Each of the three major sections--chemistry, biology,and physics--addresses concepts that are generally covered inthose courses but incorporates aspects of marinescience. Within each 6 section, major concepts such as density, pH,photosynthesis, respiratim and sound are supported by student activities.Each activity contains background reading materials, amaterial.: list, procedures for completing the activity, and extensionideas. At the end of each concept division, references, resources,and education competencies are listed. The chemistry sectionincludes activities on chemical reactions in the marine environment; densitydynamics and estuaries; pH, equilibrium and ocean buffering; andbehavior of gases in the marine environment. The biology sectionincludes activities on new discoveries; biochemistry; animaladaptations; geologic history and the oceans; seashells and scientific names;behavior of ocean creatures; and man and the ocean. The physics sectionincludes activities on the motion of the ocean, sound, and light inthe sea.
