Curry Noddle Soup Splatters
Grade 11

Takumi UMEMOTO, Yuto TANIZAKI, Issei PRIBYL・Introduction

Introduction

Back Ground
Curry noodle soup often splatters from your bowl and leaves stains on
your fine shirts.
Then, we were strongly motivated to analyze the physical motion of
noodles and figure out some means to prevent soup from spoiling yourclothes.

・Purpose・to analyze how much power the Contra-Rotating propeller generates andconsider the efficiency

Subject of Research ①
Observation A: Movements of the noodles when they were slurped wereobserved with a high-speed cameraes. The cameraes were arranged in both
front and side of the bowl.
Observation B: we determined the time of how fast people could slurp
noodles averagely, using a stop timer.

Results①
Observation A: Drops of the soup were mostly caused when ends of thenoodles were about to enter the examiner’s mouth. Furthermore, weclarified that the objects are swallowed into the mouth while making
pendulum movements and a screw motions. To elucidate mechanisms indetail by which the mentioned movements, we conducted another threestudies.
Observation B: The average speed was 46.63cm/s. It was even slower thenormal walking speed. This figure was used in the result of Experiment B
down below.

Subject of Research ②
Experiment A: we determined the time of a pendulum to shuttle 10 times
and calculated its frequency, changing the length of the string each time.
Experiment B: we recreate the screw motion of noodles with a string andanalyzed it

Results②
Experiment A: The chart below shows the results

Experiment B: It is found that the movement can be considered as a conicalpendulum. It is due to a shape of noodle.

There could be a possibility that the string moved not only on sides but
diagonally as well, which is thought to have caused an error on values.

・Background・the Counter-Rotating propeller is usually used for reciprocating engine
such as propeller planes, but not for wind-power generation.
・I started this research, based on the idea that there seems to be some
useful ways in which the Counter-Rotating propeller can be applicative.

Objects & Methods

Consideration
・Increase Rates of Voltages
・I made wave equations of each graphs, then compared their constantsin order to calculate the increase rates of voltages.

・Experiment Device

Experiment B: we applied the formula of conical pendulum

・Formula :・y : voltages(V) A and α : constant T : time(s)The following conclusions can be drawn from above. First, angular rate of
the ends of noodles gets faster as one eats noodles. Second, velocity of theends of noodles get slower as one eats noodles.

②
・Increase Rates

Conclusions

1.2①

Theologically, soup splutters can be prevented from happening by holdingedges of noodles, making it vertical to a bowl.

電圧（V）

Experiment Objective
Considering the physical laws, we looked for the best way to minimize thesoup splatters.

Considerations
Experiment A: To express the motion of pendulum in a formula, the following
can be obtained.
T=2π√(L/g)
Theological values and actual measured values were roughly the same

・Parameter・Change the power of wind produced by the fan.
・Switch the power level of fan and measure the wind speed 40cm fromthe fan through the wind tunnel every 5 seconds for a minute,then calculate its average.
・Change the type of counter-rotating propellers.
・Set the ① and ② counter-rotating propellers, respectively 40cm and43cm from the fan.
・Set 2 types of counter-rotating propellers in order to confirm how thevalues of voltages change between counter-rotating propellers andnot counter-rotating propellers.
・ ①…6 wing ②…6 wing
Type B ①…6 wing ②…5 wing・Hypothesis
・No.1 produces more voltages than No.2 when the wind speed is certain
speed, because the propellers of No.1 rotates in the same direction and the② propeller of No.1 receives stronger wind spinned by the other propeller.

C

・From the above graphs, ① of No.1 & No.2 and ② of No.2 have similarslope, but ② of No.2 has more gentle than them, so it can be said that
there is a point that the value of ② of No.2 and ① of No.1 are the same.

Summary・According to the results and consideration, my hypothesis that the counterrotating propeller is more powerful when the wind speed is high and so thatthe not counter-rotating propeller is when the wind speed is low, seems to becorrect.
・From these results, it can be said that the counter-rotating propeller is usefulfor the wind power generation in a place which the wind speed is strong.

I like udon because it has
good elasticity. This elasticity
comes from gluten which is a protein contained inflour. It is said that, the more salt is added, the more
the elasticity increases.

The clot was divided into pieces and hung.
Two criteria for judging the hardness of gluten.
One is the load capacity which is the heaviest weight
the gluten piece could hold. The second is the
maximum length of the gluten piece.

Gluten is made with two proteins. Protein molecules
have some type of charge, so repel each other. If
salt is given, it would be separated into Na＋and Cl－.
The ion instantly unite the charged part of molecule,and weaken the charge. That could make molecules
come close to each other. They combine one after
another, and finally gluten become harder. In thisprocess the ion from NaCl should make the distanceamong molecules shorter by weakening the charge.
In the end the stretch of gluten become shorter.

Secret of black ink pen ～Black ink pen is colorful～

Chiba-higashi high school
Tomoki Ono Kouhei Nakamura＜Motive＞
We learned the Paper Chromatography in the first chemical class in the high school. At that class, we were greatly surprised that a water-based ink pen separated
into different color components, and we got to be interested in the Paper Chromatography. Latter, we found out that two certain pens varied in some color
components in spite of same color ink pens. Black ink pen has especially the interesting point, that each pen has some different color components when there is adifference in its manufacturer or kind of ink. So we studied this.
＜The principle of the Paper Chromatography(using water as developing solvent)＞
Chromatography is a way of separating mixed substances of chemicals,
using the difference of each absorptive power. The more soluble thesubstance is, the higher it travels up, and the less soluble the substance is,the lower it stop. (Pic.1)

Luminol

ExcitedThis research is about effectively making use of food loss by extracting energy. Energy can be used in fuel cells. This is very eco-friendly
energy.

Introduction
There are 6,320,000tons of food loss in Japan every year.
Measures to reduce food loss have already been taken. However
nobody has made effective use of food loss. If food loss can beextracted energy, it is more effective. It is assumed that if energy
can be extracted from food, energy can be used in fuel cells. The
target of this research is to extract much energy from food loss.

Method ：(1) We mix luminol 0.010g and NaOH solution 0.30mL into H2O 20mL. We name it “Luminol solution”.
(2) We mix NaOH solution 1.0mL and amino acids 3.0×10-4moL or 6.0×10-4moL into H2O 1.5mL.
After that, we add CuSO4 solution 0.5mL to it. Then, we pick up appearing Cu(OH)2. We named it “Complex solution”.
(3) We mix “Luminol solution” 5.0mL and H2O2 1.0mL into a petri dish.
(4) We put this petri dish in black box, and we mix “Complex solution” 3.0mL into it(Fig.3).
Then, we record “Max illuminance” 7 times by using an illuminometer, and average them.

Fig.4 Amount of pyroligneous acid for each condition

We analyzed by SHIMAZU GC2014FID◆ As the amount of CH4 increases, the amount of pyroligneous acidFig.1 Image of researchdecreases. It is because decomposed dried rice has been produced as apyroligneous acid.
◆Compared to the sample before experiment, it can be inferred thatcharcoal could be extracted by pyrolysis because the amount of charcoal
in the sample after pyrolysis is low.
◆It is suggested that Molecular Sieves 13X could promote the reaction.

