The purpose of this study is to closely examine the changes of food and drink waste amounts, and student's environmental literacy. By using creative methods, discretional activity classes, and programs to dispose of food and drink waste from students schoolmeals, and at the same time conduct and teach environmental education classes. To achieve this, students were given ten class lessons in creative discretional activities. Students were given flowerpots containing earthworms and were instructed to raise them, using food and drink waste from school meals. Four classes who were participating in project were examined for changes from March to July 2005. As a result the environmental education classes through creative discretional activities didn't have any significant influence on the students environmental literacy. However it did make a difference to the student's in-terms of their ecological knowledge. The project using earthworms to dispose of food and waste drink showed a decrease of 15% of the amount of waste food and drink from school meals. Moreover student's environmental literacy had been significantly influenced about environmental sensibility, value and causes. Through this study I found that the project using earthworms to dispose of waste food and drink, and creative discretional activities as a lesson decreased the amount of food and drink waste at the school, and the changes to students concerns and understanding about environmental sensibility, value and the various causes of waste food and drink.
