Achievements in the Math depart¬ ment were accomplished through the use of proper logic and clear thinking. Academic Math courses were of¬ fered at four levels. Freshmen strug¬ gled through first year Algebra, at¬ tempting to understand the purpose of equations. Sophomores continued with Geometry, learning theorems and working with proofs. As the jun¬ iors progressed to Advanced Algebra, they were exposed to the principles of the slide rule, imaginary numbers, and logarithms. Seniors concluded their high school Math with Trig¬ onometry. A taste of college algebra was introduced as students studied the processes of mathematical logic and circular functions.

With the help of scale models and charts. Biology students examine the structures of different species of animals and plants. Science Department runs the gamut with To instill in the student an un¬ derstanding of science, classes were offered at all levels. General Science gave a founda¬ tion of knowledge to those students who felt they were not ready for Bi¬ ology. The Health and Safety course provided an opportunity to learn about the physical, social, mental, and emotional well-being of the individual. Biology classes made use of the new lab facilities. Physiology was offered in summer Advanced Biology. The geological history of the earth and its relationship to the universe was the subject of die Earth Science course. Now within reach, the moon represents a prime interest for Earth Science students. 30