Ⅱ．Experiment “Optimum amount” of amino acids
 Hypothesis
We thought that amino acids which we used 6.0×10-4mol is the best illuminance because a coordination number of Cu is 4(Fig.4). But, some papers said that acoordination number of Cu is 2 when we used amino acids. So, amino acids 3.0×10-4mol is the best(Fig.5). Therefore, we researched to use amino acids
6.0×10-4mol and 3.0×10-4mol.

CuSO4 solution 0.50mL contains Cu 2+ 1.5×10-4mol.

Consideration of Radioactive Material Removal Methodby Volcanic Ash Using Simulated Radioactive MaterialTokyo Metropolitan High School of Science and Technology
YOSHIKA Kawana, IZUMI Akiba, NATSUME Goto

Abstract

In the Great East Japan Earthquake that occurred in Japan in 2011, it was hit by a tsunami that we never experienced. As a result, at the Fukushima Daiichi Nuclear
Power Station in Fukushima Prefecture, a radiation accident occurred due to the damage of the tsunami. A large amount of contaminated water is produced bycontamination of a large amount of radioactive substances in underground water flowing simultaneously. In this study, we noticed that silicon was adsorbed by cesium inprevious studies. Since the main component of volcanic ash is silicon, we attempted to adsorb cesium using ash waste ash. In this research, an experiment was conductedto prepare a glass tube filled with volcanic ash and flow cesium. The result reports that 99.8% of removal succeeded.

Gasification of Food Waste by Pyrolysis
Tokyo Metropolitan High School of Science and Technology
RINA Ooguchi, MARI Sawasaki, YUKA Nagasawa

Abstract

The amount of food waste discharged by Japan is 22 million tons per year. Fifteen million meals will be offered at the Tokyo Olympic Games and the Paralympics Gamesscheduled to be held in 2020. However, at the London Olympic Games, 22.43 million tons of food waste is discharged during the period. As in the London Olympics, it isexpected that a large amount of food waste will be discharged at the Tokyo Olympics and Paralympics. From this fact, before considering incineration, I thought that heatand energy can be used as food waste as unused energy and tried to convert food waste into combustible gas by gasifying it by thermal decomposition. We tried to convert
to flammable gas by thermal decomposition at low temperature by adding pyrolysis by adding additives to the simulated food waste but it was possible to suggest that theamount of methane increased as the generated combustible gas. We also report that we were able to demonstrate the possibility of energy conversion of food waste.

Causes of Research

Causes of Research

In the Great East Japan Earthquake that occurred in March 2011, it was hit by atsunami that we have never experienced before. In Fukushima prefecture nuclear
power plant was damaged by the tsunami, scattering radioactive material becamea problem (Fig.1).

Fig.1 Great East Japan Earthquake
However, there are things that are a problem at the same time as measuresagainst accidents at nuclear power plants. That is that groundwater flows into
the nuclear reactor building by about 300 tons a day, becoming new polluted
water containing highly concentrated radioactive material. When I was awareof this situation and thought that I could do something, I learned that the total
amount of ash fall in Kagoshima prefecture was 4.9 million tons in 2015, andcountermeasures such as damage to agricultural crops were urgent. Using this
volcanic ash in Kagoshima prefecture, I thought that after the Great East Japan
Earthquake, I thought I could handle contaminated water that is interfering withthe processing of nuclear power plants.

Research Method

We examined how cesium and strontium contained in contaminated water canbe removed efficiently. As contaminated water is generated by the flow ofgroundwater, we attempted a method to consider the flow of water and adsorb it
and remove radioactive substances (Fig.3).

Treat Contaminated Water with Volcanic Ash

In the research of Kyoto Prefecture University, it is reported that silicon has
the property of adsorbing cesium. Since the main component of volcanic ash issilicon, it was conceived that volcanic ash would adsorb radioactive materials
and be useful for contaminated water treatment. Cesium and strontium arecontained in contaminated water produced at the Fukushima Daiichi Nuclear
Power Station, but cesium can be treated in the septic tank, but various
treatments have been made with the treatment of strontium as a subject.
Currently, it is being processed by multiple purification facilities such as pollen
allergy removal equipment (ALPS) for the purpose of adsorption. Therefore, it
is relatively easy to obtain and tried contaminated water treatment using
volcanic ash, which is waste in Kagoshima. As a sample, strontium nitrate andcesium nitrate, which are nonradioactive substances, were subjected toadsorption tests as simulated radioactive substances (Fig.2).

The amount of food waste discharged by Japan is 22 million tons per year.
Food waste that was originally able to be eaten is 6.32 million tons per year.
These 6.3 million tons is equivalent to twice as much as 3.2 million tons of foodaid from the world. In addition, some of the food waste is used for fertilizer etc.,
but 90% is incinerated. Fifteen million meals will be offered at the Tokyo
Olympic Games and the Paralympic Games scheduled to be held in 2020.
However, at the London Olympics 22.43 million tons of food waste wasdischarged during the period. Like the London Olympic Games, it is expectedthat large quantities of food waste will be discharged at the Tokyo Olympic
Games and the Paralympic Games. From this fact, before thinking about
incineration, I thought that food waste could be used as heat and energy with
unused energy. We tried to convert food waste into combustible gas by gasifying
it by thermal decomposition (Fig.1).

A simulated sample was passed through a volcanic ash column, and asimulated sample that passed was quantitatively analyzed using an atomic
absorption spectrometer (SHIMADZU AA-6800) and a hollow cathode lamp(Cs) (HAMAMATSU PHOTONICS L-233-55 NB). Then, it was confirmed
whether the concentrations of cesium and strontium in the sample decreased(Fig. 4). In addition, pH change before and after the experiment was also
tracked (Fig. 5).

A. Experimental materials
In this study, as a simulated food waste, a cooked rice (Koshihikari from Miyagi
Prefecture) was artificially dried at 110 ° C for 24 hours. Molecular Sieves 4 A(1/16 Wako Pure Chemical Industries) was used as an additive. Experimental
conditions of this study are shown in Table 2.

B. Experimental method
The experimental apparatus used in this study is shown in Fig. 3. 20 g of asample was placed in a glass reactor, and in order to remove oxygen from thereactor in 60 minutes, nitrogen substitution was carried out. When additives wereused, 20 g of additives were mixed into the sample and placed in the reactor as a
mixture. Nitrogen gas was flowed at a flow rate of 50 mL / min. After purging
with nitrogen, the nitrogen gas was stopped and thermal decomposition
experiment was carried out. The sample part of the glass reactor was measured as
the decomposition temperature.

Research Method

Pyrolysis is generally carried out at 600 to 800 degrees, but it was carried out at
low temperature because it is highly used waste. In order to perform thermal
decomposition at low temperature, we tried to add more gas by adding additives.
Consider decomposing bonds at low temperature by adding additives.

an alkaline aqueous solution. The recovered gas was qualitatively andquantitatively analyzed by gas chromatography equipment.

Results and Discussion

Gas components were analyzed by gas chromatography (SHIMAZU GC-2014).
Analysis results are shown in Fig. 5 and Fig. 6.

Experimental Method

As a sample, volcanic ash (Tarumizu City, Kagoshima prefecture), cesium
nitrate (Wako Pure Chemical Industries), and strontium nitrate (pure chemicalindustry) are used. A solution prepared with 0.001 mol / L cesium nitrate aqueous
solution and 0.001 mol / L nitric acid strontium aqueous solution as simulated
contaminated water is used as a standard solution. In this study, only the result of
cesium nitrate is reported.
Experiment Procedure
STEP1
Feed 100 mL of simulated sample into the volcanic ash column.
STEP2
Collect the filtered simulated sample.
Flow again recovered simulated sample to a new volcanic ash column.
STEP3
STEP4
Repeat the operation from STEP 1 to STEP 4 three times.
STEP5
The filtered solution is quantitatively analyzed by atomic absorption
spectrometry.

