TITLE:  The Taste Test

STUDENT RESEARCHER:  Kerri Sawicki
SCHOOL:  Dawson Elementary School
         Holden, Massachusetts
GRADE:  5
TEACHER:  Wayne Boisselle, M. Ed.


I.  STATEMENT OF PURPOSE AND HYPOTHESIS:

I wanted to find out if boys and girls could recognize the 
taste of foods without looking at the food or smelling it.  My 
hypothesis states that boys and girls will recognize the taste 
of foods equally.

II.  METHODOLOGY: 

First, I wrote my statement of purpose.  After that I wrote a 
literature review.  Then I developed my hypothesis.  Next, I 
performed my experiment.  I randomly chose three girls and 
three boys to help me with this experiment.  I took each 
student into the hallway and blindfolded him/her and had her 
hold his/her nose.  Next, I gave them each a sample of salt, 
coffee, lemon juice, and sugar with water in between to clear 
out their mouths.  After giving a sample of food, I asked if 
the subject could correctly identify if it tasted sweet, sour, 
salty, or bitter.  I recorded my results on a chart.  When my 
experiment was over I analyzed my data.  Then I accepted or 
rejected my hypothesis and drew conclusions.  Finally, I 
applied my research to the world.  

III.  ANALYSIS OF DATA:

One girl incorrectly answered on the sour test, 2 correctly 
answered on bitter, everyone correctly answered on the sweet, 
and everyone correctly answered on the salty.  One boy 
incorrectly answered on the sour test, 2 incorrectly answered 
on the bitter, 1 incorrectly answered on the sweet, and 
everyone correctly answered salty. 

IV.  SUMMARY AND CONCLUSION:

A lot more students incorrectly identified bitter more often 
than sour, salty, or sweet.  Fewer students incorrectly 
identified salty than anything else.  My data shows that girls 
can recognize the taste of foods better than boys.  Therefore, 
I reject my hypothesis which stated that girls and boys can 
recognize the taste of foods equally.  

V.  APPLICATION:

My project can be used in the world by telling people who like 
to cook that salty is the strongest taste and more people can 
recognize what it is and bitter is the weakest taste and fewer 
people can recognize what it is.  



TITLE:  Which Taste Sense Is More Sensitive?

STUDENT RESEARCHER:  Kimberly Convery
SCHOOL:  Dawson School 
         Holden, MA
GRADE:  5
TEACHER:  Wayne Boisselle


I.  STATEMENT OF PURPOSE AND HYPOTHESIS:

I wanted to find out which taste sense is the most sensitive: 
bitter, sweet, sour, or salty.  My hypothesis states that the 
sweet sense will be the most sensitive. 

II.  METHODOLOGY:

The first thing I did was write my statement of purpose.  Then 
I did my literature review.  After this, I used the information 
to develop my hypothesis.  Next, I began my experiment.  I 
tested everyone in my class.  I called them into the hallway 
one at a time and blindfolded them.  I then gave each student a 
small sample of sugar, salt, lemon juice, and coffee.  As I 
gave each student a sample to taste, she had to tell me when 
the taste was recognized.  I used a stopwatch to time this.  I 
repeated this with each sample and each students.  In between 
samples I gave students water to drink to get the taste out of 
their mouths.   I then analyzed my data and accepted or 
rejected my hypothesis.  Finally, I drew my conclusions and 
applied my data to the world outside of the classroom.
   
III.  ANALYSIS OF DATA:

My data shows that 98% of the people I tested thought that the 
salt sensation was more sensitive .  The two percent that was 
left thought the coffee or bitter sensation was more sensitive.

IV.  SUMMARY AND CONCLUSION:

A majority of people thought that the salty sensation was more 
sensitive than any of the other sensations.  Therefore, I 
reject my hypothesis that stated that the sweet sense will be 
more sensitive.  

V.  APPLICATION: 

My project can be used in the world by people because they will 
know the salty sensation is more sensitive, so they should use 
less salt in their food.



TITLE:  Which Plant Will Grow Best?

STUDENT RESEARCHER:  Lauren Schneider
SCHOOL:  Dawson Elementary School
               Holden MA.
GRADE: 5
TEACHER:  Wayne A. Boisselle


I.  STATEMENT OF PURPOSE AND HYPOTHESIS:

I would like to find out how long it takes for two plants to 
grow, one is in the dark and another one in light.  My 
hypothesis states that the plant that is in the light will grow 
best.

