Based upon the recognition that the sea has great potential as a future source of energy, minerals, and water, this document was developed to provide students with learning experiences in oceanography. It contains background information about ocean tides, waves, chemistry, depths, and plant and animal life. The book provides the teacher with hands-on activities, experiments, drawings, and worksheet exercises that deal with such subjects as: (1) the topography of the sea; (2) ocean currents; (3) finding places by means of latitude and longitude; (4) salt from seawater; (5) ions in seawater; (6) a test for the chloride ion; (7) waves; (8) how depth affects water pressure; (9) making drift bottles and secchi discs; (10) measuring ocean depths and speed; (11) nautical terms; (12) icebergs; (13) the Titanic's message in radio code; (14) sailor's jargon; (15) endangered species of the sea; and (16) careers in oceanography. Included is a student certificate for being involved in the oceanography activities, reproducible handouts and quizzes, and an answer key. (TW)
