MAKING POSTERS FOR CHEMISTRY* E. E. RADEMACHER, No~omsTOWNSEIP HIGHSCHOOL, NOKOMS,ILLINOIS The merits of poster making as a means of arousing interest in a subject EDUCATION.** have been many times discussed in the JOURNAL OF CHEMICAL Our experience along this line is presented herewith for whatever value it may be to teachers interested in this type of project. The pupils of the general chemistry class undertook the task of making posters on the various elements. The subjects were not assigned but were selected by the pupils from a list of titles placed on the bulletin board. In some cases several chose to cooperate in preparing one poster. The material was collected by the individuals from numerous sources. The previous year the science club had collected from over one hundred fifty manufacturing concernst exhibit materials which included manufactured products from the cmde to the finished form, photographs, and literature of all k i d s . These materials formed the nucleus around which the posters were made. Local sources of pertinent materials were also exhausted. A "dummy poster" on ordinary paper was first submitted for approval. In this way the students profited by suggestions made regarding arrangement of material, lettering, drawings, pictures, etc. The final posters were made on beaver board of uniform size, two by three feet, with edges sanded, and the whole painted in a cream color and striped in dark green or black with a striping brush. Several regular laboratory periods were devoted to this work but a considerable portion of the work was done outside the regular class time. A unique feature of the whole project was the "poster party" held for all students working on posters. This included not only the twenty-four chemistry poster makers but in addition twenty-four biology poster makers. The evening was devoted to hammering, sawing, drawing, painting, lettering, stenciling, pasting, drilling, and typing-a typical factory scene. Refreshments were served. The success of this poster project is told by the ten selected posters reproduced on the following pages. Each point in these posters was illustrated by the real material, a picture, or a drawing and use of the same. Posters help the pupil who makes them, the teacher who uses them, and the general public who sees them.
