Water Quality Survey of Yamato River ( Osaka Municipal Shinkitajima Junior High School Science Club )

Water quality survey near the mouth of the Yamato River has been conducted continuously for more than 3 years. pH, COD, NH₄⁺NO.₃^–NO.₂^–and dissolved oxygen concentrations to determine seasonal and daily changes. Although some of the data has revealed some areas of relationship, there are many items for which the relationship is not yet known regarding change. Activities are being conducted under the guidance of the Yamato River Office, Suminoe Sewage Treatment Plant, and Wakayama University. Other activities include conducting water quality surveys upstream of the Yamato River and studying aquatic organisms. [/box] [box color="lgray"]

Let's go to Mars! ( Otemon Gakuin Otemae Junior High School )

Why are humans going to Mars? Is there life on Mars? To solve such questions, we will propose new methods of space exploration. During the presentation, we are considering a presentation format that visitors can enjoy and understand using Lego Mindstorms. We hope that this will be an opportunity to think together about the significance of Mars exploration. [/box] [box color="lgray"]

Body fluid circulation in tardigrades ( Kyoto Prefectural Kizu High School )

＜It is said that tardigrades do not have a circulatory system, but observation of body cavity spheres floating in body fluid seemed to be linked to the movement of their limbs. We also studied the muscular structure of the limb movements immediately before and after water absorption. When the limbs stopped moving, the body fluid stopped flowing. The tardigrades used piston movements of their limbs to circulate fluid stored in the limbs throughout the body. We speculate that the apparent walking motion of the tardigrade may be this piston movement, and that it is related to the circulation. [/box] [box color="lgray"]

Influence of Agricultural Activities on River Water Quality ( Kyoto Prefectural Kizu High School )

We decided to investigate how agriculture, which is supposed to form the landscape and climate of a region, affects the natural environment of the neighborhood from the viewpoint of river water quality. The study was conducted on tributaries flowing into the Kizu River in the area from Kizugawa City to Kasagi Town. Water samples were taken from near the center of the stream and analyzed. Drainage water from the tea garden of Kizu High School was analyzed as needed to investigate the actual situation of fertilizer runoff from the tea garden. Analysis of pesticides in river water was conducted by the Sudo Laboratory of the Faculty of Environmental Science at the University of Shiga Prefecture, and qualitative analysis was conducted by LCMS at the same university. Neonicotinoid pesticides were analyzed by LC/MS/MS at Hiyoshi Co. [/box] [box color="lgray"]

Observation of sea turtle spawning ( Kansai University Hokuyo Junior High School Science Club )

Since 2010, we have regularly visited Minabe-cho, Wakayama Prefecture, to observe sea turtles spawning. Last year, we visited in August, and although we were unable to observe the spawning, we were able to observe turtles hatching from their eggs and emerging from the sand. This year, we visited in mid-July, when spawning frequency is even higher, and succeeded in observing sea turtles laying eggs. In the presentation, we will present our observations of sea turtles laying eggs and interviews with volunteer staff working in the area, all in English. [/box] [box color="lgray"]

Aiming for the National Championship in CanSat Koshien ( Toin High School Science Club, Wakayama Prefectural Toin High School )

Our school has participated in a national competition called CanSat Koshien for seven consecutive years. This is a competition in which students build their own empty can-sized satellites, use them to acquire various measurement data, and process the data to draw conclusions. The winner of the competition is eligible to participate as an observer in the ARLISS competition held in the United States. Our school won the national championship in 2010, and our seniors went to the United States. We are now working on it during the summer vacation to win the competition again this year. The cansats will be transported by rocket to the sky and released from an altitude of 200 meters. I would like to introduce the CanSat project, which has been carried out for two years, to junior and senior high school students all over the country. [/box] [box color="lgray"]

Water quality survey of the Amano River ( Hirakata Municipal Sada Junior High School Science Club )

Since last year, we have been conducting a water quality survey of the Amano River, which flows through Hirakata City, with the support of the Japan Science and Technology Agency. In the Amano River and its tributary Shakuji River, we investigate changes in water quality by examining COD, ammonia nitrogen, phosphate phosphorus, etc. with pack tests and by examining environmental indicator organisms. One site is located in the Shakuji River. The results of the pack test showed that water quality deteriorates when the water temperature rises, and that in the Amano River, water quality is not necessarily poorer downstream than upstream. In this regard, the survey of environmental indicator organisms concluded that the further downstream you go, the worse the water quality is. [/box] [box color="lgray"]

