ina! f W V...-an 4.-. 6 '-fx- ,fy Q!- ABOVE: Proving a higher algebra equation by dia- graming it on the squared blackboard is Barb Berry. Larry Gasner looks on and checks her progress from the steps shown in the Illinois Plan Boolc. RIGHT: Ge- ometry student, Mary Calhoun, manipulates the special blackboard protractor as she goes through the various preliminary steps in the bisecting of any angle. Science coupled with mathematics is the key to many professions. Students plan careers in science by taking biology, chemistry, and physics as well as al' gebra, higher algebra, plane, practical, and solid geometry, and trigonometry. Biology ohers knowledge in the area of plant and animal life, Chemistry students have the oppor- tunity to explore and apply chemical laws and theories in the laboratory. Physics develops funda- mental ideas of time, space, and matter. ln mathematics courses students advance from tre art of using formulas to extending the theories and methods of plane geometry to tnree dimen- sional hgures, Through these mediums students be- come better aualihed to enter the world either as a laborer or as a college student. Profound concentration is reflected on the face of physics student, Allan Rypka, as he puts into opera- tion a device which generated a current and registers the volt on a meter. This homemade contrivance is frequently used by physics classes in their study of and experimentation with the great form of energy, electricity.

Wordsworth may have found humanity sad and youth thoughtless, but Miss Drum has received happiness from both oi them. Biology becomes more meaningful through the insect and leaf collections which she helps us to gather by generous contributions of her time. Classes are often enlightened by hikes and early morning strolls, where we learn to study and appreciate cur world. Throughout her years of teaching Miss Drum has con- tributed much to her students' growth in the held of science. Although biology is her main activity she has also found the time to be Girl's League advisor, serv- ing her school honorably in this and many other assignments. earching Unknown Is Challenge of Man n BACTERIAL TOXINS ON LEFT: First place winner at the State Science Fair, Dean Rietz proudly explains his project to Tim Rowley who also attended this event. His display showing the efiects of bacterial toxins on chicken embryo required many hours of careful and painstaking work. 2 ' 8 1 .. -l 2- 3 RIGHT: Katrinka is an important part of every biology course. L. Quale replaces a section of the model's head as she, M. Granowski, Und R. Soukup, conclude their demonstrations for the class.
