| summary | The water in Sunpu Castle moat varies in color, volume, transparency, etc., depending on the location and season. However, the water quality of Sunpu Castle moat has rarely been investigated, and the cause was unknown, so we began a detailed investigation of the water quality. The results of the pack test showed that compared to the water quality standards set based on data from the Ministry of the Environment, the water quality at two points in the outer moat where there were many fallen leaves and at one point in the inner moat where there were many carp inhabiting the deep moat exceeded these standards and the water was dirty. Microscopic observations also revealed a correlation between water temperature, sunlight hours, and phytoplankton. |

| summary | This study investigates the relationship between spring water temperature and precipitation at Otomeyama Park in Shinjuku City, which has spring water. The purpose of this study was to analyze the detailed mechanism of temperature displacement of the spring water in the city center, where depletion of spring water has been considered a problem, in order to improve the effectiveness of measures for the conservation of spring water. The previous study showed that spring water temperature fluctuates on spikes during rainfall, but in fact, there was a temporary temperature drop in winter and a temperature increase in summer. This is thought to be due to shallow groundwater being pushed out by rainwater. |

| summary | A red tide is a phenomenon in which a large number of red tide plankton are produced, causing damage to fisheries and other industries. However, red tide diatoms can be utilized as feed. To confirm this, we first focused on Skeletonema costatum. We cultivated Skeletonema costatum for about 2 weeks and used it as feed for omnivorous crustacean shrimps. As a result, we succeeded in rearing not only in Skeletonema costatum water but also in red tide water. This indicates that red tide can be used as a food source. In the future, we will further explore the possibility of using red tide as a feed. |

| summary | Some of the chemical substances that pollute rivers and lakes have adverse effects on living organisms. We aimed to purify LAS, a type of surfactant contained in detergents and other products, by utilizing oxeye grass and microorganisms, which have a low environmental impact. We conducted a control experiment because we believe that the symbiosis of sea squirt and microorganisms increases its purification ability. The LAS values decreased the most under the condition of the symbiosis between Uxixa and microorganisms, and we believe that the combination of Uxixa and microorganisms is an efficient purification method. |

| summary | Currently, research on new energy sources is underway due to concerns over dwindling fossil fuels and other resources and environmental pollution. In order to listen to music with microbial energy, one of them, the amount of electricity generated was measured using microbial fuel cells under various conditions. The results showed that the highest amount of electricity was generated when the cells were placed at 37°C with the addition of ferric oxide. We surmised that this was probably due to the abundance of iron oxide in the deep sea where the Schwanella bacteria are found. Since Schwanella is an anaerobic bacterium, we would like to further investigate conditions to further increase the amount of electricity generated, such as conducting experiments under vacuum conditions. |

| summary | Polyethylene terephthalate (PET) is not easily degraded in nature due to its structural stability. Under these circumstances, PET-degrading enzymes derived from bacteria have attracted attention. In this study, we attempted to express PET-degrading enzymes inside E. coli and release them outside the cell to degrade PET. However, no mass change of PET was observed with this method, so we examined the reaction with purified enzymes. Degradation activity was confirmed only by experiments using polycaprolactone-added medium and thin-layer chromatography. If PET degradation by this method becomes feasible, effective PET degradation using enzymes would be expected. |

| summary | The purpose of this study is to approach the reduction of plastic waste by estimating the drift period of plastic waste. Each type of plastic has its own characteristic infrared absorption wavelength, which can be identified by FT-IR. The shape of the IR absorption spectrum changes depending on various factors. This change may be used to estimate the drift period. The actual analysis by irradiating the samples with UV light showed a change in the plastic structure. We believe that more accurate data on plastic degradation can be obtained by increasing the number of samples and conducting further analysis. |

| summary | This study is a study of the mozuku (Cladosiphon okamuranus), which was observed growing in Wako City, Saitama Prefecture. Although mozuku is currently listed as a critically endangered species, it used to be a relatively common food in the region, as it was used as a food source. Therefore, we thought it would be possible to cultivate mozuku by utilizing the cultivation techniques of the Japanese spineless mozuku, which we have been working on in our previous research. Since the life cycle of the mozuku has not been elucidated, we would like to establish culture conditions by first exploring the conditions for induction into the body. |

The hypothesis was that micro-leg movements during work would activate the brain. From experiments, we investigated the effects of micro-oscillatory exercise on the brain in terms of memory, spontaneous force, and concentration. The results showed that the micro-jogging exercise during work decreased memory and spontaneous force, but tended to improve concentration. It was suggested that the decrease in work efficiency in terms of memory and instantaneous force was caused by consciously performing multiple tasks at the same time. |