Fig.4 Changes in cesium concentration
Fig.5 Observation of pH
As shown in Fig. 4, the cesium concentration could be decreased by
98.8%. It can be inferred that this is due to the adsorption effect on the volcanicash. Also, since the pH of the solution was kept almost constant, it isconsidered that there is no influence by pH.

Conclusion

In this study, we focused on the fact that silicon contained in volcanic ash
adsorbs cesium. As a result, 98.8% of the cesium concentration could be
adsorbed. This suggested that volcanic ash can contribute to the treatment ofcontaminated water discharged from Fukushima Daiichi Nuclear Power
Plant.
Acknowledgments
In starting this research, volcanic ash from Sakurajima was provided free ofcharge from Tarumizu City Hall in Kagoshima Prefecture.

A. Review of additives
Molecular sieves were used as additives. Molecular sieves used ascolumn-packing materials are porous and are used as adsorbents. Since it is an
artificial zeolite, a catalytic effect has been reported.
B. Review of molecular sieves
The pH of the molecular sieve 3A, 4A, 5A, and 13X was measured according to
JIS standard dissolution test.

* According to the dissolution test of JIS standard, sample was mixed with
distilled water = 3: 100, shaken at 200 rpm for 2 hours, and the pH was measured
with a pH meter (HORIBA pH METER D-51). Also, taking into consideration
the influence on the thermal decomposition depending on the size of the particle
size, after grinding, it was shaken by an automatic vibrator, and the particle size
was adjusted to 150 µm to obtain powder. In this study, we decided to use
Molecular Sieves 4A whose solution pH was the maximum value as an additive.

Fig.6 The proportion of methane
Compared with Condition I, Condition V decreased gas production amount.
However, it suggested that it should be increased as a ratio of the amount of
product gas. This is presumed to be an action due to the catalytic effect ofMolecular Sieves 4A. Further, in Condition V, since it was possible to make themethane content to the gas production amount 10% or more, it is inferred that
there is the optimum addition amount in the addition amount.

Conclusion

In this study, pyrolysis was carried out at low temperature by adding pyrolysis
by adding additives to simulated food waste and attempt was made to convert toflammable gas, but as shown in Figs. 5 and 6, the catalytic effect Suggesting an
increase in the amount of methane produced by the process. We were alsoable to demonstrate the potential for energy conversion of food waste.

Recovery of Tantalum from Tantalum
Capacitor by Pyrolysis Treatment
Tokyo Metropolitan High School of Science and Technology
SAKI Hachinohe, WAKANA Dodo

In recent years, the rapid consumption cycle of home appliances is conspicuous. Therefore, the electronic board is also discarded. A large amount of rare metals arecontained in this electronic substrate, and recycling thereof is desired. In this research, attempts were made to recycle tantalum capacitors, which are often used inelectronic substrates, by thermal decomposition treatment. Hydrotalcite, which is a magnesium-aluminum complex in which a tantalum capacitor is expected to have acatalytic effect, was added to perform thermal decomposition. By adding hydrotalcite, it was possible to remove the tantalum burned substance in the tantalum capacitor.

Tantalum is called rare metal, and it is considered policyful to ensure stablesupply among metals that are difficult to extract due to rare or abundant technicaland economic reasons. Tantalum is one of rare metals (31 kinds) and it is used asa capacitor of electronic equipment. In the future, demand is expected to grow,including mobile phones and PCs, and securing that is required.
In Japan, the so-called "urban mine" is abandoned with a large amount of usedelectric products containing rare metals. In addition, due to the enactment of the"Promotion of Recycling of Used Small Electronic Equipment etc." enacted in2012, tantalum and other recycling tend to be prioritized. Therefore, it is desired
to develop a new technique for efficiently separating and collecting resources
such as rare metals contained in electric devices and electronic components.

Tantalum Capacitor

It uses rare metal called tantalum for the capacitor element, it is smaller thanconventional capacitor and can obtain large capacity, so it is used in all kinds ofelectronic equipment including mobile phones. The calcined body of tantalum
occupies 43% of the total mass, and since the fired body contains a highconcentration of tantalum, recycling from products to be discarded is desired(Figs. 2 and 3).

Experiment

Previous research…
■Oxidation roasting: Oxidizing roasting at 450 ° C to 500 ° C.
■High Pressure Dissolution: Solubilize in a high-pressure vessel (20 atm) for 4 hours
with solvent (NMP) under K3PO4.

What is Hydrotalcite?

Hydrotalcite (HT) is an aluminum-magnesium complex (Fig. 4). It has been shown thatwhen anions are adsorbed, they have the property of changing to a structure called aninterlayer outer spherical complex (Figs. 5 and 6) If a sphere can be confirmed as shown in
Fig. 6, it can be inferred that anion has been adsorbed.

The mold resin of the tantalum
capacitor contains a halogen type
flame retardant such as bromine,
and it is generated as a gas during
processing. Also, the molding resin
has very high physical and chemical
stability (fig.3.).

I learned about the current situation of Sambu cedar that was produced ineastern Chiba prefecture (Fig. 1), which is a short distance from Tokyo (Fig. 2).
Sambu cedar has been produced since the Edo period, has been produced by aunique production method. However, Fomitiporia sp. has a disease called
Fuscoporia Punctata. Its prevalence rate has been reported to be over 85%.

Do not do special processing

Experimental Method
Material: 1 L of Water, 200 g of Cedar, Cotton fabric
Step 1 Pour the cedar chips and water in a pot and simmer for 30 minutes at
weak to medium heat.
Step 2 Remove the cedar. This is called a dye liquor.
Step 3 Stop the fire and dye it with cloth washed with water.
* Condition II, Condition III dyed what was processed in Step 3.
After the experiment, the dyeing solution before dyeing and after dyeing isqualitatively analyzed by GC-MS equipment, and the dyeing components are
examined.
Results and Discussion
The dye liquor was diluted 100-fold with ultrapure water and analyzed bycomparing the peaks obtained by Shimadzu GC-MS-QP2010ultr (GC / MS). The
main compounds were identified by GC / MS spectral library. The qualitative
analysis results are shown in Table 2.

B. Experimental Method

The experimental apparatus used in this study is shown in Fig. 7. A sample was placed ina metal reactor, and in order to remove oxygen from the reactor in 60 minutes, nitrogen
substitution was carried out. Nitrogen gas was flowed at a flow rate of 50 mL / min. After
purging with nitrogen, the nitrogen gas was stopped and thermal decomposition experiment
was carried out. The sample part of the metal reactor was measured as the decomposition
temperature.

Fig. 2 Sambu cedar
We went to fieldwork in Sanmu City, Chiba prefecture, and examined thepresent condition. Analyzing the current issues as what we can do, I thought
about the project image (Fig.3) that would lead to regional regeneration andforest regeneration. We attempted to find new value for what is considered to be
worthless for the purpose of treating the wood left in the forest.

