SCIENCE CHEMISTRY Chemistry students at Senior are very fortunate in having a recently installed, modern laboratory, equipped with the best apparatus. The chemis- try course, available to juniors and seniors for two semesters, is taught by Mr. Gus Wolff, Senior High alumnus. The classroom theory work is supple- mented with many interesting experi- ments. The students work in pairs to solve experimental problems in analy- sis and synthesis, many experiments which would pose problems if per- formed in mass are done by Mr. Wolff before the class. At the end of the year, each student is required to carry out one of the projects that are listed by the instruc- tor and to hand in a detailed report on his results. Ann Murray, George LaPrelI, and Judy Schepple listen while Mr. Dolzell explains the oscilloscope. BIOLOGY Biology is offered as an elective subject in all three years at Senior. Mr. Rhys Hutchison and Mr. C. O. Johnson provide a study of living things, with their composition, their form, their functions, and their habits, with the products they produce, and their relationships to one another and to their physical environments. Di- section of frogs and worms and other small animals gives the students ex- cellent experience in the study of vertebrates and invertebrates. Mr. C. O. Johnson leads a discussion in one of his biology classes. From left to right are Dorothy Brenke, Rob Johnson, and Karl Funk. Four busy chemists, Denny Mulvehill, Shirley Specht, John Williams and Pat Granes, are working on o tough chemistry experiment. PHYSICS Physics, taught by Mr. Wil- bur Dalzell, is the science which deals with matter and energy and with p h ys i c a I changes in matter. lt is an elective subject offered to jun- iors and seniors. The seven major units in physics are mechanics, heat, sound, light, electricity, and nuclear physics. Experiments are a vital part of the course because they help the students see more clearly what they are studying.

COMMERCIAL SUBJECTS Upper left hand corner-Members of Mrs. Glaser's bookkeeping class respond in a class discussion. Upper right hand corner-Linda Ostrander, Lois Volkert, and Art Witherall look over a problem for Business Law Bottom left hand corner-Kay Delaney, Karen Chambers, Barbara Loeffelholz, Roger Kirby, and Tom Steffens discuss a math problem. Bottom right hand corner-Mary Beau, Joann Kress, and Chuck Vincent do some calculating an various types of office machines. BOOKKEEPING The principles and practices of bookkeeping are related to the daily lives of all of us. The study of bookkeeping helps students under- stand how business functions in everyday life and what business contributes to society. In bookkeeping, which is a two-semester course, students learn to deal with complete transactions through practice sets, containing business papers that give them actual contact with many of the commonly used business forms. BUSINESS MATH Whether one enters the field of business as a means of livelihood or plays the role of the consumer, he cannot escape the almost daily use of arithmetic. This course is designed to emphasize the application of principles of arithmetic to such problems as taxes, insurance, savings and in- vestments, and problems of selling. BUSINESS LAW Business or Commercial Law is offered exclusively to seniors at Senior. Business Law is concerned with the rules that apply to business situations and transactions, the legal meaning to the commonplace activities as well as those that arise less frequently. Several elements of this type of law are contracts, relationship between buyer and seller, property, and insurance. MACHINE CALCULATION Fundamental processes of office machines are first introduced in their simplest forms and then carefully developed throughout the course so that a complete knowledge in the correct use of the calculator as an essential office machine is attained. There are both manually and electrically operated calculators of the keydriven and the crank-driven types, and adding machines of the ten-key and full keyboard types.