Plankton and water quality survey in a protected pond for Nippon-baratanago (RE-1) ( Biology Club, Seikaze Junior High School )

The Biology Club of Seifu Junior High School is working to protect the Nippon baratanago, which is listed as an endangered species (Category IA). The Nippon baratanago has a special breeding method in which it lays its eggs in a freshwater bivalve called a dove shell. The dove mussel, which serves as a spawning bed, is parasitized by the fins of the leafhopper as a juvenile (glochidium), grows up, and then leaves the shell by itself, landing on the bottom of the shell. In other words, in order to protect the Nippon baratanago, it is necessary to protect the glochidium, which in turn requires the protection of the reef snails. For this reason, our school's biology club is engaged in activities to conserve not only the Nippon baratanago, but also the entire ecosystem, including the dobsonid mussels. We are interested in plankton, and have been conducting plankton surveys since 2013. [/box] [box color="lgray"]

PET Bottle Rocket: The Way to Represent Japan ( Ashiya International Secondary School Science Club )

Our school's science club has been working on a PET-bottle rocket, and in July we won the position of Japan's representative at a national competition hosted by JAXA. We continued our research every day until we won the position of Japan's representative. In my research on PET bottle rockets, I was exposed to air resistance and complex dynamics. I would like to present a summary of the physics hidden inside the PET bottle rocket. [/box] [box color="lgray"]

Finally discovered the nearly extinct Genji Firefly in Tondabayashi City! ( Osaka Prefectural Tondabayashi High School Science Club, Firefly Team )

Last year's survey revealed that genji botaru (fireflies) in Tondabayashi City are on the verge of extinction. In order to understand the reasons for their decline in detail, we investigated changes in water quality, sediment quality, and the habitat of river snails, which are important as larval habitats. In the 1970s, the water quality in Ishikawa was so polluted that the larvae could no longer be observed, and in the 1980s, the riverbank was revetted, which further deteriorated the larval habitat. Based on recent habitat information, we conducted a survey of river snails and found a relatively high habitat density in a branch stream of the Sabi River. We would like to work on the propagation of Tondabayashi genji botaru in the future. [/box] [box color="lgray"]

Radiation and Our Lives ( Kyoto Koka Senior High School, Primula Course, 2nd Year )

First, we examined basic knowledge about radiation and natural radiation exposure. Natural radiation exposure refers to radiation exposure in daily life, and the amount of exposure varies from region to region. The amount of exposure varies from region to region, especially in foreign countries, where it is 10 times higher than in Japan. However, even in high-dose areas, it is believed that natural exposure has no effect on the human body. We have further examined the issue of low-dose exposure based on this knowledge. Although there is much controversy over whether a threshold exists for stochastic effects, we have proposed a new standard, a reference value, for the annual exposure dose of 10 mSv, taking into account the effects of natural exposures in various regions of the world. We believe that setting a threshold will lead to a new understanding of policies and measures related to low-dose radiation exposure. [/box] [box color="lgray"]

Sunspot Observation 2013-2014 ( Hyogo Prefectural Sanda Shounkan High School Astronomy Club Solar Observation Group )

We, the Sanda Shounkan High School Astronomy Club, have been making sketches of sunspots and observations with a single-lens reflex camera. We report the calculation of the sun's rotation period based on our daily observations and the results of comparing sketches of sunspots and images taken with an SLR camera. [/box] [box color="lgray"]

Meteor shower activity by radio wave observation ( Hyogo Prefectural Sanda Shounkan High School Astronomy Club Meteor Observation Team )

Radio observation of meteors is a very effective means of observing meteors that is not affected by the time of day or night, weather, or moonlight. We have been continuously observing meteors at our school. We will report on the activity of meteor showers as seen from the results of these observations. [/box] [box color="lgray"]

The Secret of the Changing Morning Glory ( 1st Year Volunteers, Nara Prefectural Seisho Junior High School )

The wild form of the morning glory has blue round flowers and three-pointed leaves. However, in our cultivation of four varieties of morning glories, we found plants with elongated leaves like willow leaves, and plants with flowers similar to those of gentians and nadeshiko (Japanese nodding lily). From seeds of the same cultivar, two plants with three types of flowers and two types of leaves appeared in two cultivars, and three types of flowers and one type of leaf appeared in one cultivar. One plant did not form seeds and was found to have willow leaves, deeply lobed petals, no cotyledons, and three lobed column heads. Since the deeply lobed petals also had three lobes on the head, we hypothesized that the same gene was responsible for the deep lobes on the petals and the three lobes on the head. In addition, the plants with petals curled toward the front had approximately the same number of pores on the front and back of the leaf, suggesting that there is variation in the axes of the front and back during leaf and petal formation.

