The opportunity for visiting science research institutions as part of the learning experience in elementary, junior high and high schools has been increasing in recent years. Although the requests for field study trips to science research institutions are becoming stronger, the research institutions are not social educational facilities but to do the latest science study. However, as the exhibits are related with the latest science research, students' understanding through the field study tour will depend on the knowledge they have already learned and their interest. Then, it would be important to make students' knowledge even to some extent before going to researchers' guiding tour. In this study, RFCode Spider IIIA, an active type RFID, Radio Frequency IDentification, tag system, was used to identify for many students at a place.
