Abstract
It is said that Japanese voting rate is the lowest recently. So we sent out a questionnaire about an election to students.
According to the survey, the cause of this election problem was that there was an increase in distrust in politics andstudents did not understand the value of voting. We found solutions that students should practice elections at school andyoung politicians of the reform group come into being.

２－４ Runa Maruyama

Rika Mizunuma

Today, it is said that passive smoking is harmful to our bodies. It can be described that smoking area at Maebashi
station is open and there is a high risk of passive smoking. To address this problem, we considered some partitions
to change the airflow and experimented to investigate their effect. We concluded that it is the best to use twopartitions, one with holes at the top and one with holes at the bottom.

1. Introduction
We examined the case where
the wind was blowing from the
west.

We

hypothesizedthatpartitions could prevent airflow
fromflowingsideways

4. Resultandencourage it to rise. Also, we
thought that the effect could be
increased by making holes and devising their shapes.

2. Research
1. We called JT.
・ It is good to promote
the rise of smoke.
・Both intake and exhaust are important.
2. We looked up examples and standards of partition.

◎…Promote the rise of the airflow.

《Standards》〇…Change the airflow but scatter the smoke.

・A certain height (2~3m)

×…Do not change the airflow at all.

・A gap at the bottom for air supply(10~20cm)

etc.

5. Discussion《Examples》
・ Standing two partitions prevents smoke fromscattering more than one.
・When we make a hole in the windward partition at
the bottom and a hole in the leeward partition at thetop, the smoke rises most and prevented from filling.
・Too high…The smoke spreads laterally.

3. Experiment
1. With incense smoke, we visualized the airflow andreproduced cigarette smoke to investigate how
partitions work, ventilating the area.
2. We did a similar experiment using two that worked
well in the previous one.

Too low … The smoke easily closes over the partition.
⇒It would be better to find the optimum height witha cigarette and a full-scale partition.

Watching Videos of English Words
２－１ ９ Nakamura Arisa Nakamura Ayana

Abstract
The Wernicke’ center of the brain, which processes voice information, is said to be activated by listening to voice
at high speed. Subjects were divided into five groups according to speed, and each group was allowed to watch thevideo only once at the specified speed. Then compared the score difference between the test before and after
watching the video. As a result, the slower the viewing speed, the larger the score difference.

1. Introduction

The tendencies of image color that people have for fruits
and the reason
2－1 Group １１ : Ikuta Otoka、 Suto Rikako,

Abstract

They were investigated that the relationshipbetween the colors that people imagine for fruits
and the frequencies or things that they think of.
Besides, the reasons of the selections and what
they came up to mind were surveyed.

Takakusaki Miho

Introduction

Fruits are the ones that everyone knows and thoseare bright and impressive. We wanted to know theimage colors associated with fruits and the reasonsfor them.

Methods・Research

Taking into consideration the results of thetentative research and the season of the fruits(because it was thought to have relation to thefrequency of seeing the fruit), three fruits,
apples ,bananas, and peaches were listed, andconducted a questionnaire survey. The target is
42 people of 2-1. (Figure1, 2)
For each fruit, the following was surveyed.

1, The first thing that comes to mind
2, Frequency of viewing
3, What you see

The common tendency
among apples, bananas, andpeaches was that they had
different brightness andchroma, but they accounted
for the overwhelming majority

in hue.
Apples : It can be said that the image color of apples is influenced by the color of their appearance andthe imppressinon such as energetic, bright, and leader.
Bananas : The image color of bananas is influenced by the outside color and the creatures that eatbananas themselves.
Peaches : It can be said that the image color of peaches is influenced by the color of the fruit itself andthe soft and cute image.

1. Abstract
Music can change heart rate. To know which condition of music affects heart rate, the experiment was conducted. In theexperiment, subjects measured heart rate before and after listening to the music whose tempo(❶), beat(❷) and key(❸)
was changed. As a result, faster tempo than the one at rest increase the heart rate most.

2. Introduction

5. Results

We want to know how emotions and tensions change bylistening to music. For example, when we listen to musicwith a good beat, our tensions go up. We replaced it witha change in heart rate to express emotions and tensions
as concrete numbers.

The Connection between Expression and Feeling
2 年１組

Saaya Konno

Hinano Saito

Abstract
We conducted this study to learn about the connection between facial expressions and emotions.
We hypothesized that smiling expressions brighten the mood and make the video interesting.
However, the results were not as good as hypothesis. The reason is thought to be that the smileand serious expression could not be completely reproduced. It is also believed that the reason isthat the videos were not viewed one by one.
1, Introduction

2. Methods/Research(1)Purpose
The theme is because we wanted to know
about the effect of smile.
(2)Hypothesis
An experiment reported in the July 2008 issue of
Nature Neuroscience by a group of researchers
from Dr. Saskind at the University of Toronto. When
we made the subjects express “fear”
and“loathing” we recorded the physical changes when
they actually felt ”fear” and ”loathing”. So, we
thought it would be more interesting than whenpeople saw the joke with a smile.

