Van Prooyen was finishing his time with the National Guard. Biology gave students a basic understanding of their environment, how it works, and how they fit into it. The chemistry class concentrated on studying chemical bonds, moles, and composition of mole- cules. They used the revised edition of their previous book, Chemistry: Exper- iments and Principles. The physical science course was again offered for the less scientifically minded student to fulfill the two-year science require- mentg it included the study of mechani- cal and electrical energy. The advanced science course, offered to juniors and seniors, studied aspects of biology in much greater detail, dissecting a pig and viewing micro-organisms. The last nine weeks of the class were devoted to individual study on selected topics.

Students Tackle lVlath Concepts The freshman algebra classes studied generalized arithmetic by solving daily equations. The sophomore classes stressed non-Euclidean geometry, an area of math based on different as- sumptions rather than facts. Third year algebra included an in-depth study of irrational numbers and introduction to trigonometry. Special areas of instruc- tion included the modular system and truth tables, Nlath I was a mixture of algebra, geometry, and arithmetic. which taught the practical use of credit and insurance. The advanced math class began the year with a nine-week trigonometry section. Other topics studied were concepts of calculus and mathematical induction.

Chuckling over their squishy frogs, the sophomores dig in once more to cut out the heart. Joining the science department second semes- ter, Mr. Van Prooyen continued to whip up en- thusiasm for plant life, parasites, and bugs. Advanced science students, Larry Heslinga and Jim Vroam find that drawing pictures of microscopic organisms is not so hard, provided you can see them, w 2 5
