This study is to verify the effects of sensory education based on classroom activities for $2^{nd}$ and $3^{rd}$ grade children. The hypothesis is that children who participated in sensory education would demonstrate positive changes in eating behaviors through sensory experiences. The sensory education program consists of 12 lessons. Twenty-six children were being recruited from one school in Changwon, Korea. Two control groups, one of which was the same age as the educated group and the other group of sixth graders, were selected by random sampling from the same school. Children answered a self-administered questionnaire. The parents (n = 20) of the children who participated in the program, took part in evaluating the program through self-administered questionnaires after the program ended. The questionnaire contained variables of general characteristics, education satisfaction, nutrition knowledge, eating attitude and behavior concerning unfamiliar foods. The score of nutrition knowledge was improved in educated children (P < 0.05). Food neophobia score towards unfamiliar foods (P < 0.05) was increased in educated children, but there are no changes in eating behaviors in all groups towards unfamiliar foods. In conclusion, sensory education is useful for having a positive eating attitude among children. Its consistent implementation could lead to healthier and well-balanced eating behaviors for children.
