leasoning Produces Clear Thinkers r, as semester courses, where he masters the ncepts of algebra. As a senior, he may en- 11 in trigonometry for the first semester and en choose between solid and analytical ge- letry for the last semester. Other students may want to review arith- etic skills in business arithmetic. Also offered e Mathematics I and II, supplying a review mathematical fundamentals. This year saw the introduction of the Temac 2thod on an experimental basis in one algebra iss and one trigonometry class. Under this ethod of self-study, each student progresses his own speed, taking tests at intervals roughout the semester. Top Row: Mrs. Sharon Brown, algebra, geometry; Mr. James Brunner, geometry, golf coach; Mr. Beryle Conley, department head, algebra, trigo- nometry: Mr. Michael Erickson, geometry. Bottom Row: Mr. Dale Giesler. algebra, mathematics, assis- tant sophomore football coach; Mr. Harlan Gold- smith. trigonometry, city coordinator of mathematics: Mrs. Mary Hess, algebra; Mr. Thomas Murphy, mathematics, assistant varsity football coach, sopho- more wrestling coach. 17

The dissection of a pig embryo seems to be the point of interest for Phyllis Heinz and Gene Lucht in a zo- ology classroom. Scientists Hypothesize, Experiment, and Conclude The increase in need for scientific minds has brought about a greater emphasis on the Cen- tral High science department. Those students interested in life and life processes find an overall picture in biology, which includes the study of both animal and plant kingdoms. More specific one-semester courses may be selected in either zoology, a comparison of typical animal forms, or physiology, an in- vestigation of the human body. Earth science is a study of the physical development of the earth; its area of study covers both external and internal forces working to create and destroy our globe and, in addition, probes the mysteries of space. Physics and chemistry offer an analysis of matter and the physical laws of the universe. This year saw the debut of the experimental Chemical Bond Approach to chemistry at Central. Top Row: Mr. Nick Avclchas. biology, assistant varsity football coach, sophomore baseball coach; Mr. John Clancy earth science, physics; Mr. Warren Classon. biology, city coordinator of science; Mr. Ira Dunsworth, biology, phy- siology, assistant boys intramurals, assistant varsity track coach. Bottom Row: Mr. Frank Gorshe. department head, chemistry; Mr. Dennis Hoflfnagle. chemistry, bovs’ physical education, varsity swimming coach: Mr. Dallas Qucck. biology, zoology, sophomore football coach; Mr. Harvey Voris. biology. 19