Results and Discussion

Fig. 7 Experimental apparatus diagram

It was raised to 550 ° C at 5 ° C / min. Gas that passed through the cooling pipe wascondensed to produce oil and was collected in a recovery container. The no condensable
gas was collected in a gas pack via bubbling of an alkaline aqueous solution. Afterpyrolysis, analysis of thermal decomposition products (residue and gas) was carried out.
For the residue, the surface was observed with an energy dispersive X-ray analyzer (EDS).
Gas components were qualitatively and quantitatively analyzed by gas chromatographyequipment.

In this research, we aimed to recover tantalum by thermally decomposing tantalum
capacitor. In this study, it was possible to decompose the mold resin by addinghydrotalcite, so it was possible to take out tantalum relatively easily.

Pretreatment was carried out with soybean milk or milk whendyeing, but the coloring was not good. Unprocessed conditions wereclosest to pink (Fig. 6). Although no mordant is required, it can beinferred that the dye liquor itself acts as a mordant since the metalcomponent is detected from the qualitative analysis of the dye liquor(Table 2).

Conclusion

Fig. 9 Removed tantalum Fig. 10 EDS image of the residue
Tantalum could be removed from the tantalum capacitor by thermal decomposition
at 550 ° C. This is presumed to be due to the catalytic effect of hydrotalcite, which promoted
the decomposition of the mold resin (Fig. 8 and Fig. 9).

Further, hydrotalcite has an anion adsorption effect, it can be inferred that the generated
gas of halogens contained in the mold resin could be recovered as a residue.

Experimental Method
We examined how to dye colors that could not be established. There was areport that Sambu cedar could be dyed without using mordant. For that reason
we studied dyeing without special treatment. The experimental conditions areshown in Table 1.

The residue after thermal decomposition (Fig. 8) was mixed with distilled water 100 at aratio of 3 and stirred with a stirrer to recover tantalum. Also, EDS observed the surface of
HT. As bromine concentration rose to 31.5%, it was possible to recover bromine in theresidue. Moreover, it was possible to confirm the formation of spheres, which is acharacteristic when adsorbing anion.

Research Background
Japan is a forested power country where forests account for more than 70% of
the country's land. However, due to the decline in the timber resource utilization
rate of domestic timber, timber self-sufficiency rate is only around 30%. In
addition, the number of forests with unused materials left unattended isincreasing.

Fig. 1 Research Area

The sample is a mixed sample with 5 g of tantalum capacitor and 5 g of additive.
Table1 Experimental Condition

Fig.2. Component ratio of mold resin

Japanese forests exceed 70% of the country. However, at present, most of the forest resources tend not to be used for reasons such as price increases and talent shortages.
Chiba prefecture near Tokyo is no exception. In Chiba prefecture there is Sambu cedar that is produced 400 years ago. However, Sambu cedar has a widespread peculiar
disease and its value is significantly reduced. Therefore, many of the harvested Sambu cedar have been left in the forest as a residual forestland. As an anecdote of aforestry owner, Sambu cedar is said to have the ability to dye in pink. In this study, we attempted to stain pink with remaining material of the forestland that is considered
not worth.

Both of them have issues such as generation of toxic gas, plant cost, length ofprocessing time, etc. Therefore, it is required to recover tantalum by removing the moldresin without generating toxic gas under comparatively mild condition.
⬇
Hydrotalcite has an anion adsorption effect and catalytic effect, so it is added andthermally decomposed.

Abstract

Abstract

Introduction

Research on Utilization of Cedar as Unused Resource

Fig. 3 Project Image
From the fieldwork, it was found that it was the treatment of the forest residue
material as a matter to rush. Sanmu has an anecdote of "Cedar that stains inpink". Furthermore, although precedent cases have been reported, dyeing
methods have yet to be established. We decided to study the method of dyeing
pink using the remaining material of forest of Sambu cedar and to examine thecolor components.

Conclusion
It can be inferred that dyeing should be carried out as it is without pretreatment
or the like. Further, it can be inferred that it is not necessary to add a mordant
because the dye liquor contains a metal component.

Possibility of the slug and fungi mucus use
Sakura High School Akane WADA(2) Hiiragi AKIHO(2) Rei MATSUDA(2)Introduction

The slug mucus is difficult to remove
by washing and rubbing with water
when it attaches to hands. Throughthis experience, we think that it canbe used as glue in water. We tested
property of three kinds mucus : okra,
nameko, and slug.

 When slug’s mucus dry, its adhesion is increased.
 The adhesive strength of okra’s mucus and slug’s mucus became fragile
along with the length of time drying mucus naturally.
 Nameko’s mucus of adhesion is fragiler than that of other creatures.

・We stuck two pieces of paper together withmucus or glue like below illustration.

Motive and Outline
NATTO is one of Japanese traditional foods. It is known that its deliciousness varies by the amount of mixing. we had a question why its deliciousness
varied. So we thought “become delicious=the amount of amino acid increase” and mainly examined its comparison because NATTO contains amino acid.
First, We measured concentration of amino acid and understood that amino acid increased by mixing NATTO. Next, we experimented to examine why
amino acid increase by mixing. From results, we thought it wasn’t the effect of the enemies, but amino acids sticking to NATTO dissolved in stickiness.

That reason is that NATTO is shaved and amino acid in NATTO dissolved.
We want to experiment about self life of NATTO from how on.

Tokyo Metropolitan High School of Science and Technology

What is Iriomote island?
The island belongs to Okinawa, Japan

ABSTRACTIn this experiment, we explored to get rid of salt in seawater. We stirred it after mixing additives. The additives tested weremolecular sieve 3A, 4A, 5A, 13X, and hydrotalcite(Mg6Al2(CO3)(OH)16・4H2O).
We found that molecular sieves 4A and hydrotalcite adsorb the most chloride ions, and molecular sieve 4A can be reused.

I also learned that the nature is being destroyed because of the increased number of tourists.
As the number of tourist increases, the number of car accidents that kill the wild cat increases.
I think the Iriomote’s nature is Japan’s treasure. To protect Iriomote island, it is important tohave everyone know about the importance of this island.

Influence of Sidestream smoke on the rate of germination of Radish sprout.

2nd grade of Tokyo Metropolitan High School of Science and Technology

We visited Kota Kinabalu, Sabah, Malaysian Borneo in March, 2017 and did field research to know about the nature of Southeast Asia.
Borneo is the third-largest island in the world. There is a large tropical rain forest where lots of precious wild species live.

Purpose of our trip ① To know the current situation of DEFORESTATION

Kota Tachikawa & Ryota Masuda
Shibaura institute of technology Kashiwa high school (2nd grade)② To see the WILDLIFE SPECIES living in Borneo

Environmental Problems in Borneo

Consumption of “Vegetable Oil” in JapanThe Transition of Oil Palm Production Volume and Area

Do you think this is a natural forest？

In the following, Radish sprout and Broccoli sprout is shown as “Radish” and “Broccoli”.
Driving Question:
We often heard that cigarette’s smoke influenced the human body. Recently, it is said

https://www.env.go.jp/policy/hakusyo/h23/index.html

This “Oil Palm Plantation” is artificially createdby humans after destroying natural forest.

From WWF website

Oil Palm Plantation is increasing year by year.
Malaysia and Indonesia account for 85% of world productionof Oil Palm.

Why do people produce the oil palm so much?

“Palm Oil” and “Palm Kernel Oil” account for 27.5% of the
2.5 million tons of vegetable oil consumed in Japan.

