of fresh water from sea water; (3) determination of water pressure; (4)…

This activity is designed to use a collection of marine bivalve shells. From these shells, students can determine approximate ages of the shells, compare weather conditions to shell ages, and learn problems of this technique. (RH)

Discussed is one teacher's method of teaching students to use various marine and scientific apparati while studying important relationships within the ecosystem. A data retrieval chart is included with questions and problems to ask about the data, along with information on how to interpret the data chart. (MA)

Describes the procedures employed to make salt from seawater. Reviews the basic principles of seawater chemistry and discusses the techniques used to measure salinity. Identifies major saltworks locations and indicates the proper conditions needed for solar production of salt. (ML)
