Introduction : Many environmental threats are consequences of human behavior. The only solution for reducing the environmental problems is changing human behavior. Therefore, the aim of current study was to investigate the influence of environmental education group on environmental attitude and increasing environmental awareness among the female students in Tehran.

Method: The study is quasi-experimental with pre and post-test.  60 students were selected through multistage sampling method from female elementary schools in 2014-2015. They were assigned randomly to the control and experimental groups. The environmental education was conducted with experimental group during 10 sessions (90 minutes, twice per week). The research instrument was the children's attitudes toward the environment scale (CATES-PV) (Musser,1997). Statistical analysis was conducted using the analysis of covariance.

Results: The results indicated that there is a significant difference between the pretest and post-test scores in the experimental group in environmental attitude (F= 162.036, p= 0.001) and awareness (F= 174.000, p=0.001).

Conclusion: The findings emphasized that environmental education, which is proportional to age, plays a crucial role to enhance the environmental attitude and awareness. Hence, it could be considered as a preventing strategy to destroy the environment.
