2 Description of Course Course Title: Oceanography - # 410 Description: This course is designed to study the physical, chemical and geological processes at work in the oceans, and their effect on marine plants and animals. The history of oceanographic research, instrumentation, seafloor topography, seafloor spreading, the chemistry of seawater, waves, currents, tides, and life in the sea are topics included in this course. Goals: Work in areas of physical, geological, and biological oceanography to identify the effects of sea and energy processes on the health of the rest of the planet. ist the unique characteristics of water, and describe their effects relative to life on our planet. Identify the more common life forms found on the east coast of the nited States and compare the various habitats of these organisms. Requirements: Prerequisites: All students who have not taken the course, Integrated Science, may take Oceanography. Text: Spaulding and Namowitz, Earth Science, McDougal-ittell Publishing, 2003 Key to evels of Achievement (isted with each learning objective) Awareness (A): earning (): nderstanding (): Reinforcement (R): Students are introduced to concepts, forms, and patterns. Students are involved in a sequence of steps and practice activities which involved further development and allow evaluation of process. Students demonstrate ability to apply acquired concepts and skills to individual assignments and projects on an independent level. Students maintain and broaden understanding of concepts and skills to accomplish tasks at a greater level of sophistication.
