Seekings Through Science ' Well, Kris, I used the formula, AF(X) = AQ = AT -h TQ = F(X) AX + TQ. ' Now for a few sprinklings of yeast and the beverage for Friday night is complete. And six molecules of, uhh, now what does this C stand for? says John Brindley, Biology teacher. In a quiet mood, Eugene Worden, Trigonometry teacher, reflects on life ' s little (math) problems. Charles Lehfeld Biology Harry Mortensen Geometry Walter Franz Physical Science, Physics Orval Knee General Math, Algebra Larry Hutzell, Chemistry teacher, expounds on the prin- ciples of chemistry to students. Curiosity leads to scientific research. If this statement is true science students had curious minds and performed countless experiments to satisfy them. Biology classes were largely con- cerned with the study of genetics. Chemistry and physics classes produced mixtures of solutions, gases, and other materials to await breathlessly the sometimes surprising results. Mr. Hutzell ' s students received an additional thrill when he created a miniature erupting volcano. Math is the study of numerals. However, the courses were not quite that easy. They included Geometry, Algebra and Trigonometry, which is the study of the system of complex numbers.

Social Sciences Stress Awareness Elsie Wilmeth American History, Psychology John Phillips American History Seminar, Sociology Topics in the news: Vietnam, Apollo space mis- sions, the presidential election, all became the subjects of heated panel discussions and debates in government classes. The lively at- mosphere stimulated learning as the introduc- tion of the contract grading system allowed students to work at their own pace according to their own ability. The students learned not only when history oc- curred but how and why. The areas not coverd by these courses were touched upon by several new classes: Emerging Nations, American History Seminar, and Geography Project. Black History taught black and white students about a beautiful and important culture with the aid of tapes, records, films and books. Government students begin the opening round of a debate.

John Moon, let ' s tighten up. 6th hour gym. booming, exciting, breathtaking ! While the newly established classes held the attraction of permitting PE once a week, doing push-ups at 7:15 in the morning had its discomforts. However, in comparison to other aspects of the PE program, this was a small detail. Strenuous exercises such as knee bends and jumping jacks plus active sports from swim- ming to tennis demonstrated physical fitness wasn ' t easy to acquire. Skills for developing muscle control and graceful movement were practiced on the trampoline and parallel bars, in addition, boys PE used body-building equipment. As a result of student effort, aches and com- plaints changed to energetic enjoyment. Above: Coach Helms and Glann can ' t seem to avoid football, even off the field. Holding football: Mike Minear.
