The objectives of this study were to examine an interdisciplinary and experiential approach to environmental education by use of a youth gardening program for third through fifth grade students. In addition, this study evaluated the gardening program's effectiveness on promoting positive environmental attitudes and a high environmental locus of control with children. A questionnaire was developed from three existing instruments and was used to collect information concerning environmental attitudes, locus of control as it related to environmental actions, and demographic information of respondents. No statistically significant differences were found on either variable in comparisons of experimental and control group responses. However, students from both groups exhibited positive environmental attitudes. Demographic comparisons indicated that children with previous gardening experience scored significantly higher on the environmental attitude and environmental locus of control statements when compared with children without gardening experience. Girls scored significantly higher than boys on environmental attitude and environmental locus of control scores. Caucasians scored significantly higher when compared with African-Americans and Hispanics on environmental attitude scores, and Caucasians scored significantly higher when compared with African-Americans on environmental locus of control scores.