Population Change of Red Rats over 11 Years: Reconsideration of the Relationship with Climate Change ( Konan Senior High School, Science and Mathematics Course, Special Experiment Rats Group )

We conducted an 11-year study of small mammal populations in Kumihama, Kyoto, Japan. The results showed that the number of red rats fluctuated between 0 and 19, and last year's analysis showed that the amount of snowfall in January and the temperature in March had an effect. However, when predictions for 2014 were made based on these results, the predictions were blurred, and the way this data was compiled did not clearly show a relationship between the factors. This indicated that a more precise analysis was needed. Instead of separating the data by month, we will present a more detailed analysis of the data, including the amount of snowfall and the degree of temperature change, with the goal of elucidating the relationship between abundance and climate change.

Elucidation of the mechanism of plankton outbreaks of two plankton species (Konan High School Science and Mathematics Course Special Experiment Plankton Research Team)

We have been conducting an annual plankton survey in Kumihama Bay, Kyoto Prefecture, Japan. Kumihama Bay is a lagoon, and there are large differences in water quality between the inside and outside of the bay, which may have an impact on the fauna. This year's results, the 11th year of the plankton net survey, showed not only differences in plankton fauna between the inner and outer bays, but also a clear increase in the number of radiolarians in the inner bay, and in the coastal area, and a clear increase in the number of yakotus in the coastal area. In the bay, radiolarians were clearly more abundant than in previous years. Therefore, the purpose of this report is to elucidate why these two species were observed in greater numbers, while taking into account the results of population and water quality surveys conducted over the past 10 years.

Fluorescence of Salicylic Acid Derivatives -Basics and Applications- ( Kyoto Prefectural Momoyama Senior High School, Global Science Club )

Solid salicylic acid emits fluorescence when irradiated with ultraviolet light. Focusing on this phenomenon, we have been conducting basic research on the fluorescence of salicylic acid and its derivatives. As a continuation of this basic research, we have comprehensively investigated "fluorescence in solution" and "effects of various ion additions. In addition, to develop applications of this phenomenon, we conducted "absorption experiments on plants" and "fabrication of ultraviolet detection films". As a result, they succeeded in "confirming the phenomenon that the fluorescence intensity and color change depending on the solvent (solvatochromism-like)," "confirming the phenomenon that the fluorescence intensity and color change depending on the added ions," "producing glowing kaiware radish," and "producing a film for UV detection.

Measuring the rainbow radius ( Notre Dame Seishin Gakuen Seishin Junior High School Rainbow )

Rainbows can be seen in everyday life. They can be seen on various occasions, such as after a rain or while watering with a hose. Rainbows seen in the sky appear larger, while rainbows seen while watering appear smaller. In other words, are rainbows different or the same size depending on where they are seen? We generated a simulated rainbow and investigated its size by changing the distance from the rainbow. We considered the rainbow to be an arc, and considered whether there was a difference in size by measuring the radius of the arc. The method was to paste glass beads with a diameter of 0.4 mm onto cardboard and expose them to sunlight to simulate a rainbow. The camera is then used to photograph and print the image, find the center, and calculate the radius. We checked whether the size of the rainbow changes by changing the distance between the camera and the cardboard. [/box] [box color="lgray"]

Science of Pudding ( Notre Dame Jogakuin Junior & Senior High School High School Science Club )

Difference in salinity of seawater due to regional differences ( Notre Dame Seishin Gakuen Seishin Junior High School, Kaishui )

The salinity of seawater is generally said to be 3%, but we measured whether there are differences among regions: we collected seawater offshore or on the coast of five locations, including overseas, from July to September, measured the amount of salt left by evaporating them, and calculated their concentration. The results showed that the concentration was more than three times higher than the commonly accepted value. However, it is possible that the salt was weighed without completely evaporating when the experiment was conducted, or that impurities were mixed in with the remaining salt, so we redid the measurements at one location based on our reflections.

