In this paper we describe the method on how to teach cultivation and metal working in industrial art course. Cultivation of flowers and vegetables is recommended in order to bring up a man who knows natural life and has feeling for nature. We submit some examples of cultivation, flowers and vegetables, which can be easily cultivated in industrial art course, as teaching materials. It is also necessary to rear a man who takes good care of things and has a allowance of some latitude in his thinking while he knows the real taste and charm of making a work in metal. A collapsible wind breaker with galvanized iron sheet for a portable cooking stove used in the field was manufactured by way of trial as teaching material of metal working. Machinability of mild steel and cast iron in a lathe was easily evaluated by method of measurement of wear loss of tool and classification in the shape of chips. Even beginners can readily understand machinability of metal materials in this method.
