Diagnosing The Living Biology is the only compulsory science at St. Laurence. In this course, students learn about the liv- ing organisms in their environment. Unicellular organisms to the com- plex anatomy of the human are discussed.. Students learn about DNA reproduction, the cell struc- ture, the ecological web and the various body systems.Along with the lectures, students perform various dissections from a simple earthworm to the highlight of the year, the fetal pig. Some Honors Freshman Students were also allowed to take Biology this year. In addition to Biology, Human Physiology was also taught this year. This course focused entirely upon the human anatomy. In this way, students study the respiratory system, digestive system, and ner- vous system in depth, as it applies to the human body. 150 f Biology s W-s.. 3 'a HE. use gif ,.t 921- x Top Left: Gary Peplinski and Rus Mariano view the exterior of their frog before dissection.

FJ The physical man is also ex- emplified in the St. Laurence educa- tion. Students are required to take at least one year of gym, usually in their freshman year. By taking gym, many students are able to take ad vantage of the use of the weight Staying in Shape rooms, gym, and track.

Learning the Chemical nalys's This year as in past years, Junior students were con- fronted with the intriguing realm of Chemistry. The course was taught solely by Br. Mooney who had the difficult task of instructing both honors and A track courses. The concept of the atom and quantum mechanics filled the chemistry atmosphere. Students performed various labs analyzing solutions, fin- ding molecular weights and learning how to use a bunson burner. Junior chemists left this classroom with a slight knowledge of the atomical world around them. Avogadro's principle, Le Chatelier's princi- ple, moles, atomic weights, compounds and Van Der Wall's forces will forever dance in these fortunate students' heads.