Development of handmade soap using local products of Yuge Island ( 1st and 2nd year students, Yuge National College of Technology, National Institute of National Colleges of Technology )

Currently, various types of soap are on the market, but due to problems with additives, an increasing number of women are making their own soap from olive oil and other ingredients. In addition, salt production on Yuge Island has a long history, and seaweed salt is sold as a local product. With the aim of commercializing this product in the future, we made soap using Yuge Island's algal salt. Four prototypes were made using different combinations of olive oil, white sesame oil, coconut oil, and palm kernel oil, and were monitored by women. The results showed that the soap made with sesame seed oil and coconut oil received the highest evaluation, while the soap made with sesame seed oil and coconut oil received the lowest evaluation among women in their teens and twenties. Olive oil and coconut oil soaps were highly rated by teens and 30s. [/box] [box color="lgray"]

In search of an eraser that erases well ( Notre Dame Seishin Gakuen Seishin Junior High School, 3rd grade, Class A )

Purpose: We use erasers in class and on tests every day. So, we wondered which manufacturer, color, and type of eraser is the easiest to erase.
[Methods

1. Transcribe 20 "A "s.
2. Erase each of the 10 different erasers twice vertically and count the number of erased round trips.

Results: We found that three types of erasers were easier to erase, so we continued the experiment with these three.
[Methods

1. Write 30 "A "s.
2. Erase vertically and horizontally five times with each of the three types of erasers to be experimented with, and count the number of erasures.
3. Ask 3 people to do 1, and the same person erases it.

Result] MONO Black tended to be easy to erase, and White was hard to erase in this group. Vertical and horizontal did not show significant differences. [/box] [box color="lgray"]

Where are molds and bacteria? How to live a hygienic life ( Notre Dame Seishin Gakuen Seishin Junior High School, 3rd year, Class B )

Purpose: Mold is one of the most common problems during the rainy season. I wondered what kind of environment is most prone to mold formation. This will help us to understand where we need to be conscious of cleaning, so that we can lead a hygienic school life.
[Methods] Petrifilm (3M Healthcare) used in food hygiene inspections was used. The types were mold, general bacteria group, and coliform group. The area to be inspected was wiped with a moistened cotton swab and diluted. 1 mL of the diluted liquid was ingested on a plate and left for 2 days, and the colonies were observed.
Result] There was no mold in toilet bowls and other places with antimicrobial treatment. General bacteria were everywhere. E. coli was in buckets and tablecloths. [/box] [box color="lgray"]

Will it rain with a precipitation probability of 50% ( Notre Dame Seishin Gakuen Seishin Junior High School, 3rd year, Class C )

Objective: We looked at the weather forecast and the probability of precipitation every morning and wondered whether we should bring an umbrella, and wondered at what percentage or higher the probability of rain would increase. Therefore, we used the media (newspapers, news, and the Internet) every morning to check the weather forecast in southern Okayama Prefecture. We decided to examine the precipitation probability of weather forecasts reported in newspapers and on TV to help us make our own decisions.
Methods: The probability of precipitation and weather forecasts from September 2 to October 2 (not including Saturdays, Sundays, and holidays) were obtained from the Sanyo Shimbun, Asahi Shimbun, Yomiuri Shimbun (all newspapers are morning editions), Good Morning (TV Asahi), Asa-chan (TBS TV), and the Japan Meteorological Agency. Actual precipitation probabilities were calculated based on this data.
[Result] Still under investigation. [/box] [box color="lgray"]

Consider an+b analogous to the Collatz problem ( ssh course, Nara Prefectural Seisho Senior High School, 2nd year, class 4, mathematics group M2 )

The Collatz problem is "Take a positive number n, if it is odd, multiply it by three and add one. If it is even, divide by 2. If you repeat this, no matter what n you choose at the beginning, at some point you will repeat 1→4→2→1". This has been verified by computer up to n quadrillion, but it has not been mathematically proven and is an unsolved problem. We will approach the Kolatz problem through numerical experiments by extending the even and odd case of this problem (e.g., if n is divisible by 3, divide by 3; if n is divisible by 3, multiply by 4 and subtract 1; if n is divisible by 3 and has 1 remainder, multiply by 4 and subtract 2).

