Science Classes g iology classes study everything from tree leaves to protozoa or one-celled animals. Every other day is spent in the laboratory where hairs and celery strings are magnified many times their orig- inal size to show their complexi- ties. Often the work deals with dissecting frogs or fish which illus- trates how similar they are to hu- mans. Pupils learn to distinguish between the different species of seaweed and other minute plants. The different types of bacteria are also explained to the students and they are taught which are harm- ful, and which are of some help. Chemistry is the class of ex- periments. What is an acid? MRS. FREDA PARMALEE, Edward Brigham, and Leonard Redd examine a snake wiggling on the driftwood. JOSEPH FOOS and Chester Henry unwrap new parts for the very delicate balance. 16 TOM HASSETT POINTS OUT the cells of the leaf to Carol Richards, Nina Dodge, and Bill Link.

Fundamentals Help Prepare for Emergencies POINTING OUT to his closs a picture of the muscles and nerves of the human body is Robert Leach. MISS BUNCE, also a security education and physiology teacher, finds time in her busy schedule to confer with one of her counselees. ecurity education is compulsory for every tenth grade student en- rolled in the driver training course. The class is divided into three periods of six weeks each. Students study the bones of the body and learn the main arteries that lead to the heart, and pupils take turns demonstrating the new method of artificial respira- tion. Another section is devoted to civil defense where proper proced- ures are taught in preparing for atomic attacks and other disasters. The third section is devoted to the trials and tribulations of dating: Teen- agers discuss their problems and the class offers solutions from their own experience. DEAN LUDWIG explains to a student the misfortunes of a dope addict. 15

Prove New Ideas What is a base? Test this com- pound with red litmus paper. If it turns red you will have found the answer. Such is the language of the chemists. Many basics have to be learned, though, before ever entering the laboratory. There is a special way to hold the stopper of a bottle, and test tubes have to be perfectly clean in order to insure a successful experiment. The modern equipment in the physics lab enables the classes to study the effects of the produc- tion of electricity by friction accu- rately. This year there is an in- tensive physics class for those who are able to interpret the laws quickly and thoroughly. The modern science students perform assorted experiments sim- ilar to those of the biology or chemistry classes. INTERESTED PHYSICS STUDENTS watch to see what will happen when the electricity is turned on. E. R. JONES and Homer Parker intently watch Varnard Gay as he tests the temperature of the solution in the beaker. 17 ELMER GALLEY, Robert Shaw, and Ward Walworth attempt to work out a difficult problem with the aid of a slide rule.