・16 subjects were shown a video A and a video B.
The 2 videos are the same comedian and have asimilar composition.
① 8 of the 16 people were shown video A while
holding disposable chopsticks sideways in theirmouth to make a smile.

3. ResultA

The score of the fun of comedy was almost the same
whether it was seen with a smile or a serious look.
From this, it can be think the facial expression you
make does not affect the way you feel funny. “Also,
the reason why “”It is more interesting to watch avideo with a smile “”was not obtained” It is expectedthat the smile could not be completely reproducedwith disposable chopsticks. It is also thought that thecause of each experiment is that subjects did not beshown the video one by one.

・It was found that the soft sound peculiar to the Japanese language gave the impression that theconnection and separation between words were ambiguous.
・It was found that Japanese is related to the mother tongue.
・Japanese are more accustomed to hearing Japanese than English, so they can understand themeaning of the lyrics in Japanese and the scene comes to mind. Therefore
many people feel that Japanese is more comfortable.

Transition of Human Thought~Are “dictators” absolute evil? ~Group13 Hanana Sekiguchi Rina Iino Chiharu Shimizu

1. Abstract“Dictators” are often had the strong negative images. But in real, they not necessarily govern people
by their region of terror. There were some dictatorships which done when they had no choice but had
to do. We researched the image-change to them by our presentation.

2. The object of this research
To improve intuitive minus image head for “dictators”.

3. Hypothesis and word’s definition
Most of the people have minus images to “dictators”. The positive answers to questionnaire will
increase after the presentation by us.
“Dictators” of this research refer to “persons who gain control over all rights of management in theirhands”.

4. The way of research(1) The provisional research
Take questionnaires to our classmates. The following is the contents.

Q1. Who comes to mind when you hear “a dictator”?
Q2. Write down why they hit.

(2) The main research①

Take questionnaires to eight of our subjects. The following is the contents.

Q1. Write down your images to the “dictators”.
Q2. Why do you think so?
②

Make a presentation about Adolf Hitler with the PowerPoint we made.

③

Take questionnaires again.

Q3. Write your images to the “dictators” if you changed your mind after our presentation.

5. Result- Images to the “dictators”
Before the presentation: People who take control of a people or speech, have greed for gold andpower or detestation of people. They are strong, evil and scary.
Indication of the subjects before our presentation were abstract as a whole.

After the presentation: Hitler may have not been absolute evil since to establish a dictatorship
could be the best way for German government at that time. Hitler tried to survive as well as people
did. Racism is bad.
Almost replies turned concreate because of answering just after the presentation. The point of all
the subjects were that in addition to their previous answers they had positive images than before.

6. Discussion
Therefore, the presentation cannot change all of the negative thought to the “dictators” perfectly. We
had better take questionnaires before making a presentation that focus on one dictator, for example,
Hitler or Stalin.

To reduce your smartphone usage time by 25% or more～compare the weekly average～
2-3 Group9

Onai Yurika Shinoda Yui Masuda Yuko

Abstract
We found four methods to reduce wasted smartphone usage time, and examined how each method changes smartphone
usage time. The biggest decrease was 27.3% on average when the 30 minutes limit was applied to all apps.

Introduction

Consideration

We wanted to find a more practical way to reduce oursmartphone usage time in order to reduce the amount oftime we spend using our smartphone and spend that time
improving our abilities.

The average usage time of Grayscale has decreased themost in the pre-verification, but has increased in theverification. Moreover, 9 people answered that it was
impossible to use Grayscale for a long time

Methods
1. Make the screen black and white(hereinafter referred to as Grayscale)
2. Limit 30 minutes to all apps
3. Set the language setting to Arabic
4. Turn off the power every time you use
・Compare the average usage time per week with eachmethod and when nothing is done.
・Conducted for 13 people in each method

Result(graph3)Also, the average usage time of Arabic has increased
compared to when nothing was done. It is presumed that
Arabic had no effect because the basic display was inJapanese, and many of the subjects viewed photos andvideos. Furthermore, Arabic instructions were sometimes
displayed, so 10 people said it was inconvenient.

(graph1)
Most reduced

30 minutes limit(graph4)
Therefore Grayscale and Arabic are not practical methods.