Renewable Energy - Potential of Small Hydropower and Tidal Power Generation ( Kyoto Koka Senior High School, 2nd year, Primula Course )

Since the Great East Japan Earthquake, which marked a major turning point in Japan's energy policy, power generation using renewable energies has been attracting attention. In this report, we focus on hydroelectric and tidal power generation from Japan's abundant water resources among renewable energies. We investigated the types of small-scale hydropower and tidal power generation, their current status, merits and demerits, and discussed them to formulate a practical plan for the further spread of hydropower in the future. [/box] [box color="lgray"]

Bioethanol Production Experiment - How to Spread Bioethanol in Japan - ( 2nd year student, Primula Course, Kyoto Koka Senior High School )

We conducted an experiment to produce bioethanol, which is attracting attention as a next-generation energy source. We studied basic knowledge about bioethanol, such as its current status and carbon neutrality, and listened to a lecture by a professor from Nagahama Institute of Bio-Science and Technology to learn about manufacturing methods and issues to be addressed when bioethanol is widely used in Japan. From there, we procured raw materials and conducted production experiments with the aim of producing bioethanol from industrial waste containing cellulose. As a result of various investigations, we were able to obtain waste igusa from tatami factories. Based on the raw materials, we were able to actually produce bioethanol using the facilities of Nagahama Institute of Bio-Science and Technology. The poster summarized the results of the study and the issues that came to light. [/box] [box color="lgray"]

Cultivation experiment of Yumechikara (wheat) ( Science Research Club, Hyogo Prefectural Kobe Commercial High School )

Yumechikara is a variety developed by Shikishima Bakery that is suitable for growing in the hot and humid climate of Japan. The company applied for the Yumechikara cultivation research project, a project to achieve 200% self-sufficiency using this wheat, and received the seeds for cultivation.
Kobe Commercial High School does not have a place to grow wheat or set up a large planter. Therefore, we decided to try growing wheat in plastic bags and planters, in addition to the PET bottle cultivation1) that is often used for rice cultivation, to explore a method of wheat cultivation that can be done at school. We also changed the composition of fertilizers and investigated their effect on yield. [/box] [box color="lgray"]

History of "Water on Mars": How the Water on Mars Traced its Path to the Present ( Kyoto Municipal Murasakino High School Summer Poster Presentation Volunteers )

Recently, terraforming (emigration) to Mars has become a hot topic due to environmental changes on Earth, and "Mars" has become more and more familiar to me. There are many things that are necessary for the realization of terraforming, and I am interested in "water. It is known that liquid water existed on Mars in the past, but it does not exist in liquid form now. I thought that if I knew how it came to be, I could get closer to the realization of terraforming.

Effective use of hypnosis ( Kyoto City Shino High School Summer Poster Presentation Volunteers )

You have probably heard somewhere that people usually use only a fraction of their natural abilities. If you think about it, you probably feel that you are not utilizing 100% of your motor skills, memory, and so on. So, why do we not use our natural abilities in such a way? What controls it and why do we do so? I have studied our "subconscious mind" and the "hypnosis" that can manipulate it, and have tried to find out if we can effectively use our natural power.

Preparation of detergent and study of laundry wastewater by bioluminescence ( Chemistry Group, Natural Science Department, Jeami Senior High School )

The objective of this activity is to create a detergent for clothing that has high cleaning ability but does not fade colors. The environmental impact of the detergent will also be examined.
The research is being conducted in two groups: a detergent production group and an environmental verification group.
First, to determine the optimal concentration of surfactant among the detergent components, we soiled gauze with soy sauce and other ingredients, dipped it in solutions of various concentrations of surfactant, and examined how well the stains were removed.
For environmental verification, a method was devised to determine how long organisms can live in the effluent after washing. This method visually confirms the presence and death of microorganisms by using Hotalite.
We hope to advance to the point where we can validate the detergent produced by the time of the presentation. [/box] [box color="lgray"]

Presentation on spiders and insects ( Takigawa Junior & Senior High School Biology Club )

1. I will be presenting on the "threads" used to build the webs of the wolf spider and the jumping spider, as well as the "threads" used in special cases. I have been interested in spiders since the first grade of elementary school and have continued to observe them.
2. We, the biology club, have been continuously surveying and observing the insect fauna around our school (Suma-ku, Kobe) since the spring before last. The surrounding environment is a fascinating place with many wooded areas and grasslands, and despite the fact that it is adjacent to a residential area, it is home to a large number of insects. We observed and collected them and created a table of their seasonal appearances. Some of the specimens will also be on display.