I found that people who are good at exercise tend to like spicy food and eat a lot of it, and that they eat a relatively large variety of vegetables. From this, we hypothesized that people who are good at exercise are careful about nutrition. In addition, because we thought that adrenaline was related between spicy food and exercise, we conducted an experiment to determine whether there was a difference in athletic performance between those who ate spicy food and those who did not, and predicted that athletic performance would increase when spicy food was eaten. |

To examine the effect of the color of the rearing containers, black and light blue containers were prepared. The fry were reared in each of the two zones, and the intensity and composition of the red pigment after fading were compared and analyzed. The results showed that ultraviolet light had no effect on the fading of the fry. The color of the rearing containers affected the fading of the fry and increased the synthesis of red pigment. |

In our school, we conducted green light irradiation experiments using flatfish, a species closely related to Pinguinus capitata. In previous experiments, growth was accelerated by green light irradiation even under unfavorable conditions such as low water temperature and shallow water depth. Next, we found that it is possible to raise flatfish in brackish water by gradually decreasing the salinity. Based on these basic studies, we have developed a land-based aquaculture flatfish production system (flatfish production factory). We designed and fabricated a staircase type and a vertical type, depending on the application. |

Therefore, we decided to clarify its entire life history and have been studying it continuously since 2016. Among other things, it is unclear where Zoea larvae reach the vicinity of the estuary and then metamorphose into megalopa larvae, and we attempted to collect them by plankton netting and identified several megalopa larvae from the collection site closest to the estuary. This suggests that Zoea larvae can reach (or before reaching) the river mouth, metamorphose into megalopa larvae, and then swim upstream and metamorphose into adults. |

The average temperature in the Yamanaka region has been warming, but has been affected by hiatuses in recent years. The number of tall trees in the Harimomi forest has decreased over the years and is currently around 550. The causes are thought to be fire, typhoons, and longevity. The forests are rich in mosses, fungi, and lichens, which retain moisture on the forest floor. The future of the pure forests of Halimomi will not be the extinction of Halimomi, but a mixed forest of needle and broadleaf trees. |

| summary | This experiment was conducted to clarify the relationship between oxygen and carbon dioxide and tissue culture of Portulaca. Based on previous studies, we hypothesized that higher oxygen concentrations would slow callus formation and higher carbon dioxide concentrations would promote callus formation. As a result, plant growth was accelerated and callus formation occurred in the environment with high oxygen concentration, but in the environment with high carbon dioxide concentration, the growth rate was the same as in the normal environment. From these results, we hypothesized that in portulaca tissue culture, an environment with a high oxygen concentration would stimulate respiration and speed up growth. |

| summary | The full picture of the genes involved in newt regeneration is still unknown, and the intracellular molecular processes involved have not been fully elucidated. One of the genes that is believed to be involved in this regenerative process is nsCCN. Previous studies suggested that nsCCN may be involved in the process of regeneration [1][2][3]. Assuming that nsCCN is involved in the whole body regeneration process in newts, this study examined nsCCN expression in limb regeneration. nsCCN was suggested to be expressed on the amputation surface 1 day after amputation. nsCCN was found to be expressed on the amputation surface at the first day after amputation. |

| summary | Previous studies have shown that planaria are affected by changes in water temperature and breeding water, but the details are still unknown, so we aim to elucidate the details. We hypothesized that the surrounding environment would alter the body size of planaria. For the experiment, planaria were kept in 20 mm diameter bottles, 63 mm diameter and 45 mm diameter petri dishes and fed bird liver for 30 minutes. The experiment was also conducted under constant darkness and lasted for 2 weeks. As a result of the experiment, planaria in the bottles were 60% smaller than before the experiment, and planaria in the petri dishes were 501 TP3T and 81 TP3T smaller. These results suggest that the surrounding environment affects the body size of planaria. |

| summary | Crayfish are known to coexist with a group of annelid worms called hirundo worms, and in recent years, American hirundo worms (Ohtaka, unpublished), native to the United States, have been discovered in rivers in Tokyo. Therefore, we investigated the distribution of this species at 10 sites in the Maruike, Senkawa, and Nogawa Rivers in Mitaka City, Tokyo. As a result, we confirmed the presence of American water flea worms in the Sengawa and Nogawa Rivers, as well as their coexistence with a species of the genus Kawarinumaebi. This is the second case of this species being discovered in Japan, and it is clear that the distribution of this non-native species is expanding. |

| summary | It is known that germination of plantain seeds at the same time as white clover seeds is faster than germination of plantain seeds alone. However, the mechanism is still unknown. I became interested in how plantain seeds accelerate germination and began research, conducting seven experiments and finding that germination is accelerated not only by plantain seeds but also by white clover seeds and poison ivy seeds, and that germination is not accelerated when seeds are exposed to heat or ethanol. The study also found that exposure of the seeds to heat or ethanol abolished the germination acceleration phenomenon. |