💲💲The more they planted the Oil Palm,
the more they get money!💲💲

 They can produce the Oil Palm up to about 4t per hectare, while
Rapeseed Oil is produced up to 1t per hectare Once planted, they can keep high productivity for up to 40 years.

that sidestream smoke is more harmful to us than mainstream smoke. Then, we did anexperiment with interest in how much sidestream smoke would affect the plants thatcan not escape from the smoke.
Methodology:

Planting Trees - Mangrove Rehabilitation Project We joined “The Reforestation Project” of Sabah Forestry Department (SFD) which is the government agency in Malaysia andInternational Conference on Sustainable Mangrove Ecosystems (ISME)

We planted 2,500 propagules (seeds of mangrove) on the Disused Shrimp
Ponds or Deforested Area to revert back to the original forest.

We raised the seeds of radish without nutrition for 4 days. We used 3 g of radish seeds
and 1 g of broccoli seeds. We spread cotton in petri dish, add 20 mL of water and sow
sprout seeds all over.
We made 2 boxes of cardboad ,and raised sprouts in it with smoke and no smoke forControl. We changed the smoke every day and changed the water once every two days.
We found smoke of cigarette is heavier than air, so we put in the smoke from the top of

Discussion• Before we went to Borneo, we have already known about those environmental problems. BUT, we felt those are far from me. After this fieldresearch, we were shocked to find out that we were using a lot of None-eco-friendly products made in those plantations. So, we realized that
we are destroying the world forests indirectly and we took the habitat of creatures away.
• However, it is important for Malaysian to get money by producing and selling the Oil Palm to the developed countries. We also learned that
there are some facilities made with Oil Palm profits. It is difficult and complicated problem to enrich the human life while protecting thenature.
→ IN CONCLUTION, it is too difficult to remove the Oil Palm Plantation in Borneo, but we think it is important not to expand. For now, therate of the world Palm Oil consumption is increasing year by year. In order not to increase it anymore, it is also essential to have many
people know the current situation of the plantation. So, that’s why we are now introducing the threatened nature of Borneo. We strongly
want all of you to think about Borneo nature in your day-to-day life.

In Broccoli , There was no significant difference between smoke and Control in length
and weight of sprouts , It seems there was no influence by sidestream smoke.
In Radish, The germination rate was observed no significant change in MEBIUS (abrand of cigarette with a small amount of nicotine and tar.) And ECHO(with the nicotine
and the tar amount in the middle value), the germination rate was lower than Control
when adding sidestream smoke. From these two results, the germination rate is
influenced by the amount of nicotine and tar contained in sidestream smoke.

Consideration

By using agarose gel electrophoresis, marker size compared to thechloroplast rbcL gene of Ashiro Rindou gentian in the wildlife species andhorticultural species. Deduce the result from almost the same, andgrowth characteristics similar to those. Our height 28.5-think for 30 mthat is surrounded by sloping terrain, water accumulates and poorly
drained. For this reason, most likely is not suited to gentian.㻌

Future challenges

Why didn't follow herb garden, places an herb garden is well drained, I
guess quiet and gentian are difficult to grow in. From the experimental
results, instead of the wild species gentian horticultural species gentian
grown again examine the cultivation environment and then die. Want totry playing the wild species gentian, Funabashi-City in future.

Abstract

The anatomy of leaf blade, pitcher and lid epidermal characteristics of the genus Nepenthes (Nepenthaceae) in Thailand were investigated.

The samples were prepared by leaf epidermal peeling and clearing method, stained with 1% safranin in 70% ethanol. The results indicated that thesignificant leaf blade, pitcher and lid epidermal characteristics for some species delimitation are shapes of the epidermal cell, characteristics of anticlinal
cell wall and types and the distribution of trichome. In addition, the generalized epidermal characteristics in species studied are as follows: smooth
cuticle, types of the anomocytic stomata, types of the stellate trichomes and types of druses crystals.
Introduction

Objective

Genus Nepenthes, common name is Tropical Pitcher Plant. It has distribution
in the forest replacement, in the soil with low nutrient acid. Data from thestudy on the ecology and distribution of Nepenthes in Thailand (Soodjai etal. (2555)). The researching for Plant species group whom rare andendangered in 2012 identify that found Nepenthes are 7 native species and1 variety. There is currently no study on the anatomy of Nepenthes inThailand. In addition, the classification of Nepenthes plants is still
problematic because the most of the Nepenthes species produce 2 types ofpitcher. At a young age the pitcher is short, rather round, hanging down to
the ground, this pitcher is called lower pitcher. When the trunk began tolengthen. It creates a pot that is slimmer and can be conical, this pot is called
upper pitcher.That is the reasons why it is very confusing to classify.
That why we attend about the anatomy of Nepenthes should be studied
in order to share the information with other data. To help identify
Nepenthaceae family is clearer and more accurate.

To study epidermal tissue characteristics of blade,pitcher and lid of genus Nepenthes
for use as a taxonomic information.

MethodResult

The results reveal in fig.1-3, showing the comparisons of leaf, pitcher and lid epidermis of plants in genus Nepenthes. Leaf epidermal cells have

irregular, jigsaw and pole-like shape. Anticlinal wall are concave and wavy. Trichomes are branched peltate, hair and stellate with druse, raphide andprismatic crystal. The waxy zone on pitcher has concave and wavy anticlinal wall. Its trichomes are also branched peltate, hair and stellate. Epidermal
cells in digestive zone have irregular, jigsaw shape. Anticlinal wall are straight, concave and wavy Trichomes are branched peltate, hair and stellate withdruse, raphide and prismatic crystal. The lid’s cells have straight and concave anticlinal wall with branched peltate, hair and stellate trichome.

Phrae

Making of Mohom

Phrae Province is one of the most ancient
cities of Northern Thailand. Phrae wasestablished in 1371 B.E. by Phaya Pol. The
former name was "Pol Nakorn" , then changed
to "Wiang Ko Sai" which means "Silk Cloth".
Phrae is known as a peaceful city that has thelargest reserved teak forests in Thailand. It issurrounded with mountains, and located on thebanks of the Yom River. The distance from
Bangkok to Phrae is 555 kilometers. Phrae isalso famous of its natural-dyed fabrics called‘Mohom’Making of dyeing color

1.tie Homs into small bundles, soak them in pots or buckets for 72
hours. After 3 days, water will turn to dark green, take out the pieces of
Hom that don’t decay.

History of Mohom‘Mohom’ is the combination of ‘Mo’/mɔː/ and Hom /hɔːm/. Mo means pot,
and Hom is the name of a plant that gives indigo blue color. It is well-known
as natural-dyed clothes that has unique blue color.
Mohom originally came from Laotians (Thai Puan) and Thai Lue. Two
centuries ago, some of them moved to Tung Hong where became the biggest
marketplace of Mohom in later. Mohom was popular in laborer class, andbecame widespread because of its low price and its durability. It was usually
weaved with the traditional loom, and had plain style. Later, Mohom has
been adapted to be more fashionable to attract young customers, and the
dressmakers tend to buy complete clothes from factories instead of weavingby themselves. That makes the price of traditional weaving clothes go up sohigh. Moreover, there are many shops that use chemical dyeing color insteadof the natural one. However, natural dyeing color is still used widely since it
gives more beautiful color and doesn’t smell.
Nowadays, Mohom is noted as Phrae local identity. People usally wear
Mohom to work or to attend some festivals such as Songkran day. Many
schools have their student wear Mohom on Friday. Aside from clothing
products, Mohom can be found as keyrings, keycovers, pillows, bags, etc.