In Search of Delicious Water in Yakushima ( SSH Forest and Water Exploration Group, Junior High School attached to Okayama University of Science )

We drink about 1.5 liters of water every day. We often use PET water, and we began to wonder if the taste of various types of water might be different. One of our school's super science nature experiences was the "Yakushima Forest and Water Training" and we decided to participate in it and investigate water in a natural heritage forest. We all decided to drink the water and check the taste and chemistry of the water with the natural original spring water. We heard that the water in Yakushima is delicious, so we planned to compare the taste and composition of the water in Yakushima, and to compare it with PET water and with tap water to determine the original quality and taste of nature's water.

From the summer camp on stork conservation activities ( Kansai University Hokuyo Junior High School Science Club )

Our Science Department holds a summer camp during the summer vacation in early August. This year, the students visited the Storks' Home Park in Toyooka City, Hyogo Prefecture, to learn about the ecology of storks and local conservation activities, and then observed storks being raised in gauges. They then moved to the Takeno Snorkeling Center to conduct an experiment on the development of sea urchins, where they observed how fertilized eggs increase their cell number through cell division. On the following day, they observed sea fans, spider starfish, seahorses, and other shore creatures. On the day of the event, second-year junior high school students gave a presentation on their observation of sea turtle spawning, and first-year junior high school students gave a presentation on this presentation, reporting on their efforts to use the school's off-campus activities.

Survey of Cicada Shells in and around Shinwa Girls' High School 2014 ( Sophomore, Biology Department, Shinwa Girls' High School )

It is believed that the species of cicadas are to some extent determined by their natural environment. Since 2013, the Biology Department of the school has been investigating whether the species of cicadas that inhabit the school vary depending on the environment, taking advantage of the school's location between the two environments of Mount Rokko, which is rich in nature, and the city.
As a result, it was found that in both years, the number of Aburamemi was higher at the mountain side of the survey site, which is closer to Mt. The difference in the distribution of cicadas between the mountain side and the urban side may be due to the difference in environmental conditions between the survey sites. As one of the conditions, we would like to discuss how the differences in tree species between the survey sites are related. [/box] [box color="lgray"]

Report on the Sea Trials ( Shinwa Girls' Senior High School, Biology Department, 2nd year junior high school students )

As part of the Biology Club's summer camp, the club held a critical training session at the Marine Site of Kobe University's Center for Inland Marine Environmental Education and Research. Eleven Biology Club members, ranging from 2nd year junior high school students to 2nd year high school students, participated, observing the development of sea urchins, making seaweed specimens, and collecting and observing plankton. Here is a poster outlining the practical training and what the club members learned, wondered about, and were interested in through the training. [/box] [box color="lgray"]

Observation of planarian regeneration ( Shinwa Girls' Senior High School, Biology Department, 1st year high school students and 1st year junior high school students )

I was interested in the planaria in the aquarium in the classroom where I am involved in club activities, and decided to investigate their ability to regenerate when I became a high school student. Therefore, we conducted the following experiment to find out how long it takes for planaria to regenerate, and whether the point at which regeneration begins differs depending on the way the planaria is cut.
The planaria used in the experiment were placed in five petri dishes of five animals each and raised in a cryocooler. The planaria were fed with cyprinid worms for the first three months and thinly sliced bird liver for the next two months, both once every two days. During the experiment, the planaria were placed on a petri dish filled with water and frozen to slow their movement. The birds were then cut in six different ways and observed to see if regeneration proceeded as hypothesized for each. [/box] [box color="lgray"]

Measurement of antimicrobial effect of natural essential oils using paper discs ( Yamamura Gakuen Yamamura International High School, Biology Club )

