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?

WHICH D IAPER HO LDS THE MOS T

WATER ? BY: HY E RIN



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 because 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!!!!!