・30 minutes limit - Gray scale
・30 minutes limit - Arabic
・Power off - Arabic(graph2)
The number of lifts was also reduced by the method inwhich the usage time was reduced compared to whennothing was done.

Significant differences were confirmed for each of thesethree combinations.

We recommend 30 minutes limit to reduce yourusage time of smart phone.

Many words needed for the exams make us troubled, so we
decided to use puns in a week and studied how to remember
80% of that range. In order to obtain an easy-to-understandresults, short-term memory and long –term memory weredivided into two tests for each experiment. This study showedthat if you read aloud more than 2 laps a day×3 times a week,
you can remember 80%.

ⅰ) Divided students into 4 groups

2. Introductionⅲ) Take the first test

M.Yamabe・Group1 is 2 rounds×1time/day, group2 is 2 rounds×２
times/day, group3 is 2 rounds×3times/day, group4 is 2

ⅱ) Hand out the prints for memorization
・Have each group remember at a fixed number of times for
5 days.
... Spend two days without looking at the prints after the test

(1) Purpose
We became humanities students from the second grade,and since we have more subjects to memorize, so we
wanted to find an efficient way to remember.

(2) Hypothesisⅳ) Take the second test that is different from thefirst oneⅴ) Grade two tests and get the average score
・If the score of the first test is 90％ or more, it isconsidered as short-term memories.
・If the score of the second one is 80％ or more, it isregarded as long-term memories.

You will remember it if you say two laps three or moretimes a day. According to the book, it is desirable toremember say seven times a day.

How to put up an umbrella not to get wet our body or rucksack
2-5 group 8 Arai Yu Watanabe Riko

[Abstract]
Even with an umbrella, it is common to get rainwater on your body and rucksack. So,
using a model and a doll, we investigated the best way to hold an umbrella without
getting rainwater on the body and rucksack when the person is stationary and there
is no wind. In this experiment, it was found that if the umbrella is tilted 30 degrees tothe back side of the body when the vertical direction is 0 degrees, rainwater will not
splash on the body.

[Introduction](1)Objective
Since our bodies and rucksacks often get wet on
rainy days, we conducted an experiment with thegoal of finding the best inclination that would
keep us dry.
(2)Hypothesis
Based on the fact that I always tilt my umbrella
and get wet, I hypothesized that the umbrella
would not get wet the most when the axis of theumbrella was at 0 degrees, with the vertical
upward direction being 0 degrees.

8. A diagonal line is worth 0
points, a cross is worth 1
point, a triangle is worth 2
points, a circle is worth 3
points, and a double circle isworth 4 points. Add them up
for each angle to get the total of the rectangle,
the total of the body, and the total of the whole.

3. Put water detection sheets on both ankles,

The reason why 30 degrees was the least wet isthought to be because the umbrella did not
directly hit rectangle and the body was wellinside the umbrella.
From this experiment, we learned that in orderto keep the body and rucksack dry from the rain,
it is best to tilt the umbrella at 30 degrees.
However, due to time constraints, we were notable to conduct the experiment this time, taking
wind and movement into consideration. We
thought that if we changed these conditions, we
could get different results.

The relationship between Emotion and Sounds~Focus on the sound of the Earthquake Early Warning (EEW)~
2-6 group1 Rin Abe Kirari Uranaka

Abstract
It is an EEW that we almost always hear in the event of an earthquake. But we think many people feel discomfort when
they hear the sounds. So we decided to look into which factor makes it so.
Sound①Introduction≪Preliminary experiment≫

Five sounds were heard by 37 classmates. (Changed tempo, repetition, and tension note.)
From this, raising 2 semitone is the most unpleasant. Slow tempo causes variations in results. Changing the tension
note, but there was no significant change in the result.
≪Hypotheses≫
・The slower the tempo of the sound, the greater the discomfort.
・Tension notes are not relevant.
・Change the degree of uneasiness or discomfort that one feels depending on the tone.

Methods
Sound① is the same pitch, speed, and tone as the actual EEW.

All 17 subjects.

Methods/Research
In the tentative research, we first took the following
question.
・Do you think the Earthquake Early warming is scary?
・What kind of sound do you think you are scared of ?
As a result, 97.1% said they were afraid of the sound of
Earthquake Early Warming. It was found that D# wasused in the E.E.W and that the sound was intentionallyraised by a semitone.
Therefore, in the present study, we investigatedwhether that apply to all sounds.
In the first experiment, the familiar sound was changed
as follows :❶Normal ❷Semitone up

How to pedal a bicycle with a headwind faster

Kano Aoi

Nagaoka Narumi

Abstract
In Gunma, people sometimes must pedal a bicycle against the wind. We want to pedal a bicycle with a headwind
faster. Then, two experiments were carried out step by step. Ultimately, two ways to pedal a bicycle with a headwind
faster were found. One of the way is that strengthening the trunk of the body and pedaling a bicycle standing up
and the other of the way is that pedaling a bicycle in a forward leaning posture.

