The solution to today's water pollution problem lies in every per- son 's kitchen sink, so says Mr. Brady to his biology class. In her algebra and trigonometry class, graphing functions puzzles Junior Vicki Hansen, so she receives pointers from Mr. Baldwin. LAB ASSISTANTS. FRONT ROW: Jean Eckman, Viv Jaruch, Sue Martinsen, Marcia Zurek. TOP ROW: Sue Sours, Mark Hughes, Dewey Kulzer, Mike Mihalow. Q M Classes Draw One Every Twelve Boys Physics Girl To Besides moving into a whole new area devoted strictly to mathe- matics, the math department added a new course, modern intro- ductory analysis. Over titty seniors studied induction, vectors, com- plex number fields and limits. Plane and solid geometry combined to torm one course. The iunior math course consisted of algebra and trigonometry. Newness was apparent in the science department also. A new biology section was added with two new rooms, Special plant and animal rooms kept livestock separate from the classrooms. Biology ll was formed and studied everything from drug addiction to water pollution. Students gave oral reports and debated such issues as the legalization ot drugs. An otticer trom the Minneapolis Police De- partment talked about alcoholism and demonstrated a breathilizer, used to determine the amount ot alcohol in the blood. Biology l stu- dents made leaf and insect collections, trained rats and worked with developing chick embryos in unborn eggs. 'W