| summary | Olfactory signals are sent to the ectopia and hippocampus, and these brain regions are known to be associated with emotion and memory. Since the characteristics sent to these brain regions are not present in other sensory signals, their influence on memory may be significant. In this study, we measured memory performance under exposure to odors and investigated which odors are effective for memory consolidation. The results of a comparison using extracted plant odors and aroma oil showed that memory was improved more when the odor was present than when it was absent. In the future, we will examine the concentration of oil dilution and other odor components, and clarify how to utilize odors to increase memory more effectively. |

| summary | We learned that Delovibrio sp. has a preference for Gram-negative bacteria, and began researching the possibility of using this preference for vegetable production. Our hypothesis was that Delovibrio sp. would have a preference for blue blight. The expected result was that Delovibrio sp. would have a preference for the blue blight bacterium. As a possible consideration from the results, we considered that Delovibrio sp. has the potential to be a biopesticide because of its predatory nature on blue blight bacteria. |

| summary | When foaming bath salts are added to a bathtub, bubbles are produced. The bubbles are carbon dioxide produced by the chemical transformation of sodium bicarbonate and fumaric acid in the ingredients. We were interested in this phenomenon. In our research, we used a sample mixture of baking soda and citric acid to simulate the approximate conditions of the bath salts for the purpose of more accurate numerical measurement. A scab bag was used to collect the gases generated by the dissolution. Water and the mixed sample were filled into the bag, and the masses were compared before and after dissolution, and the molecular weights were calculated. The solubility of the mixed sample dissolved in water was investigated at the applied level. |

| summary | Chemistry textbooks describe "properties of dilute solutions". In a solution, the vapor pressure becomes lower than that of the pure solvent and the boiling point becomes higher than that of the pure solvent, "boiling point rise", and the freezing point of the solution becomes lower than that of the pure solvent, "freezing point depression". The degree of boiling point rise and freezing point fall are expressed as "Δt=K⋅m". However, there is no description of the standard for the concentration of "dilute". Therefore, we are conducting research to find the boundary between dilute and non dilute concentrations. We first studied freezing point depression and identified the concentration limits that apply to Δt=K⋅m. |

| summary | Dye-sensitized solar cells (DSSCs) have no difference in light conversion efficiency compared to other solar cells, but their durability is low, so there is a need to improve their durability and further increase their light conversion efficiency. In this study, we focused on the molecular weight of polyethylene glycol (PEG), the material used for the TiO2 electrode; as the molecular weight of PEG increased, the surface of the TiO2 film after sintering became granular. This result indicates that TiO2 becomes more porous as the molecular weight of PEG increases. Therefore, the dye can be adsorbed more by increasing the molecular weight of PEG. |

We hypothesized that by reducing the pungent odor of the ester, it would be closer to the original aroma of the fruit, and people would perceive it as a delicious aroma. The results in the intermediate stage showed that the carboxylic acid had a strong pungent odor. We believe that changing the amount of carboxylic acid and alcohol in the mixture will make a difference in the aroma. |

We wanted to conduct a similar experiment in a high school laboratory, so we undertook a study of plasma generation by dielectric barrier discharge using a power supply for neon signs. In this study, we first confirmed whether or not plasma is generated by dielectric barrier discharge using a power supply for neon signs, and then investigated the differences in patterns when the thickness of the atmospheric atmosphere layer is changed. Currently, we are analyzing the changes in patterns with the thickness of the atmospheric atmosphere layer. |

By expanding the honeycomb paper, the cell area increases and the areal density of the paper decreases. When a weight was dropped onto the honeycomb paper and its strength was measured, a decrease in strength proportional to the density was observed. However, the design of the sample used in this study was found to maintain sufficient strength as a helmet even at the lowest density. |

| summary | Nanbu-cho, Aomori Prefecture, is a town with a thriving fruit tree production industry. However, the average age of farmers is 65 years old, and the population is aging. We hypothesized that pollination could be simplified by spraying pollen solution from above, and conducted an experiment to reduce work at high altitudes and shorten work hours. As a result, the fruiting rate of the central fruit was 58.8% this year. The result at the cooperating farmers was 46.7%. The difference is thought to be due to the aerial drone pruning method used at the school to reduce overlapping branches, as well as the shape of the farmer's trees. |

| summary | In this study, we focused on catechins, one of the functional components of tea, and attempted to improve the elution efficiency from tea leaves and establish a more effective utilization method. The amount of catechins eluted from tea leaves increased with increasing elution temperature, but they remained in the tea leaves after multiple elutions, suggesting that there is a limit to the elution with water. When ethanol was used as the extraction solvent, the elution of catechins increased regardless of the concentration. The catechin content in the tea leaves was maintained by the drying method without heating. |

