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.

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.

Vocations Lay Sewing machines whir constantly in the clothing room where girls learn the fundamentals of clothing construction. The study of wardrobe planning, color analysis, and dress design are included in the cur- riculum. Products of the girls' talents are the skirts, vests, suits, and dresses made by first and second year students. The management of a home includes decorating and planning it so that it will be both attractive and comfortable. Home management students keep these important facts in mind by drawing plans and by gathering pictures of well-decorated homes. Topics brought into the discussion of the family living class are the care and support of a family and the responsibilities involved in family life. Both boys and girls enjoy this course because it will eventually pertain to their own lives. For boys who wish to become architects and engi- neers, tee-squares and drawing boards, familiar objects in the mechanical drawing class, are a must. GUTTERS NEED a coat of paint also, as Bill Beaty and lohn Cassulo dis- cover in their house building project. Every other year the building trades class starts to build a house which will be completed the following year.
