Algebra I, II Plane Geometry Solid Geometry General Mathematics Consumers' Mathematics The basic fundamentals of all mathematics are addition, subtraction, multiplication, and division. GENERAL MATHEMATICS provides the opportunity for the mastery of these skills. Thought problems furnished challenging examples for every mind. In AI.GEBRA, unknovsms were discovered through the use of equations. These equations employed logarithms, exponents , and graphs. Theorems based on postulates and axioms proved geometric expressions correct. The most common expression used in GEOMETRY is con- gruent figures. In a congruent figure, lines and angles are exactly alike, where as, in a similar figure, everything is only in proportion. Per- ception was sharpened through the use of three dimensional objects . CONSUMERS' MATH classes participated in studying various graphs and graphing vital statistics. Mathematics throughout the home was stressed by figuring interest rates, budgets, and insurance policies. UPPER: Under the watchful eyes of Doris and Tom, Sharon confidently sets the meters.

SOCIAL SCIENCE V 2?'fZy'h-gg 20 World History American History is oo o G World Problems World Geography One of the interesting units of the WORLD PROBLEMS class informed students of the many problems facing the average family today. Topics such as budgeting, picking a mate, insurance, and health standards brought varied class discussions . Mid-January found class members knocking on doors of Greenfield residents for census information. Each year students of the WORLD GEOGRAPHY class take a tour around the world, with emphasis on the Western Hemisphere. The first stop on the itinerary was Canada, famous for her 'Red Mounties' and endless wheat fields. Before touring the U.S. , the class stopped in quaint Quebec, with its picture- esque architecture and familiar French customs. Class assignments from the monthly Reader's Digest provided many little known facts of our own native land. In addition to studying these countries, customs and highlights of Central and South American countries were dwelt upon. WORLD HISTORY was born with the beginning of time. As the first traces of civilization grew, great empires rose and fell, such as, the Babylonian, Grecian, and Roman Empires. All barbaric nations illustrated totalitarianismp the first evidences of democracy according to modern times originated in the city-state of Athens, Greece. The past, present and the future are entwined within ow' current events . Exploration and colonization of a new continent resulted in the source of AMERICAN HISTORY. The growth of this country was characterized in the maturing of its government. The expansion of the United States involved her deeply within world affairs . On her Eastern shore lies the mediary of universal problems, the U.N. Dottiegene Don Carlos gave an informative yet entertaining talk about the U.N. and Washington, D.C. Kwhich she visitedl for the various social science classes. Through these presentations, she punctuated the importance of each citizen's knowledge and voice in governmental affairs . UPPER: Roy Dean describes the location of the invasions by the cruel barbarians to the world history class. MIDDLE: Sharon Kay makes an amusing remark which illustrates her point of view in the discussion. lMcC1el1and, Newbury, Mr. Ray, Loukl LOWER: Far away places are located by the use of geographical materials and references. fW1etzke, Rohr, Paxtonj

pi!-M SCIENCE f 7'.1Q'?L Z2 Bill Don Carlos points out various eye sections to Joyce Rice and Gail Nielson. What's the matter, Joyce ? General Science Unsolved mysteries of the universe stimulate- ed the interest of freshman GENERAL SCIENCE students. Our galaxy, the Milky Way, is com- posed of trillions of stars, meteors, and planets of which nine are known. The sun, the attracting force of om' solar system, is the ray of earth's life. The simplest constituent of the living earth is plant life. The' development of this fundament- tal organism grew into a more complex being. BIOLOGY classes studied this miraculous growth. One of the most fascinating divisions is the Homo sapiens, human being. The revelations of human knowledge have resulted from the amazingly simple cycle of life based on a single cell. Energy and matter comprise everything in the universe. Mechanics, electricity, heat, sound and light are the five divisions of PHYSICS. There are six simple machines . The principles of these machines promote the learning of the law of momentum which in turn advances the same to the law of acceleration. Through the aid of ex- perimentation enumerable intangibles can be visualized.
