An interactive introduction to oceanography covers such topics as the chemical and physical qualities of the sea and ocean floor, the characteristics of currents, and other more.
Book Description
Editorial Reviews
From School Library Journal
Grade 5-6-This introduction to marine sciences invites readers to conduct experiments that reflect the concepts and theories presented. The activities amplify the explanations by demonstrating what the narrative does not always explain. When the behavior of sea water and its chemical composition are described, the accompanying project is the simple creation of sea water by stirring two tablespoons of salt into one quart of water. The demonstration of how gases behave in water of different temperatures is another simple kitchen experiment. The chapters build upon one another, and the projects become more complex as well. Certain concepts are effectively simplified and clearly described, such as the Coriolis effect. Environmental issues are addressed in the chapter on undersea resources, which covers food, fresh water, and sources of power. A dramatic, full-color photograph begins each chapter; the other illustrations, diagrams, and photographs mostly appear in utilitarian shades of gray.?Frances E.

From Booklist
Gr. 5^-9. The study of the ocean integrates many traditional sciences, and this attractive volume devotes separate chapters to seawater physics and chemistry, as well as to geology (including recent discoveries about the ocean floor), ocean currents and their effect on world weather, and undersea resources and the need to conserve them. Set off in screened boxes throughout the text are hands-on experiments and activities at various levels of difficulty (What happens to the salt when seawater freezes? How do you make a model tide gauge?). The design is very spacious, with lots of subheads, thick paper, and bright color and black-and-white photographs and diagrams throughout. The writing style is informal (occasionally too exclamatory), and some photographs show middle-graders involved in activities; but the information is quite technical, and older readers will find this an accessible introduction to marine science. There's a long bibliography of youth titles. Hazel Rochman
