In the present work, the experimental comparison for the following two process of teaching for "Action of Air" in the second grade of primary school is done. I In the case of the teaching process, "Action of Air" → "Existence ofAir" → "Weight of Air" (the ordinary teaching process in the many textbooks). II In the case of the teaching process, "Existence of Air" → "Action of Air" → "Weight of Air." From the results of the investi gations on the actual state of the recognition for "Air" of the children in the 1st~6th grades, the poorness of the recognition is clarified unexpectedly. In the view of this actual state of the recognition, the teaching process II is considered to more effective for the understanding and the grasping of "Action of Air" than the process I. Then, the superiority of the teaching process II is statistically confirmed.
