HMSShas beendeveloped in Hawaiioy onestaff of the CurriculumResearch and Development Group, University of Hawaii. in consultation with teachers from Hawaii public and private schools, University of Hawaii faculty, andcommunity professionals. Thedesign of the HMSSmaterials is basedon the premisethat studyof the oceansprovides opportunity for studentsof all abilities to activelyengage in multidisciplinary scientific inquiry while learning the basic conceptsof science, hh«ll d h«l . 1 . 1«1 d~ii 1 «h 1 h. hh lhd INTRODUCTION TO THE HNSS STUDENT Marine Science refers to a wide ran in stud af the earth's water environment with emphasis on study of the sea. Marine Science includes content rawn from biology, physics, chemistry, meteorology, geology, cartography, oceanography, aquaculture and marine engineering. You will carry out investigations, design experiments, make instruments, and make interpretations of your findings. As the program progresses, you will be placed in different roles to get a clearer picture of what science means in modern society, Your chief role will be that of a marine scientist seeking to understand and mgke predictions about our ocean world, but you will also assume the roles of engineer, technician, and citizen to get insights into how the knowledge of science is used in our society. STUDY AIDS To help you study and rapidly understand procedures, several aids are provided. The first time a new science word is introduced, it is generally underlined. 2. This book is not to be written in. Tables and figures which you write on appear full size in your workbook and are identified in the text with the ~ sign. 3. Each chapter contains a set of activities. Each activity has six basic parts: ACtiVity This statement tells you what the acti vity is. It is a boxed-in statement. BqCkgf Dolls - This is an introduction to the activity, pqgei iq] S The things you need to perform the activity. PrOCedure This is a set of directions to aid in carrying out the activity. Sgtllqpy QUest jons These questions aid in sumnarizing and interpreting your knowledge and findings. FUtfidel- Irlyest.jgqgjogs -This is a set of additional questions, invest~gations,and challengesthat can extend the meaning of experiments and widen the significance of work completed. LABORATORYSAFETY The following safety precautions apply to all laboratory classes: 1. Wear safety goggles whenever you are working with chemica1 reagents. 2. Weara laboratory apron whendoing laboratory investigations. If chemicals are spiIled, the apron protects both clothing and skin. 3. Standwhen doing laboratory work. Standingavoids having chemicalsspi'lied in laps. 4. Always wear shoes with closed tops in the laboratory. 5. If chemicals should be spilled on clothing or skin, wash immediately with large quantities of water. This dilutes, and washes away the chemicals. 6. Never taste any chemical unless instructed to do so, 7. Tie or pin long hair at the back of your headso that it will not accidentally foll into chemicalsor flames. 8. Knowwhere the fire extinguisher and fire blanket are and how to use them in case of an emergency. TABLE OF CONTENTS Preface .

Haps are models that permit us to better visualize parts of the earth' s surface. In this chapter we will make and study a series of maps to get clearer pictures of the geography of earth's oceans.
