and blowing the gums all on
the same day. These proce-
dures all helped me really
much to make a fair ex-
periment and also to keep
track of the bubble gums. I
think that the feedback that
Hayen Kim gave to me
helped my experiment a bit
because she gave me an
idea of lung capacity and
also how can I measure the
amount of air that people
are blowing in. These prob-
lems
were
im-
mediately
solved
when I
changed
my sample
My hypothesis was that
Hubba Bubba is capable of
blowing the largest bubble.
My procedure was to about
10 different types of bubble/
chewing gum and try to
blow the bubble with every
one of them. My variables
are the country that the
gum is manufactured in
because I think that rich
countries will produce better
gum. Also, whether the gum
is bubble gum or not be-
cause I want to see if it
matters or not. Last but not
least, the quality of the gum
because I want to see what
makes the quality of the
gum good or bad. My sam-
ple size is 10 different types
of bubble/chewing gum and
one person (me) trying to
blow them. The reason I
chose 10 different types of
bubble gums was because I
wanted to experiment gums
that we could see in our
daily life thus types of gums
that are popular among
people. The reason that I
chose to only let one person
(me) to blow the bubble was
because I had to keep track
of air and amount of minute
that I chewed. If other peo-
ple blew the gum, I can’t
measure the amount of air
that they are blowing the
bubble with thus I also
can’t keep track of how
good or bad a person is in
blowing bubble gums. My
hypothesis was supported
by my data because Hubba
Bubba is capable of blowing
the largest bubble. Three
things that I did to keep my
experiment fair was to chew
the gum for a minute before
blowing the bubble, using
the gum with same sizes,
size to only one person doing
the whole experiment. In my
opinion, I think that giving
feedbacks to each other issuch an awesome idea be-
cause you can share your
ideas around the world. Fol-
low Up Questions:
1. Will the conclusion change
if I used more varieties of
people for my experiment?
2. Does blowing a larger gum
than others mean that you
have larger lung capacity
than others?
3. What are some main differences between the chewing gum
and the bubble gum?

Hypothesis: I think
GOO.N will hold the
most water.
Procedure: First, I'll
use 4 types of diaper
brands. The 4 diaper
brands I used were:
GOO.N, Huggies,
Pampers, and Drypers.
Then I'll insert the
equal amount of water
on each diaper at the
same time. After I fin-
ished pouring all the
water, I’ll see which
diaper held the great-
est amount of water.
Variables: Same
amount of water in-
serted for each diaper.
Because if we do all
different amount of
water, it wouldn’t be
fair a fair experiment.
Sample Size: 4 brands
of diaper. Same
amount of water for
each diaper. Because
4 brands is a fair
amount and less than
4 isn’t fair.
Conclusions: My hy-
pothesis wasn't sup-
ported by the data. I
thought GOO.N
would hold the most
water but it was actu-
ally Pampers. The 2nd
was GOO.N. 3rd was
Huggies. The diaper
that couldn't hold the
most water was Dry-
pers. I knew if they
hold the most water
by feeling the diaper,
if it was dry or wet,
and if it was heavy or
not.
Sources of Error: I
tried three ways to
make this a fair ex-
periment. I accom-
plished the experi-
ment in the same en-
vironment. I used
equal amount of water
to pour in each diaper.
I used the same size
of diaper: L.
Use of Feedback: The
person who gave me
feedback was Tanya.
She just said that I
should just have to
pour in the water
slowly. If I put all
the water in the same
time, the diaper
might not take all the
water easily and
burst. I just took that
advice and used that
way. It helped a lit-
tle.
Follow up Ques-
tions:
1. Would the results
change if I pro-
ceeded my experi-
ment somewhere
cold?
2. If the diapers were
all different sizes
(they’re sizes like
XL, L, etc. in diapers
too) would the
amount of water they
could hold change?
3. If it was already a
worn diaper but not
wet, would the re-
sults change?

Hypothesis: I think the
ice will melt in water
faster. Because water
can absorbed ice faster
while air can absorbed
ice but it takes time for
it to melt.
Sample Size: I used 2
ice cubes. Because one
is to put in the water
and one is to put it on
the table. I used 2 be-
cause I thought it will
be a lot easier than get-
ting 6 ice cubes and
experimenting them.
Because then I will be
confused, and I’ll have
to do the experiment
again.
Variables: I used 2 icecubes and put one of
them in the water and
one of them on the ta-
ble. Because then it will
be a lot easier to see
both of them and timing
it.
Procedure: I will use 2
ice cubes and put one on
the table and one in thewater. I will put 2 of
them besides each
other so it will be eas-
ier to time both of
them and it will not be
confusing because, if I
experiment 6 ice cubes,
it will take time and
hard for me to check
if the ice cubes are
melting or not, and
the timing will be
wrong.
Conclusions: My Hy-
pothesis was sup-
ported by the data. I
thought that the ice
cube will melt faster
in the water than the
air. Then after ex-
perimenting it, it was
the ice in the water
that melts faster.
Source of Error: I
think I should use
the same sized ice
cube. Because the
one that is on the
table seems a littlebigger than the one
in the water. And I
think I should use a
transparent glass so
I could see the melt-
ing ice better and
timed it better.
Use Of Feedback:
The feedback, from
Wendy Byeon, helpedme because I really
need more specific
information in my
hypothesis for exam-
ple, ‘I think the ice in
the water will melt
faster’ is not spe-
cific, ‘I think the ice
in the water will melt
faster because water
can absorb ice quickly,
while air can absorbed
ice but it takes time
to melt it faster’ that
is a specific hypothe-
sis because I explain
why I think this is
faster and this is not.
Question: Will ice cube melt faster with air or water? By: Amira

