Abstract
A science outreach program in currently-developing biotechnology for secondary school students, school teachers, and citizens was attempted for better science communication. For secondary school students, the textbooks were developed by scientists and school teachers in collaboration, and the actual classes were also operated under their cooperation. In school teacher training, the textbook and the experimental methods were devised to be available for classroom use without any modification. For citizens, simple and easy methods were adopted and performed at science cafe, so that the visitors can enjoy the excitement. It has been identified to be important for better science communication that scientists should understand the students', teachers', and citizen's situation and their levels of knowledge, and that collaboration of scientists and school teachers is extremely effective in classroom outreach.
