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 ' .