The motivation for this research is that natural essential oils are aromatic components extracted from plants. Therefore, we hypothesized that aromatic components would have antimicrobial properties, and began research on their antimicrobial effects. We selected 6 pairs of natural essential oils and 10 types of aromatic components. Commercially available disinfectant sprays were also included as controls. The antimicrobial effect was measured by the paper disk method, which was improved for quantification, and compared with other samples based on the inhibition circle that inhibited the growth of Bacillus subtilis natto on the agar medium. The antimicrobial effect of natural essential oils was related to the characteristics of the functional groups of the aromatic components and the aromatic note (volatility). The spray made with natural essential oil was superior to the antimicrobial effect of commercial disinfectant sprays. [/box] [box color="lgray"]

How to Preserve Green Salad ( Yamamura Gakuen Yamamura International High School, Biology Club )

≪Motivation for the study≫ Salads are easily damaged during the summer. Therefore, we thought of a preservation method for salads placed in the classroom during summer supplementary classes to be eaten at lunch time without worry. ≪Research Method≫My senior researcher used vinegar in his antimicrobial study, but this was too acidic and tasteless. Therefore, taking a hint from the antimicrobial action of citric acid (hypothesis), this time lemon juice (an antimicrobial ingredient) was sprinkled on the salad and studied under the storage conditions of 28°C and 6°C. ≪Results and Discussion≫If the salad was sprinkled with at least 2 mL of lemon juice, the growth of bacterial colonies was suppressed at 28°C (assumed classroom conditions) as well as at 6°C (assumed refrigerator conditions). However, no first-year club members have yet eaten the fresh, warm salad. We are currently developing an antimicrobial dressing that will reduce this raw-warmth effect. [/box] [box color="lgray"]

Robot arm production ( Osaka Prefectural Tondabayashi High School Science Club Robot Team )

This year, we made a robot arm that lifts an object by operating a switch. We considered that the robot arm needs three movable parts (elbow, wrist, and hand) to grasp and lift a target object, similar to the structure of a human arm. We considered a structure in which these parts are operated by a motor and a gearbox, but since they all require opposite movements (left-right, up-down, open-close), we used a "toggle switch" for the switch that can switch the direction of the electric current in the opposite direction and rotate the motor in the opposite direction. As a result, the robot successfully grabbed and lifted a target object such as an eraser. Next, we would like to try making a "sensor-sensing robot arm" incorporating last year's sensor-sensing technology. [/box] [box color="lgray"]

Ishikawa's Efforts to Revive Ayu and Eel ( Osaka Prefectural Tondabayashi High School Science Club, Fish Group )

In last year's study, we found that ayu, which are abundant in the Yamato River, do not live in the Ishikawa River because they cannot migrate upstream due to the weir at the downstream end of the river. This year, we investigated whether ayu could inhabit the Ishikawa River if they were able to migrate up the weir. As a result, we found that there are as many as 10 weirs in a 10-km section of the lower reaches of the Ishikawa River, and that five of them have fishways designed for ayu migration. In order to investigate the function of the fishways, we conducted an experiment using ayu collected in the Yamato River, and confirmed that ayu runs upstream. Therefore, the only two weirs that obstruct ayu run-up are those without fishways and with large drop-offs, and if fishways can be installed at these weirs, ayu are likely to inhabit the 10-km section downstream of the Ishikawa River.

Yumechikara Project: Ikuno High School's Challenge ( Osaka Prefectural Ikuno High School, Biology Club )

The Ikuno High School Biology Club, together with the Home Economics Club and the PC Club, participated in the Kinki Region "Yumechikara Project" and spent a year growing wheat "Yumechikara" in planters. We tried to increase the protein content of the wheat so that the bread would be chewy, while using different fertilizers. Although the harvest was not very large due to aphid damage and water loss, we were able to grow wheat with a high protein content. Finally, together with the home economics club, we made bread rolls from the milled wheat and tasted them. The same bread was made with commercial flour and compared. [/box] [box color="lgray"]

Crystal and Glass Structures of Kyo-yaki Ware and Color Change of Glass-Metal Composites ( Kamoyi High School, Kyoto, 2nd year, Lecturer 66 )

Kiyomizu-yaki, one of Kyoto's traditional arts and crafts, and other ceramics known as kyoyaki have been made using heavy metals and other materials as glazes to produce brightly colored ceramics and porcelain. The use of lead, an essential ingredient in kyoyaki, has been banned in many modern countries, especially in Europe. However, the vivid yellow color is unique to lead, and cannot be obtained by substituting other rare earths. This article chemically examines Kyoto's culture of kyoyaki pottery and environmental issues. [/box]