| summary | Around us, fading is often seen on signs, billboards, and posters. We thought that if we could understand the cause of the large fading and develop an ink with anti-fading measures, it would be possible to preserve important information outdoors for a long period of time. In last year's research, we observed differences in the fading of paper strips that had been colored with a pen by UV and fluorescent lamps, and the faded pigments were extracted and analyzed by paper chromatography. We hypothesized that the color fading was "due to the absorption of short wavelength light by the warm pigment, which shortens the molecular chain to form a new pigment," and we will verify this hypothesis numerically using a spectrophotometer. |

| summary | In this study, solar radio waves are observed using a commercially available BS antenna. To briefly explain the mechanism, 1) radio waves emitted by the sun are observed with a parabolic antenna, 2) the received signal is amplified with a BS booster (amplifier) because it is very weak, 3) the high-frequency signal is rectified to direct current with a homemade detector, and 4) the voltage of this rectified signal is measured. By measuring this voltage, we can observe the sun's radio waves. The device is still under development, so we do not know the exact data, but it is thought that the voltage will be larger when the parabolic antenna is pointed at the sun than when it is pointed at the sky. |

| summary | The purpose of this study was to review the current capsule form and to prevent aspiration of medicine, and the hypothesis was that a form superior to the current capsule form existed. The present study revealed that a homemade biconical pseudo-medicine produced less noise during swallowing than the capsule form commonly used today. In other words, the biconical shape was easier to swallow than the capsule shape. From the results, it was concluded that the ease of swallowing depends on the size of the contact surface with the esophagus, and that the larger the contact surface, the more friction there is, and the more resistance there is to swallowing. |

When the experiment is completed, it is expected that the most healing effect will be achieved by music consisting of a specific frequency, slow BPM, and the three major elements of music. |

| summary | Focusing on the difference between the efficient way of conveying information in a presentation and the way we think about it in our daily lives, we considered that the visual sense is good at quickly receiving abstract information and the auditory sense is good at receiving more concrete information, based on the presentation, and we asked subjects to give the content of the presentation under different conditions. We will convey the content of the presentation to the subjects and consider the conditions under which the information is more easily conveyed based on the subjects' level of comprehension. |

| summary | We thought that activating conversation is important in various situations and that music can influence the activation of conversation. Among them, we thought that the type of music would influence the activation of conversation, and specifically investigated which genre of music (pop, jazz, rock, or hip-hop) would be most suitable for creating an environment conducive to activation, based on the number of times people spoke. The results showed that all genres except pop music had a positive effect on conversation activation. Based on this, we believe that these three types of music would stimulate discussion and conversation. |

| summary | We have initiated a study to survey the habitat of the endangered northern medaka using environmental DNA and to create a habitat map. The objective of this study is to conserve the endangered species. First, after confirming the usefulness of the primers using samples of water and body surface scrapings of the northern medaka, electrophoresis was conducted on actual water samples collected from lakes and rivers. At two of the three sites studied, bands appeared in positions that were not correct. Therefore, we considered the possibility that the primers amplified genetic regions other than those of the northern medaka, or genetic disturbance of the northern medaka in the southern part of Yamagata Prefecture. |

| summary | For the past four years, until last year, senior members of the company had conducted a distribution survey of medaka inhabiting the Aizu region of Fukushima Prefecture. This was a subspecies distribution information obtained through genetic analysis by surveying 41 locations and collecting samples of 119 individuals from 17 study sites. However, the information obtained was not definitive for a variety of reasons. Therefore, an "environmental DNA" survey was conducted to ensure the reliability of the information. The survey is still ongoing, and it has confirmed the invasion of the southern medaka and the presence of the northern medaka in new areas. |

| summary | Motsugo can be apparently distinguished from the endangered Sinai motsugo by the longitudinal stripes formed by scales with many black chromatophores on the sides of the fish body. Since the difference between the two may result in differences in survival or reproductive strategies, we decided to investigate body color variation and its role in the longitudinal stripe pattern area of mottled mottled mottled mottled mottlefish. Previous studies have shown that the scales of the longitudinal striped area show a greater degree of variation in the shape and size of the chromatophores than the dorsal and ventral areas, that the number of chromatophores increases with growth, and that the individual chromatophores respond to changes in shape and size by sensing differences in color hue. |

| summary | The major attraction of Fukue Island, Nagasaki Prefecture, where we live, is its rich natural environment. By certifying this rich nature as a Geopark, Goto City aims not only to preserve the environment but also to revitalize the tourism industry, one of Goto's major industries. However, it was found that awareness of the Geopark among young people below high school age living on the island is low. Therefore, we created educational contents for elementary school students to draw their attention to the "rich nature of Goto City" and conducted practical activities to increase their awareness of the Geopark. |
