   We won the Prefectural Governor's Award at the Japan Student Science Award Ehime Prefecture Competition and participated in the central final examination! December 17, 2023, 19:00 Kojo Research Institute, a third-year science and mathematics student, submitted an item to the Japan Student Science Award. However, at the Ehime Prefectural Tournament, he won the Prefectural Governor's Award and was selected to participate in the  central Tournament. In addition, I was selected as a representative at the central preliminary examination (document examination) held on November 12th, and participated in the central final examination (remote) held on the 17th. For the central final examination, participants were required to submit in advance a video summarizing their enormous research results into a 5-minute presentation with about 10 slides, and after the regular examination, they had to work hard to prepare the video while preparing for the personal exam. The question-and-answer session on the 17th required a lot of patience, as rigorous answers were required regarding the investigation of previous research, the validity of the model in model experiments, understanding of theoretical formulas, and comparisons with experimental values. However, we were able to somehow answer the question based on our experimental experience and knowledge. One of the students who participated said, ``Although it was a very tough question and answer session with lots of tough questions, I was happy that they asked questions after fully understanding our research, and it was a fun time.'' I got it. This marks the end of this research group's research activities. Although this is a difficult time, I hope that you will do your best to realize your career path.

The Kojo research group was awarded the first prize in the central final screening of the Japan Student Science Award.

   Project Research As a result of the central final screening of the Japan Student Science Award, the Kojo research group was awarded the first prize. I will not forget what I learned this time and will continue to improve my skills in the future.

   In a cooperative class between Ehime University and our high school,  first- and second-year students from the science and mathematics department attended lectures and laboratory tours.

   Lecturer: Dr. Yuko Kamika (Associate Professor, Department of Food Production Science, Graduate School of Agriculture, Ehime University)

Content:

(1) Observing the sorting of tomatoes harvested at a plant factory

(2) Collecting data sorted by a sorting machine

(3) Significant difference test using individual weight data (lecture and exercise at the Media Hall of the Center for Information Technology)

   First, we visited a solar-powered plant factory. Tomatoes were grown in a tall plant factory with glass walls, different from ordinary plastic greenhouses. The tomatoes were planted not in the soil but rather in rock wool and hung from above, making it look more like a "factory"  than a "field”. By controlling the plants’ growing environment, they are able to supply farm products at stable prices and quality throughout the year.

   Next, we also observed the sorting of harvested tomatoes by weight.

   After the tour, the students moved to the Information Media Center, where they had a lecture on significance tests while doing exercises using spreadsheet software.

   I believe that the methods we learned for data processing will be valuable for our future research.  ( 209 Ochi Kotaro, Sueda Yuito ) )

   On November 12, two third-year students of the school's Science and Mathematics Department participated in the presentation and award ceremony of the Botchan Science Award at the Tokyo University of Science.  It was a presentation of five outstanding research studies selected from among 221 papers, with 10-minute presentation presentations and a question-and-answer session with the university professors.  The presentation was the culmination of three years of work.  We have shown the possibility of reducing the disadvantages of wind power generation with the flywheel we have invented.  Unfortunately, we did not win the Grand Prize, but the judges gave us high marks, saying that our presentation was very good and that our research was highly complete.

   In addition to this, we received comments such as, "We would like to know what issues would arise if we increase the size of the power generation equipment.

   The competition was such that I would like to make the most of this experience in my future activities at the university I am going to attend.

   Received the Ehime Prefecture High School Education Research Association Science Department Chairman's Award (biology field) at the Fun Science Contest

   The final round of the Fun Science Contest was held at Ehime University on November 11. One team from our school participated in this contest, in which teams had to solve difficult problems in the six fields of mathematics, physics, chemistry, biology, geology, and ICT.  As a result of the judging, our team won the Ehime Prefecture High School Education Research Association Science Club President's Award in the biology field.

   In this contest, all eight of us were able to work out what we had studied in our respective areas of expertise.  As a result, we received the prize in the biology field.  However, it was not just about winning or losing. ■

   It was a great opportunity to stimulate our intellectual curiosity and motivation through cooperation with our peers and competition with other schools.  It was a day that made us want to deepen my knowledge and experience in the future. ( 209  Takaoka Ryuto, Kuromitsu Eita )
