We carried out this project because we were interested in the unification and we thouhgt the title of 'peace' was suitable for the unification. Just in time, there was Hangyere high school at our city An-sung that students who came from North Korea attend. And this school set up a sisterhood relatrionship with our school. First, we created posters that are associated with unification and promoted them to increase the attention about peaceful unification. Also we made unification bookmarks by hand and distributed them to our school's students and teachers. To expand our activity, we cooperated with the unification club named Dreaming of U.K and the chemistry club. Every lunch time, the chemistry club performed an experiential activity that marks a hand sanitizer. Through it, we earned profits and delivered all of them to the reunification organization. Hangyere high shcool also engaged in our activity. They worked on positive lines as starting a campaign about reunification at school gate. For about two weeks, we made a surprising result and students and teachers started to get interested in unification. We felt successful about that change and particiapted in our activities pleasantly. Even if this doesn't contribute directly to unification, throughout that activity, we thought deeply about the reunification pf north and south and got a wish into our head that such project will be more popularized.
