Conclusion: My hypothesis

was that I thought that for

children 11-13 they would be

mostly be attracted to kinder

and better-looking people. I

was right with those factors.

However, with my survey I

found many other additionalanswers. For example, 16 out

of 25 people said that they

judge personality over ap-

pearance. Just about all of the

25 students I surveyed said

that they like nice, caring,

honest, gentle people. Due to

that, I think most teenagers

might actually be looking for

exceedingly caring people

that can maybe be rough at

times, yet still are genuinely

nice.Sources of error: My range

for the age of students I

would survey was 11-13

years old. Also, when I did

my survey I asked the same 3

questions to every student,

with the questions it gave

them free choices of any

answer they wanted. When I

did my survey I didn’t write

down the names of the stu-

dents, instead I gave them

numbers so nobody could

know who they were, and so

they would feel more open

in writing things that may

even embarrass them.

Use of feedback: Mr. J's

feedback was pretty useful.

He told me to reduce my

sample size because 50 peo-

ple might have been too

much work. I reduced my

sample size as I agreed that I

Hypothesis: I think that for

children 11-13 they will be

mostly attracted to kinder and

better-looking people. For

kids aged 14-15 I think they

will be attracted by looks,

and the out-going or sensitive

personalities of other people.Whatever relates to them

most.

Procedure: I will create a

survey on different personali-

ties and looks. In the survey,

I will ask them whether they

prefer appearance over per-

sonality, what factors of per-

sonalities attract them, and

also give them an optional

question of extra factors that

may attract them to a person.

With the survey I will seewhat matters to most people

about liking someone, and

what factors most trigger

people’s attraction.

Variable: The different fea-

tures of people that I will

include in my survey. The

features about people that

students chose were kind of

random because I gave them

the free choice of choosing

any sort of characteristics

about people that attract

them.

Sample size: I chose 25 stu-

dents. I chose this number of

students because I wanted to

get a good idea on most

popular preferences. With

choosing a rather large sam-

ple size I was also planning

on making it a more accurate

experiment with a greater

range.

wouldn’t have enough time to survey

so many people. In addition, I lowered

my age group range to keep my ex-

periment more organized.

Follow up questions: 1) What attracts 11-13 year olds? Do

the answers vary if they are from dif-ferent schools?

2) Do adults and children have similar

preferences in people?

3) Do different races have different

ideals about people that attract

them?

What features of a person attract another person for

ages 11-13?

Hypothesis: I think

the Kellogg’s ce-

real has the mostraisons

Procedure: So I

would buy a lot of

cereal from differ-

ent brands in Viet-

nam.

Variable: 5 differ-

ent kinds of cereal.

Sample size: 5 dif-

ferent kinds of

brand

Conclusion: I think

my hypothesis was

right. I got like 3 or

4 cereal and

counted the raisin

but I think K Ce-

real has the mostraisins.

Source of Error: I

did the one with no

raisins....

Use of Feedback: I

got the feedback

good I used the

feedback well.

Peer Feedback: I

think I used my

peer feedback care-

fully and well. For

example when Mr.

Johnston gave me a

peer feedback like

the title should be

better I would only

change the title anddon’t check others

and say that I’m

done. But another

thing is he said I

did very well so I

checked my work

over and over

again and I found a

mistake so I

changed it. If he

said a specific mis-

take I would only

change that but be-

cause of his peer

feedback he saved

my life.

Sources of Error:

When there is thiscereal brand for ex-

ample a Korean

brand called Tiger I

think, In the shop

there are many

boxes of Tiger in

the shop, but I only

bought one and

counted the raisin,

maybe in my box

there were 10 or 20

raisins but in the

other box maybe

there were 40 or

30, who knows? So

I think I need to

like change that. I

just counted the

raisins in the boxreally fast, so like I

thought I had to re

checked but I did

but I didn’t do that

well.

Sample Size and

Variables: I chose 5

because if it is ade-

quate it will be

like confusing be-

cause there are too

much cereal boxes.

If there are too

much like a same

brand but different

amount of raisins.

So like I think 5

amount of cerealbox is enough for

this experiment. I

even asked other

people how many

cereal boxes I

should do and they

said about 5 or 10.

Follow Up Ques-

tion: 1. Where

can we get the ce-

real that is a lot?

2. How should I

make my ques-

tion better?

“How Many Raisins are in Cereal?” -Ho Sung



Hypothesis: I think

people who are lefthanded kick with their

left leg with more con-

trol and accurate andright handed kick with

their right leg better

because people whoare right handed usu-

ally kick with their

right leg better andvice versa.

Procedure: I will use a

soccer ball (the samefor each person) and

take 2 left handed

boys, 2 left handedgirls, 2 right handed

boys and 2 right

handed girls. In a tinyand tight place, the

person would kick the

ball 5 meters apart

where the cone will be

placed with each legand I would measure

the distance as preciseas possible and see

which leg kicks the

farther one.

Variable: boys and

girls in 7th grade that

have equal strength.Sample Size: 2 left

handed boys, 2 lefthanded girls, 2 righthanded girls, 2 right

handed boys. There

are not many lefthanded boys and girls

in ours school. So, I

limited my sample

size.