The soundbox is made from coconut shellthat is covered on the open front by cow
skin.

They saw u is held vertically and has two
silk strings that are played with a bow.

2.Dissolve lime, beat until
bubbles occur on the surface.
Then continue beating until the
bubbles disappear.

3.Filter the water to get Hom sedimentor leave it a night for sedimentation.

4.Pour lye into a huge pot (ratio of lye and Hom sediment is 2 L: 1 kg),
put all the mixture in( Hom sediment, tamarind juice, lime, Water fromwashing rice.) Stir until the mixture is well-mixed.

5.Dip the mixture and pour it down. Do it
every morning and evening for 3-5 days.
When blue bubbles occur on the surface
and don’t disappear , the mixture is readyto be used.

Introduction
Indonesia is one of the country with thehighest biodiversity in the world. It hasabundance of biomass that could bethoroughly
explored
especiallyforadvancedmaterial
researchandtechnology. One of biomass with highcellulose content, namely Imperata
cylindrica otherwise known as speargrass,is potentially used as a carbon source tosynthesize graphite and graphene.
Graphite is an allotrope of carbon withthe trigonal sp2 bonding, which iscomposed of series of stacked parallel layer
planes. Within each layer plane, the carbon
atom is bonded to three others withstrong covalent bond, forming a series ofcontinuous hexagons in what can beconsidered as an essentially infinite twodimensional molecule. While, much
weaker van der Waals bond exists between
each layer.

Goals

1. To compare the structure of graphite and graphene
oxide obtained from speargrass;
2. To determine the optimum temperature and holding
time of pyrolysis of speargrass to obtain graphite;
3. To compare the structure and morfology of graphene
oxide obtained via modified Hummers method.

Thermo Gravimetric-Differential Thermal Analysis

Materials Synthesis

SEM, XRD

Graphene is a single–atom thick sheet of
sp2 hybridized carbon atoms arranged in ahexagonal lattice. Graphene oxide isgraphene with the interruped aromatic
lattice by carboxylic (COOH) groups at theiredges, and also epoxides (C-O-C), alcohols(-OH), and ketone carbonyls (C=O) groups
on the basal planes.
Modified Hummers method is used tooxidize and exfoliate the graphite to obtaingraphene oksida (GO). Strong acidic
solution such as H2SO4 and HCl, also otherstrong oxidation agent, such as KMnO4 and
KNO3, are utilized in this process.

Materials Characterization

SEM, XRD

Analysis andConclusion

Graphene oxide (GO) is
synthesized using speargrass
obtained in Bandung-WestJava as the carbon source.
After dried for a while in theoven at 600C, the speargrassis converted into graphite via
pyrolysis method. Previously,
the temperature of pyrolysis
is determined by the TG-DTA
against the speargrass under
an inert gas, Argon. Then theobtainedgraphiteisconverted into GO via achemical exfoliation method,
modified Hummers.
Then, the graphite and GO
variations were characterizedusing XRD, obtained peak at
2θ ≈ 26.5o, 43o and 45o whichassigned to (002), (100) and(001) graphite and GO planes
respectively. SEM image ofgraphite and GO showed theporous morphology of the
carbon. SEM image of GO
also confirmed the peaks
obtained from XRD .

Conclusion
1. Amorphous graphite has been obtained via pyrolysisof spear grass. Graphite partially converted into GO
via modified Hummers method. SiO2 still exist on the
carbon obtained.
2. Among the variables chosen in this research, theoptimum temperature and holding time of pyrolisis
to obtain graphite from spear grass is 860oC and 4
hours, respectively.
3. Comparation between obtained GO :
 Z1 has higher degree of crystallinity than Z2

Recommendation
1. Crystallinity of the carbon might be increased by using
proper catalyst, such as Fe, Ni.
2. FTIR has to be done to confirm the XRD pattern, andalso to prove the functional groups of GO.
3. TEM and BET are needed to find the crystal orientationand the surface area of the carbon, respectively.

ABSTRACT
Soybean is the big three of the main food after rice and corn in Indonesia. One of the reasons that causes decreasing in soybean production is pathogenic fungi. Soilborne pathogenic fungi such as Fusarium
oxysporum, Rhizoctonia solani, and Phytium sp. have been known causing rotten and damage of soybean root. Indigenous microbes which are isolated from soil infected by pathogenic fungi have beenrecognized having important role in suppression the disease. Rhizosphere actinomycetes is good candidate for bioprotectant because of its large amount in soil and broad range of bioactive compound. Previous
research resulted 20 rhizosphere actinomycetes isolates from soybean plant which are potential as growth promotor. This research aims to analyze the antagonism activity of rhizosphere actinomycetes isolates
toward three pathogenic fungi. Two isolates coded ARK 92 and ARK 94 show the antagonism activity toward three pathogenic fungi by dual culture method. Hypersensitivity test was used to convince theability of two isolates as bioprotectant. The test showed there was no necrosis in tobacco leaves caused by isolates. This research proved the rhizosphere actinomycetes can be bioprotectant toward pathogenic
fungi on soybean plant.

THAI PERFORMING ARTSMO LAM

KHON

Khon is Thailand’s classical, high art form of performancethat dates back to the Ayutthaya era in Thai history. Khon isa mask dance drama in which the dancers wear masks andcarry weapons while dancing to the accompaniment of So(Thai fiddle) and other musical instruments.
Khon performance can be presented in various occasions,for example, during religious ceremonies such as thefuneral ceremonies of royalty, dignitaries or well-respected
persons.
Khon integrates elements of several art forms into an
artistic whole. In addition to its artistic value, Khon also
provides food for thought, maxims, morals and ethicalvalues that the viewers can apply in their daily life.

Mo Lam is the traditional art of singing folk songs andperforming folk spectacles of the Northeastern people.
Mo Lam is a narrative singing–singing about folk or
religious stories. The verses are accompanied by a khaen (akind of reed mouth organ). The stories are taken fromliterature, for example, Karaket, Sinchai tales from the Jataka
tales (tales from the Jataka or Buddhist Sacred Scriptures).
Mo Lam serves the community’s way of life and has
significant entertainment value to the community. It is therepository of stories, adages, wisdom and philosophy of thenortheastern communities that have passed down throughgenerations.

NANG
TALUNG

Nang Talung is a folk shadow puppet spectacle of thesouthern region of Thailand. It is a very popular kind ofentertainment.
Besides its entertaining value, Nang Talung’s lasting
popularity from the past to the present also rests on the
sharp wit of the puppeteer who comments on theprevailing social occurrences and happenings throughthe puppets. This reflects the character of the southernpeople who are keen on following social and politicaldevelopment and occurrences in the nation. Nang
Talung has therefore been a part of the social andcultural landscape of the southern people throughout
the ages.

HUN
KRABOK

Hun Krabok originated in the reign of King Rama V byadapting the Chinese puppet theatre from Hainan.
The bamboo puppet theatre originated in the northern
provinces of Sukhothai, Uttaradit, and Nakhon Sawan.
Bamboo puppet presentation imitates the Lakhon Ram(dance drama) by adapting the human dance movements tosuit the puppets. The basic dance movements for the puppet
show are: Klom Na, Krathop Changwa, Thaeng Mue, Ti Bot
and Ram Phleng. The puppeteers must practice these
movements until they are highly skilled. They must alsodeliver the dialogue. The clowns help progress the story andmake it lively and fun to watch.

