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

Earphones Vibrate in Lab as Mr. Rosinski Sneezes Browsing through booths displaying features from different countries, sampling foreign foods, and watching a program were all a part of an exciting day for language students. The Internation- al Festival in November was held at the St. Paul Auditorium. Conversations, props for skits, commercials, speeches, book re- ports - all were typical aspects of study in the language classes. Magazines, movies, and film strips provided visual aids. Spanish students listened to a speaker from the Peace Corps who discussed his experiences as a worker in South America. A panel of students from the University of Minnesota talked about the transi- tion from high school to college Spanish. French IV students traveled to Northrup Auditorium to see French performer, Marcelle Marceau. Along with German and Spanish students, French students attended the Foreign Language Festival at Harding High School on April 20. ln February the new language lab opened for student use. It was a great improvement for the school system according to Miss Golberg. Thirty-two booths gave students the opportunity to hear and evaluate their speaking ability. Testing the new language lab, Sophomore .lean Miesbauer inter- prets a story from her German ll book. A fourth hour Spanish II class cheers Jerre Johnson on as she takes a giant swing at a pinata snow- man which she and Julie Groat made for a Christmas fiesta.
