Competing openly in the severe situation of corona

National tournament held for the first time in XNUMX years! XNUMX entries from XNUMX schools

Science Koshien aims to provide a place where science-loving students from all over the country can gather, compete, and play an active role, broaden the base of science-loving students, and develop their abilities.This year's competition received XNUMX entries from XNUMX schools.

At the opening ceremony, the representative schools were introduced, and each school appealed to the team as they wished, and finally showed the decided pose.On the first day of the competition, a written competition was held to compete for knowledge about science and its applied skills, and on the second day, a practical competition was held. On the final day, an award ceremony and a press conference for the winning school were held.

The "11th Science Koshien National Convention" is scheduled to be held in Tsukuba City, Ibaraki Prefecture in late March, XNUMXth year of Reiwa.

Challenge integrated problems that transcend the framework of written subjects and subjects

The written competition was held by selecting 12 athletes from each team.The competition time is XNUMX minutes.We challenged a total of XNUMX questions, including integrated problems that transcend the framework of subjects and subjects, with problems that can be solved by utilizing the knowledge acquired from science, mathematics, and information.

In the second question, golf, a cross-sectional view from the position of the golf ball to the cup is shown (the terrain is a mountain shape consisting of a flat slope), and when the golf ball and the cup are on the same horizontal plane (the size of the golf ball). The condition that the golf ball stays on the slope and the initial speed of the ball when hitting the golf ball with a putter is expressed by the head speed, and until the peak of the mountain shape is reached. It was a field-integrated problem of mathematics and physics, such as asking the equation of motion of a ball. [Explanation at the bottom of the page]

Athletes challenged difficult problems by demonstrating teamwork by members from different fields of expertise for problems that transcended the boundaries of subjects and subjects.In the written competition, Shibuya Education Academy Makuhari High School (Chiba Prefecture) gave the highest score and won the XNUMXst Kao Award.

Practical skill ① Challenge-18 Solve problems with programming!

"Charlenge-18" (10 athletes, competition time XNUMX minutes) is a competition in which two competition PCs are distributed to each team, and the PCs log in to the competition-specific site to solve information-related problems.The problem is XNUMX of [prime number] [Takuchi function] [binary system] [sequence of numbers with sum] [divisor] [partial character string] [integer] [doremi code] [character string operation] [sequence operation] It consists of categories, and in order to solve these, not only knowledge but also calculations are required.Calculations are not limited to manual calculations, but programming on a PC is required so that calculation results can be obtained efficiently.It is intended to make you feel the usefulness of problem solving by programming.

This time, Komaba High School attached to Tsukuba University (Tokyo) and Asahigaoka High School attached to Aichi Prefecture answered all the questions correctly, but the method of determining the ranking according to the answering time of a specific question is incorporated, and Komaba High School attached to Tsukuba University is ranked first. I did.

Practical skill ② Uncover the true identity of X! Estimating the structural formula of organic acid X in three experiments

"Uncover the identity of X! -Diping of ascorbic acid and organic acid X-" (XNUMX athletes, competition time XNUMX minutes) is a given white powder (compound of ascorbic acid and organic acid X) with XNUMX types of experiments. To determine the mixing ratio of ascorbic acid and organic acid X, and to estimate the structural formula of organic acid X.In scoring, experimental procedures, experimental results, considerations, etc. are also asked, so there are complex factors such as making a sufficient experimental plan, high and accurate experimental technology, abundant knowledge and thinking ability, creativity, teamwork, etc. I was asked. [Explanation at the bottom of the page] Hokkaido Asahikawa Higashi High School, which won the highest score, won the Asahi Kasei Award.

Practical skill ③ Shuttle windcar Proceed with the wind created by yourself!

The pre-released practical competition "Shuttle Windcar-Full Concentration! Science Breathing-Turning Headwinds" (60 athletes, competition time XNUMX minutes) uses prepared parts, materials and tools. Then, within XNUMX minutes, we made a shuttle windcar that uses only the wind coming out of the mechanism (blower mechanism) that attaches the fan to the motor as the propulsion force, and between the start / goal area and the return area of ​​the prescribed course, We will make a round trip with and without luggage, and compete for the time taken for the two round trips from the start to the goal and the weight of the luggage at the goal.

Since the blower mechanism is fixed to the wind car, it is necessary to run the course on a straight line without changing the direction, so a reversing mechanism that reverses the traveling direction is required.Since it was open to the public in advance, each team was ready to go, but after XNUMX pm, there was a happening that the second attempt was canceled due to the impact of an earthquake with a seismic intensity of XNUMX or higher in Miyagi prefecture.

The XNUMX teams that got the perfect score in the first attempt were ranked XNUMXst, and by lottery, Gunma Prefectural Maebashi High School won the Azilent Technology Award, Eiko Gakuen High School (Kanagawa Prefecture) won the Narika Award, and Kyoto Prefectural Rakuhoku High School won the overall championship. Five schools, Toyama Prefectural Toyama Chubu High School, Aiko High School (Ehime Prefecture), Tosa High School (Kochi Prefecture), and Miyazaki Prefectural Miyazaki Nishi High School, received the Excellence Award.
