The history classes in the lower grades use sand-tables to reproduce the topography of the localities which are being studied, or to describe the progress of some battle or invasion. One of the pupils in 1912 constructed with his own hands in the wood-working shops a miniature Roman temple about five feet in length, the plans of which he had worked out from the descriptions in the histories. These classes often engage in debates, and the written reports which are sufficiently interesting are read in “auditorium,” and often printed in the local newspapers. Bulletin boards are placed in the hall for displaying important clippings. The pupils bring these, and classify them under the headings,—foreign news, American news, state, city, and county news, pictures and cartoons, and items on the special topics that are being studied. The history classes have charge of a small historical museum in the corridors, which contains a loan collection of Indian relics and of pottery from Central America.

The teaching of science occupies a unique place in the Gary schools. Just as the history and geography are taught as clues to the social and political world around the pupil, so the science is used to acclimatize him to the natural world. The theory is that children should commence the study of the sciences while their minds are still plastic and their interest in natural phenomena keen. The persistent questions which the child asks are attempts to get an understanding of the world he lives in. Unless these questions are answered, his interest is apt to wane as he grows older. And unless he acquires a familiarity with nature that is accompanied by true scientific information, he is apt to get only a satisfied feeling of knowledge without any true appreciation.

Science in the Gary schools, consequently, goes beyond the simple nature-study taught now in most elementary schools. The child has experience with the laboratory at an early age. The smaller children from the third, fourth, fifth, or sixth grades go into the chemistry, physics, botany, and zoölogy laboratories as “helpers” or “observers” to the work of the high-school classes. On the theory that “children are natural scientists” they are allowed contact with apparatus and materials. It is said, in fact, that experience shows the smaller children to be as careful as the older, and actually to cause less breakage and damage.

The science classes in the lower grades are taught neither in formal recitation nor in formal laboratory work, but in a combination which the instructors describe as “experience meetings.” Pupils and teacher meet on common ground to exchange ideas about their experiences in dealing with natural phenomena. The outside world is treated as a great laboratory, and these “experience meetings” are used to interpret the children’s experiences in terms of scientific principles. There are demonstrations by the children, assisted by the teacher; a little individual laboratory work; and considerable vocal reading from textbooks and scientific story-books.

The Gary science instructors believe that much time and money have been wasted in the teaching of science in high schools, owing to the elaborate methods which have treated the students as if the purpose was to make professional scientists of them all. Children, it is believed in Gary, cannot resort to the detailed research methods of scientists, but must have quick answers and quick results. There is a waste of energy in trying to duplicate in the laboratory the fundamental experiences of life which the children are constantly seeing outside in the great laboratory of nature.

The care of the flowers and plants and gardens, the care of the animals in the zoo, and the study of their habits offer endless concrete material for building up the theoretical side of botany and zoölogy. The pupils are trained to observe and to write down what they see. One class in zoölogy last year made an illustrated booklet descriptive of the school zoo. The text was written by the pupils, the photographs prepared by them, and then the booklet was tastefully printed in the school printing-shop by the pupils themselves. The result was a charming brochure, in which not only the pupils themselves, but the whole school could take pride and pleasure. Such scientific study becomes an intimate and vital part of the entire school life.

For the physics classes, the lighting, heating, and ventilating systems of the school afford a practical textbook. In the Jefferson School, where the industrial shop is built around the boiler-room, the heating plant becomes an integral part of the shop. The physics classes study the climate and the weather. They study particularly the principles of the machines used in the different shops. Each shop may thus act as an extension of the physics laboratory. Classes of even the smaller children are sent to take apart machines like the bicycle, cream-separator, lawn-mower, and explain the construction. The automobile and motor-cycle provide many practical lessons. An old automobile which needs tinkering up is considered in the Gary school to be almost a physics laboratory in itself. The writer witnessed a physics class of twelve-year-old girls who, with their nine-year-old “helpers,” were studying the motor-cycle. With that disregard for boundaries which characterizes all Gary education, the hour began with a spelling-lesson. The names of the parts and processes of the machine were rehearsed orally and then written. After the words were learned, the parts of the machine were explained by the instructor while the class spelled the words over again. Their memory of certain physical principles, such as vaporization, evaporation, were called again into play. Then the instructor set the motor-cycle going, the girls again describing its action. When this had been thoroughly gone over, the class copied from the blackboard sentences describing the processes and parts, but omitting certain crucial words which the pupil had to supply. The intense vivacity and interest of the little group, the intelligence with which these small children grasped the principles involved, made the lesson seem a model of expert teaching. It was an excellent illustration of the way concrete processes may be used to build up scientific knowledge. It is interesting to notice that no distinction is made between boys and girls in their science work.

This lively interest in scientific processes may have unexpected results. The story is told of a high-school boy who, while the board of education was discussing means of fire-prevention, made an investigation of methods and processes which was so excellent that it was forthwith adopted by the board.

This incident is typical of the way in which the scientific work in the schools may correlate with the wider social community. Just as the history classes may bring the pupil into touch with the political life outside the school, so the physics and chemistry class may connect him with the industry of the community and with those public services into which scientific processes enter. A boy, for example, brings to the chemistry class a bag of low-grade iron ore which he has found in the vicinity. The class, under the direction of the teacher, constructs a simple electric furnace and reduces the ore. This experiment is then used as the basis for a study of the great steel industry upon which the city of Gary is founded.

A part of the chemistry work makes a direct contribution to the city. Gary has the good fortune, or the good sense, to have as chemistry teacher in the Emerson School the man who acts as municipal chemist for the city. As a result, the school laboratory becomes an extension of the municipal laboratory. The high-school chemistry pupils assist the chemist just as the smaller children assist them. With the chemist-instructor the pupils test the city water and the various milk supplies. Under the sanitary inspector they visit, as part of their “application” work, dairies, factories, bakeries, food-stores. Last year the class issued a “Milk Bulletin,” containing general information, with reports of their tests. The various articles were recorded as part of the English composition work, and the bulletin was printed by the pupils in the school printing-shop. In quality these bulletins seemed scarcely inferior to what an agricultural school might issue. On their inspection rounds, the class takes samples of sugars and candies from the various shops of the town, and tests them in the laboratory for purity and for the use of harmless coloring matter. Another class experiments with the soft drinks sold in the town, testing their composition, and studying physiological effects. The children are practically deputy food-inspectors, and make their reports on the official blanks. It is said that the result of this sort of inspection is that in a prosecution for violation of the pure-food laws in Gary a case has never been lost.
