Chem II students like Bob Hursh prepared solutions and necessary equipment for Chem I experiments. Intently measuring the temperature of water Marianne louzingor completes the experiment with success. There are atoms all around us; all things have energy; man lives in dynamic equilibrium with nature. These are the basics ideas from which evolve three major sciences—chemistry, physics, and biology. The opportunity for study in any of the fields was challenging enough to tax, and intriguing enough to satisfy the others. In the seventh, eighth, and ninth grades we studied general science which covered a variety of topics. The sophomores branched into biology, studying man and his relationship with his environment, ecology, and genetics. As juniors we could elect chemistry and study equilibrium in chemical reactions and random motion of molecules. Chem II was offered to seniors who showed a special interest. The physics students, primarily seniors, delved into the mysteries of energy, light, and optics. Science is a fascinating field because it directly involves us all. Our lives depend upon science—from the simple grade school experiments to the highly technical flights from Cape Kennedy. This doesn't mean that we depend upon the experiments themselves, but upon the concepts, ideas, and data gathered from these experiments. Mr. Ulander presented o demonstration of the intricacies of eclipsos. 13

The Relentless Exploration into the Known and Unknown The dilemmos of chemistry were dissolved by Mr. Von Wyk's crystol clear explanations. Mr. Linn tought General Science which takes in mony varied aspects of science. Pipetting his woy through the realm of biology, Mr. Peterson prepared on enlightening demonstration. 12

Mr. Samuelson combined his friendly attitudo oword students with his willingness to help them to produce an informal, enjoyable atmosphere in his math classes. So many of the things in our lives depend on numbers. Bridges, houses, roads, and cars are all built with the use of numbers. Ships and planes would be lost at sea if they had no means for finding their position. Mathematics, the science of the relationships of numbers, is taught at four levels—algebra, geometry, trigonometry, and Moth V. Algebra I and Algebra II are where some of us were first introduced to unknowns in functions and relationships and some of the advanced maths. Plane and solid geometry were concerned more with the theories of math than the actual mechanics of numbers. Theorems of plane and solid figures were proven so to make the solving of polygons. We worked with the triangle in trigonometry. We began with right triangles and finished with scalar and obtuse triangles finding solutions for the unknown angles and sides. Math V was available for those who cared to delve further into the workings and mechanisms of the world of numbers, and gave more background to those who planned to continue math in college. 14
