Encouraging students to become better stewards of the environment and to be more educated in science content knowledge is an important goal of today's educational leaders. Eight lessons were created to aid an established stewardship program (Coastal Roots) in introducing hands-on activities to middle school children in southern Louisiana. Students were tested on science content in the lessons using a pre-test, eight multiple choice quizzes (each focusing on a particular lesson), and a post-test. The “children's attitudes toward the environment scale” test was administered to evaluate environmental awareness changes in the treatment and control group students. Students who received the horticulture lessons improved their post-test scores by 11.4 points (P ≤ 0.05) in the first year and 25.07 points (P ≤ 0.0001) in the second year of the study. Significant increases in individual lessons were found both years. In the second year, students who received the lessons were more aware of their role in the environment than those who did not receive the additional lessons (P ≤ 0.01). The addition of horticulture lessons to the middle school curriculum enhanced student knowledge and stewardship of the environment.