1.If I put the ice in cold water,
will the ice melt slower than
the one that is on the table?2.
if I put a bigger ice in the wa-
ter and a smaller ice on the
table, will the ice in the water
still be faster?

spoons of salt tofloat an egg. Source of error: First of all, I startedwith the sameamount, and sametemperature of thewater. Secondly, Imeasured theamount of salt per-fectly. Lastly, I usedthe same type of salt(I used a salt that’sreally salty, becauseI thought the weakones couldn’t makethe egg float).Feedback: The
feedback was: Dear Jun Woo,I think that you can add more details in your hypothesis. I
think that different kinds of eggs will have a different amount of salt to float the egg be- cause it can have different weights and the amount of yolk and egg white inside the egg might be different.Feedback from
Denny helped mevery much. It mademe think of a mis-take I made; I usedthe same type ofegg, but I didn’tmeasure if it wasproduced in thesame day, and theegg’s parents; differ-
Hypothesis: I think theegg will float when I put 9spoons of salt.Procedure: First of all, Iwill prepare one cup withnormal water. Next, I willput small amount of saltin the cup and check ifthe egg floated or not. Ifnot, I'll put a little more, and more until the egg floats(When I'm putting the salt in, I will measure by tea-spoons) .Variables: 3 cups of salt ( I think that's enough). Nor-mal tab water.Sample Size: Twice each time (I put the salt in)Question: How muchsalt does it take to floatan egg?Hypothesis: two tablespoons.
Procedure: First of all, Iwill prepare one cup withnormal tab water. Next,I'll start with 6 tablespoon. Then I'll check if the egg floated or not. Afterthat, I'll put 8 table spoon, then add 2 more table spoon(on and on until the egg floats).Variables: 1 1/2 cup of normal tap water. One egg (notboiled) [I put this amount of water, because I thought itwas just enough for this experiment – I thought toomuch water would take a large amount of salt].Sample Size: 2 tablespoons of salt every timeI put it [I thought puttingone table spoon wouldn’treally make the egg float,so I decided to put 2 ta-ble spoons every time Iput them].
Conclusion: My hy-pothesis was not supported by my data, I thought itwould be enough to float an egg by putting 9 spoons ofsalt in table spoon, but I was wrong. I needed 13 table
ent type of chickens.
Follow up ques-tion:
-Does the tempera-ture of the water ef-fects an egg float-ing?-Will different typesof salt change theresult?-Will the type of cupor a container thatcontains the watereffect the result?

Conclusion:
My question is “If I playcomputer or PSP games
while playing chess with
my dad, will it affect my
win or loses? Which one
will affect me more?”
My hypothesis was that I
think that the game in
computer will affect me
more because I need to
focus more and my hy-
pothesis was supported
by my data because I lost
the most while playingcomputer game (The
computer game name is
Cross Fire [VN]).
Source of error:
I didn't actually think when I was playing cross
fire in the computer
while playing chess with
my dad, I just moved
randomly so I think that
it's not that fair. Next
time I can think before
making a move in chess.
Another mistake is that
when I played the other
games, I think I focus too
much on them instead of
focusing on the chessgame. And my dad kept
texting so maybe he
weren’t focusing on the
chess game too.
3) Win
After that I tried to play
chess with me dad while
playing PSP:
1) Win
2) Lose
3) Lose
1st three games with all
my focus.1) Win
2) Win
3) Lose
Now the chess games that
I played while playing
Cross Fire.
1) Lose
2) Lose

D A T A C H A R T . . .
your question, its good
question but its hard to
experiment the chess in
PSP and Computer be-
cause some people might
like using computer or
PSP to play chess andthey might like it so its
hard but I still like it and
I also have PSP and
maybe I can try your
experiment.”
Follow up questions:1. Will my data change if
I play a different game in
the computer while play-
ing chess with my dad?
2. Will the volume of the
game's sound affect mydata?
3. Will my data change if
the surrounding is
changed?
Use of feedback: The feedback helped me
at nothing, because the
guy just said that this is a
cool experiment and
nothing more. By the
way I think he miss un-derstood my experiment.
He said:
“Hey Edwin!!!!!I’m
Kevin but I will be use
K.J. for this account be-
cause there is 2 Kevin in
our grade. So after I read

ing chess with my dad.
Always try your
best! Then God
will do the
rest!!!!!
