all of the yogurts have a significant difference(if p≦0.05,it has a significant difference）

Cremoris FC※each yogurt does not have the same number of bacteria◎My hypothesis is Bulgaria bacteria andThermophilus bacteria will increase the most whenmixed with natto bacilli.
Why? ;Symbiotic action between Bulgaria bacteria
and Thermophilus bacteria
・they make each other increase even without
natto bacilli, so with natto bacilli they could
increase even more.

２ Experiment

only yogurt＜natto bacilli＞

the number of colonies＜lactic acid bacteria＞＜Material＞ ・yogurt・・・(a),(b),(c) each ３ｇ
・natto ９ｇ（３ｇ×３）①make
MRS medium＜Process＞②dilute yogurt×105③mix natto 3g and distilled water 30g④dilute natto water(③)×107⑤add only diluted yogurt on MRS mediumor
add diluted yogurt and natto water on it⑥culture 37℃ for 3 days
⑦count colonies
This experiment was done three times with each yogurt

４ Discussion(a) Lactic acid bacteria especially increased whenmixed with natto bacilli. The reason is that (a) canbe affected by the symbiotic action between thetwo kinds of lactic acid bacteria, (Bulgaria bacteria
and Thermophilus bacteria).
(b) has two kinds of lactic acid bacteria and increased
drastically, second to (a).
(c) has only one kind of lactic acid bacteria and nogreat increase.
From the above, having two kinds of lactic acid bacteria
seems to have a better relationship to natto bacilli.

５ Conclusion

・The combination Bulgaria bacteria and Thermophilus
bacteria works the best with natto bacilli.
・Two kinds of lactic acid bacteria increased more than
only one kind, when mixed with natto bacilli.

６ Future Study

To examine the percentage of increase of both Bulgaria
bacteria and Thermophilus bacteria

Sugar Content

Ethylene gas activates enzymes in fruits.

Hypothesis is:
The growth of plants is related to the light and more
ethylene gas is produced by hitting light.

The goal of my experiment
Check the amount of ethylene gas by hitting different
colors of light and to identified what color helps produces
more ethylene gas and makes fruits ripen sooner.

2 Experiment
Material：・5 cardboard boxes
・plastic bags
・LED lights ( , , , ) ・plastic bags
・AA batteries
・Sugar content meter・5 apples・5 kiwi fruits
Experimental Methods:
1.Set LED lights oneach cardboard
2.Measure sugar content
of kiwi fruits
3.Put an apple and a kiwi
in the same plastic bag
and seal.
4.Put the plastic bag into
the cardboard andturn on LED lights.

4.Consideration
The sugar content decreased when hit by pea green
light.
→ Probably because the hole to measure the sugar
content made the kiwi rot.
・Orange light increased ethylene the most・Blue and red light also increased ethylene morethan no light.
→A lot of ethylene gas was produced by the lightand the growth of the plant is related to the light.

6 Future Study
Some kiwi fruits rotted because of the holes madeto measure the sugar content.
→ Make holes smaller.
Some LED lights went out because of the longexperiment time.
→ Make the experiment time shorter.
I couldn’t get enough accurate data.
→ Repeat the experiments several times.
I didn’t check whether fruits other than kiwi fruit
have the same result.
→ Conduct experiments with other fruits.

5.Conclusion
Orange light is helpful in order to make fruits
sweeten more quickly.

Ant followed a line of ants’ Abdomens 5 times
Ant reacted to a line of ants’ Heads to some extent(traced it only once)
Never followed a line of ants’ Thoraxes or Ethanol
A line of ants’

4.Discussion
2.Procedure
1.Refrigerate 20 Japanese Wood Ant
2.Cut ants into 3 parts ; Head , Thorax and Abdomen
3.Put each part into 3 test tubes , and squash itafter adding 1ml Ethanol to each tube

The ant reacted to a line of ants’ Abdomens without
fail→ An ant’s Action Pheromone must be released fromits Abdomens
Why the ant also reacted to a line of ants’ Heads ?

5.Liquid of ant’s Abdomen

An ant’s Antenna has a lot of thick hairs
Ants detect Liquid Pheromones by touching them withthe hairs of their Antennae→ The Ant may have reacted to the Pheromones
attached to the surface of the Antennae
because I didn’t wash ants before I cut them

5.Next Task
I want to research how long the effect of Action

3.Results

Diffraction:
・is a phenomenon that waves turn behind slits.
・becomes outstanding when the slit-width is less than the wave
length. (Fig. 1)
Higher sounds have shorter wave length than lower sounds→when the slit-width is same, higher sounds are not likely todiffract.
→when many low sounds and few high sounds are diffracted, we
can make a change in sounds at the point where the high soundbegins to be heard. (Fig. 2)

peopleFig.1.difference of diffraction bywave length

PurposeA change in sounds enables blind people to stop 70cm (stride length)
before a crossroad.

