Foreign Tongues Gain Universal Importance With national attention ijeing given to the learning of a foreign language. Central ' s foreign language depart- ment teaches students the fundamentals of French, Spanish, and Latin. The department makes good use of the language laboratory, which provides the students with an opportunity to hear the language spoken as it should be and compare it with their own voices. Students are able to speak and read the language fluently and to understand its usage. By taking a two-year course in language, a person not only becomes knowledgable about the life but also the culture of other nations.

Science Opens New Perspectives Science, llie sliulv of life and phenomena, takes up a major part of academic life at Central. The department branches ont into the various phases of science — biology, chemistry, physics, and physiology. In biology the stu- dent learns of living creatures and their functions. Chemistry deals with the elements, their composition, and reaction. The student observes this through the various experiments performed. Forces. Newton ' s laws of gravity, and acceleration are taught in physics while phvsiology specializes in the human body — its func- tions and activities. General science is offered to seventh and eighth graders. The aim of the Science Depart- ment is to prepare the student for future events and to broaden his knowledge of our universe and of man himself.

Mathematics a Must for Advanced Studies Mathematir, sets the stage for practically all advanced courses and is an active program at Central. Although this department enaliles the student to learn the various fundamental processes involved in the solution of prob- lems, its major objective is to correlate this knowledge into a practical application of it. Included in advanced mathematics are four semesters of Algebra, solid and plane geometry, and trigonometry; however, these will be changed next year through a revision of all books, condensation of certain courses, and a mild introduction to new courses. Math plays a vital role in the student ' s life although quite often he is not aware that he is using the Pvlheoorean theorem or the Law of Functions. Mr. Grill points oul non mathematical error to his students Mrs. VonBelkum discusses the role mathematics plays in a person ' s evcrydoy life. Mr. Marcus, ninth grade Algebra teacher, explains the soli tion of a simultaneous equation. Mr. Schut shows his geometry doss how to determine the number of degrees in an arc. 2R
