Www lt's All Protoplasm, From Protozoa to Mammalia Sister M. Alma Clare explains to Vicki Mathews how to find the actual size of a specimen proiected by the bioscope. The world of science has always fas- cinated students, and biology offered not only a new world of study, but also a new vocabulary. Although impressing friends with technical terms was great fun, the girls found that those same expressions sometimes caused bad moments on quiz- zes. The biology students studied all forms of life, beginning with the smallest, and pro- gressing to more complex botanical life. In the fall, leaf collections revealed an amazing number of trees present right here on campus, and even more in various back yards. From the plant life students turned their attention to simple animal life, beginning with amoeba, paramecium and other one-celled forms. As in the plant kingdom, the class moved from these sim- ple types through higher animals until, near the end of the year, a study of the human body was made. Advanced biology was offered for the first time at Saint Mary's this year. The course was difficult, due to the use of an advanced textbook, and made the regular biology work easy by comparison. Much use was made of current readings in scientific magazines. So this is what a polio virus locks like! ex- claim Barbara Dutrieux, Mary Joan Bookwalter, and Annette Furos, advanced biology students, as they make a close examination of a virus slide greatly magnified.

KI29CfiCS'D9ClCS Logic About Lines Leads to Logic About Life sl: Maureen Crowley, Janet Mennucci, and Sue Szabo take pride in the geometry design exhibit. Little did they realize that art would find its way into math class! With weird formulas such as s.a.a. is equal to s.a.a. and triangle DEF confronting them, the new geometry students came uncertainly, but well- prepared, to work, toting an impressing array of compasses, protractors, and rulers. Here it wasn't enough to draw a straight line-there had to be proof that it was straight! Triangles within circles and circles within triangles had to be carefully con- structed. Theorems and laws were interpreted, mem- orized, and applied constantly. Toward the end of the year geometry was an old friend, inspiring logical thinking and many angles of interest. in-s.. flmfazsu. far:-rr-mia...
