Science Courses Satisfy Students' Curiosity ln every adolescent there is a streak of curiosity. Many students found outlets for this curiosity in science courses. The three major science courses at East, biology, chem- istry and physics, deal with the world about us, its composition and why it behaves as it does. In biology classes students discovered the world of nature. As the wonders of plant growth and reproduction unfolded, micro- scopes were used to study the infinitesimal parts of leaves and stems. One of the high- lights in the study of biology, although some of the female students may argue this point, was the dissection of a frog. If done correctly, this promoted a better understanding of the organs of the human body and their functions. Chemistry, or the study of composition of matter, was offered to senior and junior stu- dents. ln the course of the year students learned the answer to many common mys- teries such as what happens when wood burns, why a cake rises and the principles of bleach- ing. Two days each week were used for lab- oratory experiments. Students quickly learned the importance of precision and exact meas- urements. lt was obvious to the student body of East that laboratory experiments were tak- ing place when vile odors penetrated all parts of the building. ln the physics classes students studied the causes and effects of everyday happenings. With the aid of classroom demonstrations, teachers explained the wonders of light and sound, why we see color and what happens when a radio is turned on. Astronomy, geology and radio are one- semester courses and are considered non- laboratory classes. They covered more specific fields such as the structure of the earth's sur- face, the stars and planets and the principles of radio. Classroom demonstrations comprise a large part of science courses. Here, Mr. Dominic Zorlengo explains to his Physics 2 class the principles of. re- flection. Using a concave mirror, he shows how his image appears upside- down. 21

Needless to say, this caused much confusion and anxiety among the students.

ZARLENGO Physics As a preventative measure, Mr. Jack Mclntosh demonstrates the correct way to handle acids. He explains to two of his chemistry students the dangers of spilling this acid on skin or clothing. Fortunately, few accidents happen in the chemistry labs, but it pays to be prepared just in case.