Realizations

Most high school students in the classhadn’t seen their own DNA . So ,they hadvery good impression about the experienceof observing their own DNA. （→）
It was so difficult to teach a class to highschool students who spoke other language
for us. In the preparation step,we had manydifficulties that we suggested how to tell ina straightforward manner and teach a classmerrily. However, we could teach a class toThai high school students barely and get
confidence. Above all, we enjoyedcommunicating with high school students
very much.

・We need to improve English skill in order to speak easily
and understandably.
・A few steps were a little hard for them. (e.g. The steps ofprotease.) It might be good to explain carefully and takelonger time on difficult topics.

ObjectWhat I learned about Thai traditional
dance (Lakhon ram) was impressive

Japanese culture class

Lesson『See your own DNA』

What can we do to improve

・Give some task to figure out what they are doing.

Impression

They enjouedplaying Origami
and Kendama.
And, they were very pleased with
their own name of Kanji.

THAILAND CULTURE
Both Mahidol university and Kasesart
university welcomed warmly.
We were taught how to make thaitraditional dishes.
Some dishes of Thai were
spicy for us, but we found that
there are many delicious
dishes in Thai.
In the class of Thai dance, we wore
nice custume, and danced pleasantlywith music pecular to Thai.

SCIENCE CLASS
We gare lesson of science at twohigh schools.
The theme is “See your own
DNA”, the experiment is to takeout cells which is in cheek.
We have prepared hard before
departure, and then tried tomake class which is easy tounderstand and enjoyable.
The students of highschool
gave us impressions.
They said, “Teachers are kind.”,“It’s the first time to see my own
DNA.” and so on.
We were nervous because wetaught in English, but we could
finish without incident.

SIGHTSEEING
The students of university took us
some tourist spots after the class ofexperiment and holiday.
We were surprised at the buildings wehave never seen before.
Especially, the lying statue of gold was
bigger than we imagined.
Also, the prices of thai is different fromthat of Japan, so webought a lot ofsouvenirs.
Every spot andbuilding became
precious memories
for us.

FINISHED THE
TWINCLEAt first, we had some anxiety about twincle program.
However, thanks to twincle member, twincle office, andteachers and students in Thailand, we spent enjoyable and fulldays.
This experience will make us more grow up.
I’d like to appreciate everyone. We love Thailand !!

We wonder why the difference is born. So we research it.

・Gathering data & Discussion
・Modern time makes the Seishun?
In premodern:Rite of passage makes children an adult
In modern : Everyone needs knowledges to an adult.

The time is Moratorium by Erikson. He said
there are Moratorium man. It is that young people
who want not to became an adult.
Also, he said that adolescence is to be able toestablish identity or to diffusion of identity.
What is to diffusion of identity?
For example, it is occurred by to loss your dream, toreceive the reality shock and over self-conscious.
In a short…. Utu and Neet!!
So, It is important to establish identity.

Kokubun High School

Think Globally, Act Locally
ESD in Kokubun High School is based on three main points.

1. International Understanding
School Trip in Taiwan, Interact with students from other countries or Meros
Language School

2. Community Involvement
Local Music Festival, Experience as a teacher at elementary school

3. Environmental Survey
Survey of water quality in Kokubun-river

We must conflict to establish identity.
Conflict is the depth of the frustration andinferiority complex that modern ego.
The Modern ego is the Meiji era`s popular phrase.
The people who make the word is said Souseki
Natume and Ougai Mori. His novel, Sanshirou andSeinen, make the vision of Seinen.
The vision affect many people, for example Osamu
Dazai and Hideo Kobayashi.

・Seishun is affected by Mass media?

・questionnaire
We take questionnaire in 2017 and we get 103 data.
53 female and 49 man. Age 10 is 81, age20 is 6, age

Discussion about this problem in Japan                   (▲…partial)

In 2000 and 2010, Cabinet discussed this actively, however they didn’t come up with a concrete proposal. Moreover, few arguments
are held, so the problem remains a deadlock.

●Consideration
I find that many foreigners settle in Japan, and they are troubled by not being able to participate in politics. They cannot express
their own will about politics. I think it is profitable for not only the foreigners and but also Japanese people. Of course, I don’t saythat all settling foreigners should be given the right, because some can vote for not Japan but only themselves or their mothers
countries. In my opinion, only those who have sound idea on improvement in Japan, and the future of Japan should participate inJapanese politics. (for example, those who has been living for a specified period of time and hasn’t committed a crime should.)
The world has been globalized, so “Times” when it matters whether you hold Japanese nationality is changing.

<What the table shows>Ghana chocolate is cheap and sells well.”The cheaper, the more sales?” Not necessarily, since Frappuccino, rather expensive, sells well.That is, quality issometimes more important than the price.Further, expensive fair-trade chocolate seems more justifiable than expensive Starbucks Frappuccino.
Then why the sales volume of Fair trade products are not so good?
The sales of Ghana chocolate went up rapidly because of its red package. Meanwhile, Starbucks Frappuccino has the transparent cup (with a logo) through which
the colorful content can be seen. Youngsters find the design so “cute!” and, every time the company makes up a new line up, they would love to upload its photos
on the SNS.
From this, it seems there are two differences between fair-trade chocolate and Ghana chocolate (or Starbucks Frappuccino).

I really do not want to recommend all these products (since they will not be “my own”). Atelier Likha, a Japanese NGO in the Philippines and where I served as avolunteer, produces a nice book cover, and it is my real favorite. Thus, there are already so many good-design fair trade products. The next step is to consider how
to make those fair trade products better known. Since my mother is selling fair trade products, I often have fair trade chocolates, cocoa, jam and curry powder; andI also use fair trade commuter’s purse.
I know there are students who make research into fair trade and made their “advertisements” in their social study class.I do think they are interested in fair trade;then I would like to ask them: “are you spreading the idea of fair trade after knowing actually eating or trying fair trade products to know them better?”
You know, fair trade products are really tasty. They are cute. And they have such a high quality.
Of course the reason why we should spread the concept of fair trade is precisely their fairness-orientation. If that is everything, however, youngsters would
eventually avoid going for fair trade products. “Because they are tasty”, “and because they are fashionable”: I hope to introduce fair trade products for thesereasons.
One of the tools for me in this context is using social network service (SNS).

1DVKHTXLOLEULXPDFRPELQDWLRQRIVWUDWHJ\DOOSOD\HUV<How to improve the concept of fair trade>

Some companies engage in fair trade activities since they are concerned with their own public image or reputation. In Japan, that sort of “abusing the image of fairtrade” might not be so common, but in other countries where fair trade business is common, such kind of abuse is happening, I hear.
Not a few people might be interested in fair trade but they might think “is this information on fair trade really trustworthy?” For the benefit of those people,
companies should clearly indicate to consumers how their fair trade enabled some children to go to school, or made changes in the income level<Our approach>

We introduced fair trade products on the occasion of school cultural festivals. We displayed those fair trade products in a hallway and not in a classroom, so thateveryone who passes by can have a look at them.
We sold fair trade chocolates (800 pieces through two days.) When people buy those products, we also explained what fair trade is.
Then even after the festival, those who did not purchase the displayed fair trade items might later think: “oh this a fair trade product, which I saw in the cultural
festival!”
We noticed some points through this project. Especially, fair trade products are made for women, so those are less attractive for men than women. (As you can see
products above.) So we want our school to keep this project as an annual event in light of our own experience.

