This study analyze the trend and creativity of entry in chemistry sector of National Science Exhibition. For this study, award-winning entry in chemistry sector of National Science Exhibition during the last five years (2009-2013) were analyzed. The inquiry subject were classified six different items. The creativity evaluation rating of each entry was decided by a survey of the evaluator groups; teachers who participated in the training, winners' teacher. The results turned out as follows: First, In case of trying to choose inquiry subject of entry, it would be better for teacher to guide student into choosing everyday life or natural phenomenon in elementary school level, everyday life or academic area in middle school level, academic area in high school. Second, there was no correlation of creativity rating and actual award rating. Therefore, teacher will need to guide students' research synthetically in a variety of research areas.

The purpose of this study is to analyze the field of Earth science at a science fair. For this purpose, 566 pieces of data spanning 21 years (2000 to 2020), acquired from entries in the Earth Science section on the science fair website, were analyzed using the semantic network method. As a result, geoscience topics have been actively explored in works submitted for the Earth Science section of the science fair. Fossils from the Cretaceous period of the Mesozoic Era were particularly predominant. Together with these, keywords corresponding to astronomy, space science, and atmospheric science formed a small-scale network. Astronomy and space science mainly dealt with the dynamic characteristics of asteroids, Venus, and Jupiter. Other subjects included the solar system, sunspots, and lunar phases. Atmospheric science has focused on atmospheric physics, atmospheric observation and analysis technology, atmospheric dynamics, air quality monitoring, while marine science has been limited to physical oceanography and geologic oceanography. This study, is expected to help select Earth Science topics and conduct inquiry activities in schools.
