The purpose of this study is to develop a horizontal balance for visually-handicapped elementary students. According to elementary 4th-grade curriculum of the current 7th science subject, the experiment with a horizontal balance re?ects putting some pieces of wood on a board (on the balances) and observing the inclination degree; thus, generally, it is available to normal elementary students only. This experiment is di?cult for those without sight, who rely mainly on the senses of touch and hearing to perform and analyze an experiment. Thus, in order to solve this problem, we put some sound devices on the experimental apparatus. This experiment, using the horizontal balance we had made, was conducted with those who had low vision and achromatopsia. To test the excellence and independency in the experiment, we chose Busan School of the Blind; and only then, we chose only seven students with a simple visual handicap from among students in the 3th to 6th grades for the experiment and counseling. We obtained educationally satisfactory results through this experiment.