~Testing the suitable distance while having a conversation~
2-6 12 Mai Kaseda, Ayane Namekawa, Sakurako Nishi

Abstract

The word “Personal Space” is defined as “the distance from another person at which one feels comfortable whentalking to or being next to that other person.” So how far is exactly the suitable distance for us female high scholars to have a comfortable
conversation? We tested the personal space of the front and sides of the body by verifying the relationship levels of each group of subject.

Introduction
The year of the 2020 is mostly about the COVID-19 and experts have been keeping saying that people should stay 2m away from eachother which is now called the “social distance.” But when it comes to communication, most people think that 2m is too far and feels
uncomfortable. By doing two types of experiments, the suitable distance of communication will be clarified.

2-6 Nene Tanaka Wakana Miwa Nanaoka Wada

Abstract

Many people wear clothes to hide their body line because they have no confidence in their physical appearance. The aim of our study is to be able to feel much more confident about their bodyand to have the beautiful legs. So, we asked some questionnaires to define which aspect of the beautiful legs. And we tried to identify how to exercise for getting the beautiful legs. Throughthese experiments, we concluded that circumference of thigh, calf, and ankle at 9 : 7 : 4 ratio, length of heel to knee, knee to crotch at 14 : 13 ratio are the golden ratio of legs. Our study showedthat squat exercise was the most efficient way to acquire the beautiful legs.

(1) BackgroundSome people like to listen to music when studying.
Listening to music brings us many benefits instudying, for example, it enables us to cut off outsidenoise and to keep awake. However, on the other
hand, some people have the opinion that listening tomusic while studying is not good because they singand cannot concentrate on their studies.
(2) Premise
In investigating which is better for studying,listening to music or not, it is clear that listening tomusic is not suitable for learning memorization
subjects because of the lyrics. That is why the mathtests were used in the research to maximize thebenefits of listening to music.
(3) Purpose
To find out which of the two, listening to music andwithout music, has more correct answers and more
answers when solving math tests.
(4) Hypothesis
There are more correct answers and more answers
when not listening to music than when listening tomusic. The rationale forthis is that when we

1. Introduction

NO music・Correct answers
When solving a math test, there were more correct
answers when listening to music than when notlistening. However, since the number of correct
answers per person was only about 0.18, it could besaid that the result was almost the same with orwithout music.
・Answers
When solving a math test, there were more
answers when listening to music than when notlistening. However, since the number of answers perperson was only about 0.15, it could be said that theresult was almost the same with or without music.
・Other
The number of correct answers and the number ofanswers was overwhelmingly larger when the sametest was solved a second time after a month.

4. Discussion
・ From the result that the number of correct
answers is large when listening to music than when
not listening to music, it can be seen that music does
not lack concentration when solving math tests.
・From the result that the number of answers islarger when listening to music than when notlistening to music, it can be seen that listening tomusic while studying math can study more
efficiently.
・ From the result that the total score isoverwhelmingly higher when solved the second time,
the above two considerations are not always correct.

2-7 16st team Ogino Hikaru Fudo Rina
Abstract :This study shows the connection between exam score and a clock.
1 Introduction

・Back ground Purpose
The subject is immediate problem because
high school students take a lot of exams. The
result actually can help us take exams.
・Hypothesis
According to previous studies the faster a clock
ticks, the better efficiency subject work. Thisdata is interpreted a clock as pacemaker. The
situation where there is not a clock is the sameas where there is. That is shaken the pace so thepoint decline.

① The number of times the mean value ofGroupA was larger than that of GroupB was
three times in five times. In short, theprobability of it was 60%.
② The number of times median of GroupA waslarger than that of GroupB was four times infive times. In short, the probability of it was
80%.
③ The number of times the mean value ofGroupA was over 1point larger than that ofGroupB was three times.
④ The number of times the mean value ofGroupB was over 1point larger than that ofGroupA was no times.
⑤ Discussion ③ , ④ means there was narrowmargin when the mean value of GroupB waslarger than that of GroupA.
(The margin of median is considered that itmeans nothing because it is certainly
multiple of 0.5 point.)

2 Method/Research・Subject: 2-7 36 persons (Half of subject looks
at a clock and the others do not look at a clock.
