During a lecture. Mr Sheldon Johnson, with a wrv smile, wanders off on a tangent. Mr Harold Schmitke corrects his student’s drawings of what they have seen under their microscopes The Challenge of Tomorrow Causing reactions is a part of the chemical experiment performed by John Brimsek and Vince Novak

Mathematics is a science, a science of numbers. In high school, a student has a choice of many math courses; geometry, algebra, higher algebra, advanced mathematics, solid geometry and trigonometry. Axioms and postulates, 30°-60t triangles and parallel lines are all a part of geometry, the science of lines and angles. Variables, the rectangular coordinate system or square roots may be confusing unless one has had higher algebra. For that matter, they are often confusing to those who have had it. Advanced mathematics is a culmination of all previous math with more difficult problems added. The more advanced math students also take solid geometry and trigonometry. Checking daily assignments is part of Mr Warren Sims' job in higher algebra

1 .auric Riach and Diane Salo discover that experimentation demon- strates the basic concepts of physics. Asexual reproduction, valences and vectors. These words become familiar to all who study biology, chemistry and physics. Most sophomores take biology, learning such things as the formula of glucose, the experiments of La Voisicr, human reproduction and the Theory of Evolution. When the sophomores finish the year most of them know the definition of biology—the study of the growth and de- velopment of living things. Chemistry, the science dealing with the make-up of materials and what happens to the composition under certain circumstances, is tackled by either by juniors or seniors. Valences, chemical quations and the periodic table are studied and memorized. Experiments are per- formed; and example of learning by doing, giving the student a change to work out his own methods of obtaining answers Physics, an understanding for only the mathematically gifted, teaches scientific phenomena Here too, lab work is used to help the student better understand the how and why of physics; many students working out their own experiments. New at Roosevelt High this year. Mr. Charles Elving teaches the properties of the physical world Chemistry instructor. Mr. Phillip Kangas. explains the use of a balance scale. 23
