On February 16, 1998, we invited Dr. Jan Davis and Colonel Mark Lee, two of NASA's astronauts, to our school. We had a chance to receive a lesson. It was very interesting to meet real astronauts, who are also real astronomers. Mr. Agata had the 120 students in the class complete a questionnaire before and after the lecture. This paper describes the student's impressions. As a result of this investigation, we understand that real experience has a good effect.