Flooding

Hurricane Irma struck the Caribbean,
and many of the island's residents
were forced to leave. Many strong
and large hurricanes occured innothern atlantic on end.

Heavey rains brought severe
flooding to India, Sourthern Asia.
Millions were affected and morethan 1200 were killed.

Torrential rain in northern Kyushu region in July 2017

Droughts

Major Heatwaves

More than 6.2 million people are
currently facing food insecurity andlack of clean water. It is because ofrivers that are drying up and recent
years with little rain in Somalia.

Wildfires occured a lot in Europe andthe U.S. due to dreadful heatwaves.
Reserachers estimate that 74% of the
global population will experience morethan 20 days of "deadly heat" by 2100.

As an approach to climate change, The Paris Agreement has been in force since the 4th ofNovember 2016. It is the agreement within the UNFCC (United Nations Framework Convention
on Climate Change). 195 UNFCCC members have signed the agreement, and 173 have become
part of it. It aims to:(a) Not let the global temperature rise any more than 2 °C of the pre-industrial level, and try tolimit global temperature to rise no more than 1.5 °C of the pre-industrial level, recognizingthat this would significantly reduce the risks and impacts of climate change;(b) Increase the ability to adapt to the adverse impacts of climate change and foster climate
resilience and low greenhouse gas emissions development, in a manner that does notthreaten food production; and(c) Make finance flows consistent with a pathway towards low greenhouse gas emissions andclimate-resilient development.

We performed panel discussions eight times in LHR this year. The purpose of a panel discussion is todevelop our own ideas by exchanging opinions with each other who have different considerations. We
choose our theme among these five topics. 1 group (7 members) will decide each role (1 Chairperson,
5 Panelist, 1 Minute Taker). After that, all the members make opinion papers for preparation.
This year’ｓ themes were: ①Globalization and Anti-globalism, ②Active learning, ③Heart transplant,④Global warming, ⑤Elections of Japan

A “Panel Discussion” is a system where some panel
members discuss with the chairperson, then the audiencetakes part in the discussion after hearing them.
Our goal is not only to make conclusions but also tolearn how to have a discussion.

At Funabashi Toyotomi High School, members of the student government and the JRC-UNESCO Club are
mainly working every day for our core objectives of local interaction and environmental issues as UNESCO
member school. For the local interaction, the members participate volunteer activities for about 30 times
throughout the year by using their summer vacation.

The alphabet is classified as a phonogram which
expresses a phoneme itself and it is arranged in a
traditional arrangement.
Usually, Latin alphabet is called “alphabet” inparticular, but alphabet shows character list, so
there are various kinds.

Kinds of alphabet
・English alphabet
・Spanish alphabet
・German alphabet
・Polish alphabet

Accurate information on the history of hieroglyphs andSinai characters has not been elucidated and linguists
have published a number of hypotheses.
B.C. 1000 Beginning, Phoenicians living in North Africa
advanced into the Mediterranean world, so by this way,
the Phoenician characters they used were transmitted to
the Greeks. Then Greeks made Greek charactersborrowing Phoenician characters.
In the 7th century B.C., the Latin who lived on the Italianpeninsula took characters from Etruscans and Greeks
and made Latin characters.
The old English that is the source of the English alphabet
started with Anglo-Saxons bringing Rune characters into
England around the 5th century, mixed with the Latin
letters brought in by the Christian missionaries aroundthe 7th century.
And they changed to the current Latin characters.

The English alphabet changed as follows.

With foreign students

We talked about what each school have done

xchangeas an UNESCO school.

Disaster prevention concert[Abstract]

How much do you know about Yukata? Maybe many ofyou don’t know well about its history, how to wear Yukata,when to wear Yukata and so on. Actually, we were one ofthem. Today we’d like to report what we studied about
Yukata.

We interacted with foreign school students

We invited Argentian guitarist and held afrom Melos Gakuin, Japanese language school concert at our school and enjoyed sessions withthrough classes.

Volunteer

the brass band club there.

And more

We joined community events and help management. We are doing plastic bottle caps collection
campaign. We are doing it to exchange for vaccine. That will help a charitableorganization give the vaccine to children. We clean school routes as a volunteer.
We pick up garbage on the school routes.

2016－2017 About our research

Chiba Prefectural School for the visually impaired

Research subject：
Curriculum according to the educational needs for each student

Research theme：
We examine the contents of learning students with visual impairments experience foreign cultures anddeepen exchanges with utilizing ICT and so on. We research the ways to send actively and to be necessary
for their improving language and communication skills. Also, we will verify the way of education that can
respond to globalization.
The reason：
When students with information disability participate in society and get more information and send out itfrom themselves, ICT is an effective means.
And, to send their own thoughts actively for others with different cultures is based on "self-understanding""regional understanding" as well as "challenging spirit" and "toughness to overcome difficulty". In order toacquire the ability to respond to a keen society by globalization rapidly, it is necessary to utilize highly
convenient ICT, accumulate highly versatile practical examples such as educational content and support
method.
Expected result：(1) While deepening understanding of different cultures, we can respect others.and enhance communication
skills to collaborate.
(2) By utilizing ICT tools which are presently highly versatile, and verifying the effect, consolidation of their
examples can be a guide for our domestic weak-eyed education etc.

Relationship between human character traits andacademics ability(1)Motive

We are interested in what kind of students are clever..
(2)Investigation
We distribute questionnaire for 5classes which chose random and get theanswers these questions.
・GTZ・Brothers and sisters configuration
・What are you often do at the home・character traits
・Sports experience yes/no
Survey persons : 125 persons(3) Forecast
The positive are clever.
The first child is clever because they have a sincere.
The person who have a sports experience is a clever because they are patient.
(4)Result>The more clever the more negative.
>The more stupid the more positive.

>Oldest is most clever.

>Sports are not relevant to academic ability.

English lessons with Skype with ALT

We are planning to continue exchanging with e-mail and skype in the future.
Those who can cooperate, please call out.
Thank you.

(5)Difference between forecast and result
We have thought that the positive are cleverer than the negative. However,many clever people have negative aspects.
Playing sports makes people patient so we thought they can make use of it
for studying. However, whether people play sport or not, it dose not matterto their academic ability.
(6)Regret points
The number of people surveyed is small.
The kind of personality choice is small.
(7)Summery
The reasons why the clever tend to be negative is because they think they arestill inferior and study more than other people.

OTHER EXAMPLES of whatsurprised foreigners.
・THE TRANSPORTATION SYSTEM isvery developed. Foreigners are
surprised that trains always arrive ontime.
This is why we can make plans ingreater detail.
But, Japanese train transfer is very
difficult. So tourist need to ask or
research deeply.
・OMIYAGE are more than souvenirs.
The term “omiyage” is oftentranslated as “souvenir” in English ,but omiyage are much more thanthat. Unlike souvenirs, which people
often buy for themselves, omiyage aresomething people bring back for theirfriends, families and co-workers aftera trip.

OutcomePracticing ESD gives us a sense of exaltation in a totally diﬀerent way from how we feel from conventional classes.
ESD provides invaluable opportunities for students to feel and think about our community and society,which are
only available outside the classroom. Through the program,many students get start to think “what can we do for
our society?” and “how can we contribute to our society?” as they develop a greater sense of responsibility as amember of the society, as well as awareness of current problems in the society.

We learn about Japanese culture because
we believe that it is important to know ourown before we learn about others.
