Nancy Jean Myers. Joy Wren, George Klein, and Delores Hungncss work on a hoat of vaporization experiment as Mr. Brenneman looks on. Why is the grass green? How do we breathe? What makes the wheels on our cars go around? How much oxygen is there in a glass of water? The science field is a vast one, offering many opportunities for further research. The courses at high school touch a few phases of this tre- mendous field. Animal lovers can enroll in Zoology. Those thinking of scientific professions can benefit from the Physiology, Chemistry, Physics, and Biology courses, dealing respectively in the structure of the human body, chemical state of matter, physical state of matter, and the study of both plants and animals. Earth Science pro- vides a good course for the future geologist. Miss Johns points out some of the distinguishing characteristics on one of her many mounted birds to one of her Zoology students. 16

 All right, now with chalk and string bisect angle A. These words, typical of any geometry class, sound rather formidable, but knowledge of fun- damental mathematics is practically essential. When charting his way in life, whatever his plan may be, the student must know much about mathematics. To help him obtain this knowledge, many courses in mathematics, both simple and specialized, are offered in Daven- port High School. As many as four semesters of Algebra are offered to those wanting to learn abstract rea- soning through use of letters representing num- bers and quantities. Trigonometry, Plane and Solid Geometry are offered for anyone desiring specialized instruction. Concerned with the science of magnitude and the properties of lines and angles of both surfaces and solids, these courses present a distinct challenge to the high school mathematician. A student must take a year of Sophomore Arithmetic if he fails to pass an entrance ex- amination. Higher Arithmetic, giving increased knowledge of numbers and figures, is the other course available. Before being graduated from high school, each boy and girl must pass a certain mathe- matics test or have a year's credit in one course in this field. Every Adult, whether a common worker or an executive, must have some knowledge of mathmatics to help construct a better world for himself and his neighbors. Mathematics instructors, left to right, arc Willis Rosing. Russell Bickford, and Jesse Day. At work on the snap Trigonometry probloms are Dick Meyer, John Storms. Coletto Von Ahnen. and Tom Pries Solid Geometry students in Mr. Day's class look ponder- as Mr. Bickford looks on. ingly at his demonstrations of the spherical triangle. 15

 imo ii i While his Biology class looks intontly on. Mr. Woodrofle demonstrates the workings oi the hu- man digestive system. In Biology such things as cell division, diges- tion of food, and circulation of the blood are touched upon, and then studied more com- pletely in Physiology. Experiments concerning vaporization, the pulley, and humidity are demonstrated in Physics class and then worked out by the students. Chemistry students spend two days a week in laboratory practice and the others in class recitation, discussion, and lecture sections as they study the evaluation of numerous form- ulas. Nurses' Chemistry is taught as a separate course from the college preparatory type. Earth Science, concerning different rock forma- tions and geography of the land, points out unusual formations like many found in the Mississippi River area. It is not only the future scientists that find valuable knowledge in these courses, for the average man needs much of what is discussed for everyday use. The natural scionce teachers. Milton B.
