Rare amporhous solids, unique rock formations and theories of light, sound and mo- tion summon minds geared to scientific investigation. Physics explored base relation- ships through laboratory experiments concerning mechanics, heat, sound, light, and electricity. Inves- tigative lab sessions were spent examining relation- ships ranging from those between force and momen- tum to the density of a material and the refraction of light. Physics attracted students with a strong sense of science who enjoyed the vigorous mental gymnastics the course demanded. Chemistry students, armed with indispensable slide rules and periodic charts, tackled problems ranging from equations like H2 S04 +Zn -+ H21 ZnSo4 ,to the law of definite proportions. Lab sessions involved girls in specific investigations such as the production of oxygen through water displacement, and the determin- ing of the empirical formula of copper sulfide. As the year progressed, those once insurrmountable chemical bonds and structural formulas became second nature to the dedicated chemistry student. Students participating in earth science probed the 'natural world through investigative processes. Geol- ogy, astronomy, meteorology, and oceanography were divided into quarterly topics so that an in-depth and thorough study of each science could be pursued. Var- ied projects included the construction of manders, the charting of area weather conditions, and the study of the effects of erosion. Out of knowledge gained, came an awareness and appreciation of rnan's environment. if ' .

Physiology sweeps students into the complex yet fas- cinating world of the human body. Students earnestly explore structure and function of the body through the study of various body systems. A major accomplishment of the year was the mastering of the intricate parts of the human skele- ton. Biology combined laboratory investigation with knowledge gained from textbooks. Investigative pro- cesses included the study of plant and animal cell structures, the identification of different blood cells, and the regeneration of planaria-all accomplised with the aid of the microscope. Freshman, when not conditioning their bodies in gym were becoming aquainted with the ideas of health- ful living, a course which stressed that healthful living involves not only the physical aspect of the body, but also the mental and emotional health as well. Regardless of whether the science involved an inde- pth study of mitosis, the discovery of a blood type, or a general study of healthful living, each student met and overcame challenges encountered. l l My-1 -,'.