II.  METHODOLOGY:

First, I wrote my statement  of purpose.  Next, I did a 
literature review to find out information on my topic.  From my 
literature review I developed my hypothesis.  I then performed 
my experiment.  I put five marigold seeds each into two pots 
containing soil and water.  I placed one pot in my teacherÕs 
closet and the other in a sunny window.  I checked each plant 
each day and watered each plant when the top of the soil was 
dry.  I recorded my data on a collection chart.  When my 
experiment was over I analyzed my data and drew my conclusions.  
Then I accepted or rejected my hypothesis.  Finally, I applied 
my data to the real world.     
     
III.   ANALYSIS OF DATA:

My graph shows how tall each plant grew.  The plant in the dark 
reached 7.5 cm and then it died.  My other plant in the sun 
grew really well.  It kept on growing almost 2.5 cm every day.  
It reached a final height of 22.5 cm.  At the end of the 
experiment, my flower bloomed.  It was really pretty.

IV.   SUMMARY AND CONCLUSION: 

My data shows that the plant growing in the light grew best.  
Therefore, I accept my hypothesis which stated that the plant 
that is in the light will grow best.   

V.  APPLICATION:

My project can be applied to the world because I can tell 
people that if they have a plant in the dark, it will not grow 
well, but one in the light will.



TITLE:  Super Munchers

STUDENT RESEARCHER:  Katie Sobiech
SCHOOL:  Dawson School
         Holden, Massachusetts
GRADE:  5
TEACHER:  Wayne A. Boisselle



I.  STATEMENT OF PURPOSE AND HYPOTHESIS:

I would like to find out if girls can play the Super Muncher 
computer game better than boys.  My hypothesis states that the 
girls will get a higher score than boys. 

II.  METHODOLOGY:

First, I wrote my statement of purpose.  Then I wrote my 
literature review.  After that I developed my hypothesis.  
Next, I did my experiment.  I chose four students (two boys and 
two girls) who had never played the Super Munchers game before.  
I taught each student how to play and then let them play the 
same game for five minutes.  After each student had a chance to 
play once, I had them play a second time.  I wrote all my data 
in a collection chart. I then examined my data and wrote my 
analysis of data.  With that information, I accepted or 
rejected my hypothesis.  Finally, I drew a conclusion and 
applied my data to the real world. 

III.  ANALYSIS OF DATA:

John got 285 points in his first trial and 425 on his second 
trial.  Chris got 265 points on his first trial and 570 on his 
second trial.  Linnea got 235 points on her first trial and got 
500 on her second trial.  Kim got 300 points on her first trial 
and on her second trial she got 600.

IV. SUMMARY AND CONCLUSION:

In regards to total scores, the girls beat the boys by 90 
points. Therefore, I accept my hypothesis which stated that the 
girls will get a higher score.  

V. APPLICATION:        

This project can be used by teachers because it says that you 
should teach kids for a longer period of time before testing 
them.  All students scores on the second game played were much 
higher. 



TITLE:  What Grows Faster?

STUDENT RESEARCHERS:  Ian Duffy
SCHOOL:  Dawson Elementary School
         Holden, Massachusetts
GRADE:  5
TEACHER:  Wayne Boisselle


I.  STATEMENT OF PURPOSE AND HYPOTHESIS:

I wanted to study plant growth and see if liquid plant food 
makes plants grow faster.  I wanted to find out if a plant 
grows faster with water from the sink, distilled water, or 
liquid plant food.  My hypothesis stated that the plant watered 
with Miracle Grow will reach the seventeen cm mark first.

II.  METHODOLOGY:

First, I wrote my statement of purpose.  Then I went to the 
school library and found information for my literature review 
and wrote that.  Next, I developed my hypothesis and did my 
experiment to test it.  I used six bean plants in all.  All 
pots were filled with the same type of soil and one bean seed.  
Two pots were fed a solution of Miracle Grow and water, two 
were watered with tap water, and two were watered with 
distilled water.  I put all six plants in the same sunny window 
to keep the light and heat variable the same and I watered them 
with the same amount of liquid at the same time.   I measured 
my plants each day until one reached 17 cm.  After my 
experiment, I wrote my analysis of data and accepted or 
rejected my hypothesis.  Finally, I drew my conclusions and 
applied my research to the real world.