Feedback: I think Lu-

cas’ feedback did help

because he said thatmy hypothesis needs

to be more detailed

and why I think Ichose that hypothesis.

Conclusion: My hy-pothesis is supported

by my data because

right handed people

kicked the ball fartherwith their right leg,

left handed people

kicked the ball fartherwith their left leg.

Source of Error: Bytrying to make my ex-

periment fair, I tried to

mark the distance as

accurate as possible

because if I make anerror in marking the

distances, there mightbe a mistake in where

the distances the per-

son kicks the ball. I

used the same ball. If Iused a different ball,

there might be more

air in the other ball orless air in it and peo-

ple might be very un-comfortable with an-other ball and I use

people with the same

ball strength and con-trol, mostly people

from the soccer team

or people who can

kick with the same

strength.

Follow Up Questions:

1. If the distance was

longer, would it affect

how the person con-

trols the ball?

2. If I blindfold them,

would it be more ac-

curate or worst?

Which leg has the best control? - Rachie



Feedback:THIS IS THE REAL FEEDBACK

Dear Victor Khuong,

This is a very interesting experiment. Although the time that your checking,what I think, needs to be approximately the same. Maybe check the food eachday at the same time you left them. That way you might get a more accurate

result at the end. Also, what type of insects? Usually ants are the ones who goto the food that are left. Overall I think it's good.

THIS IS THE EVALUATION

When I have read the suggestions Michael Hall gave me, I thought thiswas very helpful. When he said about checking the food each day at theSAME time I left it and that it would be more accurate, I thought about it

and found out that maybe this suggestion was really helpful. But I didn’twant to be too specific about the type of insect, because maybe there

would be no ants, but lots of flies. Plus, I might not know what ate or

obtain the food.

Sources of Error:I try making this a fair experiment by keeping all the food in one place,

because if I had some of the food in one place, and the other food inanother place, some food might have less or more results than others and

they wouldn’t be so accurate. I also had checked the food at the sametime I have left the food so it would be more accurate. It was also a useful suggestionfrom Michael Hall. I also wanted to put it in/on somewhere so ALL insects are able toobtain it (on a picnic table outside). I know ants can climb, and flies can fly.

Sample Size and Variables:

Variables

I wanted to keep all the food items at the same place, (see sources of error) that will also

make all the food items at the same climate, because (for example), If I had 2 pieces of meat (exactly the same) one really hot and one not really hot, like frozen, there could bemore ants that like the hot meat more than the cold meat.

Sample SizeI chose to get 2 food items from each food group (including junk food) so I can getmore accurate results. Because (for example) some insects might like steak more thantofu in the meat group. Plus, if they like eating something in the dairy group, doesn’t

mean it likes ALL of the dairy products.

ContentConclusions:

My experiment has been accidently dispose of, so I have only gathered half of my data.Just to mention. (Should mark points off)

My hypothesis wasn’t really supported by the data because I thought thatgrain and dairy food items would be the most eaten, but the grain hasn’t been touched

since it was placed and the dairy has only been eaten a little. I guess my predictionsaren’t so correct. The best results were from the fruits and vegetables and the other junk food category. It turns out that the healthiest and unhealthiest food groups have the bestresults in my data collecting. So you should be more aware of insects trying to take the

fruit and vegetables, plus, your sweets.

Follow Up Questions:-What would of happen if it WASN’T thrown out?

-Would the insects rather like the one food item than the other (that are in thesame food group)?

-Does the portion of food matter to the insects?

What type of food do insects like the most?

By Victor

Photo of Experiment:All the food was each placed in a

cup.



Hypothesis: I

think that the

roses, honey, and

flowers will do

good and the dog

food, garlic, on-

ion, and trash will

do badly.

Procedure: take

one of the samples

and have the peo-

ple smell them.

Variable:

Sample size: One

piece for one per-

son because the

sample might get

infected by other

smells and that is

the reason why I

did that.

Source of Error:

Other smells

could have got on

the samples, and

so that if I squeeze

the sample it will

not change it any

more than the air

changes it. Maybe

the like of smell is

the same because I

did my family and

not people out of

my family so they

might messed up.

I think I should

have done kids

my age because

we like the same

things and havetested older peo-

ple so that the

verities would be

wider

Use of Feedback:

Did not get any

feedback.

Conclusions:

Follow up Ques-

tion:

1.Do there like of

smells or dislike of

smells change

over time?2.What causes the

trigger in the brain

to like smells or to

not like them?

3. Why do some

people like some

smells?

What type of smells do people like? By Kyle

Items that can be smelled

This is the chart that has the results of the experiment

This is a picture of my mom smell-

ing a piece of crunched garlic.

To me the results

Of the chat weredifferent of that

what I thought .Forthe garlic 2 peopleliked it. For the

onion on one liked itand 3 people liked itsome times and thatmade me think.

Rose that did notsurprise me at alland I thought that .Dog food 1 person

liked it that mademe think why do

they like it? Trashno one liked it and
