Hiking hgzinzal Qcienrn Like Chemistry, Physics emphasized the practical importance of the discipline in everyday situations. Learning the fundamen- tals involved in the science were the items of prime concern at the beginning. Observation and understanding what had actually taken place were the goals to be achieved. Under the direction of Br. O'Donnell and Br, Reilly, a great deal of time and emphasis was spent on the area of mechanics. After a thorough examination of this topic, students moved on into such advanced subjects as op- tics, heat, light, and atomic theory. Knowledge of each of the topics was reinforc- ed through problems assigned to develop an inquisitive attitude within each student. Labs were frequently done which forced the Seniors to use the knowledge they had gained through lectures and assigned problems. Practical applications of Physics was the highlight of the year as students were pushed to their limits in an attempt to build bridges made of balsa wood. To achieve the project required the utilization of the rules dealing with stress, as well as equilibrium. As in years past, Physics has remained one of the most popular Senior electives. Students have regularly taken it in prepara- tion for further studies in engineering and science. Top: A student figures out a complicated equation. Bottom Left: Br.

Hikingz 'SZ: Art is a subject at St. Laurence that tru- ly gives the student the chance to express himself creatively. There were three art teachers. Mr. Smerz, Mr. Scott, and Mr. Martinez who all shared the task of developing the creative abilities of the many students at St. Laurence who have chosen the Art electives offered. Freshmen are introduced to Art in the 'i T Q- 'flu 'ix ' 3 N W 2- x 'If' the State nf the Art Art Foundations course. That is followed Sophomore year with the course Art II. This course is for those who wish to in- crease their knowledge on the more in- tricate parts of art. The highest level of art taught at the school is Commercial Art. This course helps familiarize the student with more Art techniques, color separa- tions, layouts and other aspects.

Relating insight into current chemical in- dustry topics, classes were presented through lectures, films, demonstrations, and labs which gave an understanding of how chemists solve problems in todays industry. Items of discussion included such mind boggling topics as Avegadro's hypothesis, the Gas Laws, balancing chemical equa- tions, and chemical equilibrium. Special interest was given to the chemist's and physicist's all important device, the red, white, and blue Periodic Table of elements. Labs allowed a first hand experience as to the work of chemists and chemical engineers. With an emphasis always placed on the practical uses of chemistry, Juniors learned the basis of theory along with its everyday application. Ranging from such fundamentals as acid-base titra- tions and pressure-volume relationships to deoderant production and the synthesis of nylon, student labs covered all the bases. Throughout the year, Br. Wielatz, Br. Fagan, and Br. Mooney, attempted and managed to relate an understanding and interest for the practicallity of chemistry in everyday life, Upper Left: Mike Cwiertniak and Bruce Lehrner make nylon in chemistry.