Hypothesis
When the slit-width is less than the wave length of the high sound,many low sounds and few high sounds are diffracted. This makes achange in sounds and enables people to stop before a crossroad.

Preceding study（by Mr. Sakaguchi）
・measured the distance between a crossroad and the point that theblindfold subjects noticed the change in sounds.
・found that when the frequency of a sound is higher than 2000Hz,
the change was easy to be noticed and that the sound was hardly
affected by the noise at the crossroad.

This study
・used a smartphone application in order to get more accurate data.
・used sounds of 1174Hz and 220Hz, because they are comfortable.

Width of slit(cm)4.Discussion
・The sound of 1174Hz was hardly diffracted when the slitwidth was longer than 29cm, (the wave length of 1174Hz).
→we examined a slit-width of less than 29cm in order tomeasure the high sound before the crossroad.
・When the slit-width was 15cm, the distance that wemeasured was closest to stride length.
→15cm was the best slit-width

5.Conclusion
15cm is a little shorter than the wave length of the highsound, 29cm.
→Our hypothesis was proved right

Experiment 2. Confirm the existence of amino acid
• Both NaOH and KOH solution contains aminoacid is foundExperiment 3. Separate noxious elements• No sediments is produced
Experiment 4. experiment of dialyze• Amino acid exists inside, but not outside

I hope we can eat our hair
Hypothesis
Strong acid solution can dissolve hair, andamino acids, appear in this solution

４．Discussion• Hydroxide ion can cut peptide bonds• No precipitation action happened in experiment 3
because there were little noxious substance• Amino acid existed in semipermeable membrane
because peptide bonds weren’t cut perfectly,
amino acid didn’t pass semipermeable
membrane

２．Experiment

Experiment 1. Dissolve hair
• Soak hair in solution of strong acid or strong basefor a week
⚫ Use solutions which dissolve hair inexperiment 2, 3 and 4

Experiment 2. Confirm existence of amino acid• Check for amino acid with solution of ninhydrin
Experiment 3. Separate noxious elements such as
lead, mercury, cadmium① Add hydrogen sulfide to solution which
dissolves hair
② Add solution① to NaOHaq③ Filter produced sediment
Experiment 4. Experiment of dialysis① Make a device likethe one shown in the
picture, and leave it
for a week
② Check for existence ofamino acid both inside andoutside semipermeable
membrane.

５. Conclusion
Basic solutions can dissolve hair. Amino acid andprotein, whose bond isn’t cut perfectly, exist in thesolution which dissolved hair

６. Future Study• Research how much amino acid the solution
contains• Prove noxious substance isn’t included• Do experiments with many different types of hair
• Eliminate a horrible smell of the solution• Make it delicious

To Promote Paper Products Recycling
Results

Introduction⚫ In Kariya City, it is possible to get collected“Burnable trash”, “Plastic trash”, and “paper”.
⚫ But, we found the fact that it is less often to
see the trash bags for “paper” compared withthem for “Burnable trash” and “Plastic trash”.
Berecycled

Collect as “paper”

Paper
products

Collect as“burnable trash”

Be burnedup (Be notrecycled)

We want to recycle more
paper products !

Research （By Questionnaire）◆ About half people don’t know this trash bag.
◆ Advantages and right way to separate trashhaven’t been conveyed .
◆ Though almost 90% stores sell them, many
people don’t know well where they are sold.

Discussion
In order to get to know about trash bags
for paper, we have to tell the existence ofthem to all people living in Kariya.

Experiment
We circulated the leaflets (circular bulletin)
for two areas of Kariya City.
Leaflets urge people to use this trash bag
and to recycle.

①Do you know the trash bag for paper products?
Yes

47%

No
53%

Saw at houseor store② For people who answered “yes” in ①
Have you ever used them?
16%

Yes
No
84%

Many people don’t know its advantage,
how to use, and where they are sold.

Research（At Store）
Trash bags for paper products
were sold atseven of eight
storesnear Kariya High School.

Result
The amount of collected paper products
increased!
December ➡ 3boxes
January ➡ 4boxes

However… Internationalization is not seen important.
Foreign people can’t get useful information.

⚫

Japan is largely a single ethnic state different
from Australia.
⚫ There are a lot of big companies in Kariya city.
⚫ the number of workers from foreign countries
is increasing.
