l l Page 28 THE GENERAL SCIENCE INSTRUCTOR, Mr. Fink, explains how carbon dioxide gas is released from a tire extinguisher with such great force. Observing this most interesting experiment are Connie Bass, Dillard Brown, and Hugh Hagel. THE HYPOTENUSE OF a riqht triangle equals the surn of the square of the other two sides. Miss Giles listens intently to see that Marilyn Nelson's explanation ot the solid geometry prob- lem is correct.

and Language Arts Provide Culture Mingled voices are heard from the French class as stu- dents conjugate regular and irregular verbs. The French students are intrigued by the splendor ot Louis XlV, the rise and tall of Napoleon, and the historical monuments which torm the history of France. Pronouncing the gutteral sounds ot the German words is ot major importance tor students taking German. Part ot their daily assignment is to translate their Weekly news- paper, The Monastpostn. The history ot ancient Rome is brought to lite in the many Latin classes. Enacting famous plays and studying mythological characters set students in the right atmos- phere. Students also learn that the derivations of many of our English words come from Latin. The choral groups ot Peoria High School entertain stu- dents and adults by singing -a Wide variety of songs. The glee clubs are an introduction to the Boys' Choir, Girls' Choir, and the A Cappella Choir. The A Cappella Choir, consisting ot juniors and seniors, visits other schools in the area by interchanging with their choir groups. The Girls' Light Opera group specializes in singing songs from Broadway musicals. These classes iorm the culture ot Peoria High School. THE BOW MUST be held in the correct position in order to produce the desired sounds. Mr, Szepessy instructs Cindi Bach on the correct usage of her instrument. Orchestra is a class open to students having musical talent and Wishing to express this talent by playing with other students. MISS STEPAlTlS PEOUDLY shows her souvenir purse, obtained from a recent trip to South America, to several of her Spanish students. First hand information concerning the culture and people of the Latin American countries are given to the Spanish class. Listening to her experiences are Enrique Gutierrez, Alfonso Guerra, and Terry Thompson. Page 27

Math and Science Require Apt Thinking The smell of burning sulphur yielding sulphur dioxide and the ticking of geiger counters detecting the slightest trace of radio- activity are characteristic of the chemistry laboratory. This year atomic energy is being stressed because of its importance. Weighing crucibles containing unknowns is one of the steps taken by chemistry students to complete their study of quantitative analysis. Qualita- tive analysis, included also, requires the find- ing of an unknown by titration. After carefully dissecting their well-preserved frogs, biology students probe into the anatomy of this animal hoping to learn more about its circulatory, breathing, and organic system. Their efforts will be rewarded when students who successfully remove their frog brains receive the honorary Doctor of Progology. Annual tree trips are taken to enable students to recognize and learn the names of the various species of trees, shrubs, and plants. First year algebra students struggle through the formulas and equations which must be ul solved. The letters X and y are substituted for numbers in these equations. Application of basic principles prove a necessity. More complex problems are considered in third year algebra. Students are faced with complicated equations which must be plotted on graphs. instead of working equations to find the solution, this process is reversed to making equations from the given solution. College algebra, an extension of third year algebra, is offered to students who wish to enlarge their algebraic knowledge. This course is on a higher level acquainting stu- dents with college-level work. Proving triangles equal to each other by certain formulas is not an easy task. Plane geometry students discover this when they solve the theorum of Pythagorus. Plane sur- faces are constructed and studied in plane geometry. Sines, cosines, and tangents are common terms used in trigonometry. Right and oblique triangles are solved by the students.
