Wide Variety of Math Li L Mary Peterson, Dave Cassling, and Bob Bates concentrate on homework. When people referred to the good old days, the)' weren't considering math offered in high school. Formerly there was only one field — general math — but times have changed. The sophomore continually wonders if answers exist. He has a choice of Algebra I and II or Plane Geometry I and II, where he learns deductive rea- soning. The junior, who may be studying Algebra III and IV as semester courses, has the idea answers can’t be found but keeps trying anyway. Seniors know that answers can't be found to some problems but like the challenge. They may enroll in trigonometry and analytical or solid geometry. Mathematics I and II supplies a review of mathe- matical fundamentals. Also, offered for a second year, Temac allows self-study. Elizabeth Barnes Business Math Geometry Rick Zimmerman ponders over the trig explanation Jim Wit tig has worked out for the problem.

New Techniques A bug is not just any six-lcggcd crea- ture. explains Mr. Nick Avelchas to his biology students. Using new physics laboratory equipment are Tom Fritzsche and Gary Goldsmith, seniors. Nick Avelchas Biology DuWayne Carnes Physics Reflecting the role that scientific development plays in our modern world, Central’s science department boasted its largest enrollment ever. A total of 47 sections was divided into 21 classes of biology, nine of chemistry, five of physics, four of earth science, four of physiology, and four of zoology. New, modern equipment was added to this expand- ing department. Two telescopes were purchased for the future astronomers, one reflecting and the other refracting. For physics students, additional instru- ments, such as a wave machine and miniature wind tunnel, were added. CHS is also modernizing its courses of study. The physics department is improving through a better course outline with new textbooks. The chemistry de- partment is proud of its two new sections, better known as CBA” (chemical bond approach). Future modernization for Central may include new courses of study such as advanced science.” With these improvements, CHS will be able to produce more future scientists than ever.
