'fYYTTYYYYN?ifTYYffTYY Science as a Form of Entertainment Science! Ah, that word reminds us of Room 45, the science room of McKinley. In it are eight large tables to perform experiments on. lt surely is a well-equipped laboratory, for there is enough equip- ment, such as bunsen burners, flasks, beakers, ring-stands, etc., for thirty-two students to work independently. And it is much more pleasure to do the experiments yourself than to watch others do them. Pictures which accompany this article show some of the experi- ments in progress. In one of them we see Helen and Hilda perform- ing an experiment which shows the effect of heat upon water. After filling a flash with colored water, a rubber stopper and a long glass tube were inserted. This is to see how far the water rises. After the flash was prepared, it was placed over a bunsen burner. When the water began to heat, it rose in the tube, which was caused by the molecules being disturbed. These molecules are constantly moving about in the flask, hitting one another, making them take up more space. Although there is more volume, it weighs no more. ln another picture we see Oscar and Ervin, who have just con- structed a crude thermometer to observe the effect of heat and cold on mercury. Another picture illustrates what is known as osmosis, or the passing of a liquid passing through the egg shell. Another shows the interest of other pupils in the study of plant life. If more students of McKinley knew the pleasure derived from science, we know that the new science room which is to be equipped in the new building would not hold all the pupils who would elect to study the subiect, for the things o-ne learns are interesting not onlv at school, but at home and wherever one meets the things we deal with in everyday life.-Helen Graham, Hilda Marsman, Oscar Sokol, Ervin Frauenhoff. Art and Future Artists The art classes have had many interesting problems this year, and the instructors have hopes of many good artists. There have been classes in designing, freehand drawing, water color work, and perspective art. They have made lampshades that were very artis- tic, and which were made from parchment paper purchased in China- town. Some of these classes had charge of the small trinkets for Y 1 ll1LLLllLLLLLLLLf1 -Ll

Other classes have been interested in freehand lettering, and have made many posters to advertise the plays and other happenings of our school life. Not the least interesting work of the pupils in the art classes has been the work on the stage sets for the many plays which have been given during the school year.

While, of course, the wood work for all this was made in the shops, the designs were made by the pupils in the art classes. That the pupils enjoy expressing their ideas in drawing may be illustrated by the response which was made to the call for cartoons to show the danger of hopping rides from passing automobiles. These were drawn without instruction and were wholly voluntary on the part of the pupils entering the contest. Among the many car- toons which were entered, that of Everett Wantland won first prize. The work done by the pupils for the Purple and Gold needs no comment. lt speaks for itself. Credit is given for this on other pages.-Leona Kitchen, A9. s Y L I illllllxgllllllillll L I