III. ANALYSIS OF DATA:

My research shows that the plant that was fed Miracle Grow grew 
the fastest.  The plant watered with Miracle Grow grew to a 
height of 18 cm.  The plant watered with distilled grew to a 
height of 17 cm.  The plant watered with tap water grew to a 
height of 15 cm at the end of my research.      

IV. SUMMARY AND CONCLUSION:

I found out that the plant watered with Miracle Grow grew the 
fastest.  I therefore, accept my hypothesis which stated that 
the plant watered with Miracle Grow would reach the seven inch 
mark first.  
 
V. APPLICATION:

My research findings will help people know that Miracle Grow is 
better than distilled water and tap water for growing plants.



TITLE:  Which Grows Faster, Carrots Or Beets?
 
STUDENT RESEARCHER:  Heather Marean
SCHOOL:  Dawson Elementary School
               Holden, MA
GRADE:  5
TEACHER:  Wayne A. Boisselle


I.  STATEMENT OF PURPOSE AND HYPOTHESIS:

I chose to do my project on plants because I wanted to see 
which grows faster, beets or carrots.  My first hypothesis 
stated that the beets will take 3 to 6 days to germinate and 
three weeks to start developing.  My second hypothesis stated 
that the carrots will take 1 to 2 1/2 weeks to germinate and 
four weeks to start developing.

II.  METHODOLOGY:  

First, I wrote my statement of purpose.  After doing a 
literature review, I wrote my hypothesis.  Next, I performed my 
experiment.  I planted ten carrot seed and ten beet seeds in 
pot filled with potting soil.  I watered them both the same and 
kept them in the same sunny window.  I observed my plants each 
day and recorded all this information on a chart.  Then I 
looked at and analyzed my data.  I then accepted or rejected my 
hypothesis.  Finally, I drew my conclusions and applied my data 
to the real world.

III.  ANALYSIS OF DATA:

When the carrots grew they were a yellowish-green in color.  
When the beets grew the stems were fuzzier and the leaves were 
a jungle-green color.  On day seven, the carrots germinated.  
On day three, the beets started to germinate.  On day nine, the 
carrots were 1.5 cm tall and the beets were 5 cm tall.

IV.  SUMMARY AND CONCLUSION:

My data shows that the beets started to germinate 4 days faster 
than the carrots.  Also, the carrots grew much slower and were 
much shorter than the beets.   Because of my data, I accepted 
both of my hypotheses which stated that the beets will take 3-6 
days to germinate and the carrots will take 1 to 2 1/2 weeks to 
germinate.   

V.  APPLICATION: 

My project can be used in the real world for people who plant 
gardens.  This project will inform them that they should plant 
their carrots before their beets because the beets germinate 
faster than the carrots.



TITLE:  Color-Blindness 

STUDENT RESEARCHER:  Aimee Blaquiere
SCHOOL:  Dawson Elementary School
         Holden, MA
GRADE:  5
TEACHER:  Wayne A. Boisselle


I.  STATEMENT OF PURPOSE AND HYPOTHESIS:

I want to know if fifth graders are color-blind just like my 
brother and how color-blindness affects people.  My first 
hypothesis states that girls will correctly identify all the 
shapes on a color-blindness chart.  My second hypothesis states 
that at least one boy will incorrectly identify at least one 
shape on a chart.

II.  METHODOLOGY:

First, I wrote my statement of purpose.  Next, I reviewed the 
literature and then developed my hypothesis.  Then I performed 
my experiment.  I used three color-blindness charts that I got 
from my eye doctor.  Each chart tested different colors.  I had 
each student in turn (five girls and four boys) look at each 
chart and tell me what she/he saw.  I recorded my data and then  
analyzed it.  Next, I accepted or rejected my hypothesis.  
Finally, I drew my conclusions and applied my data to the 
world.  

III.  ANALYSIS OF DATA:

Overall, four out of five girls identified all the shapes on 
the charts correctly.  One girl got one shape wrong on charts 2 
and 3.  Three out of four boys identified all the shapes on the 
charts correctly.  One boy got one shape wrong on chart 3.

IV.  SUMMARY AND CONCLUSION:

All my subjects correctly identified the shapes on chart 1.  
One girl got one shape wrong on chart 2.  One girl and one boy 
got one shape wrong on chart 3.  Therefore, I reject  my first 
hypothesis which stated that the girls will correctly identify 
all the shapes on a color-blindness chart.  I accept the 
hypothesis that stated that at least one boy will incorrectly 
identify at least one shape on a chart.

V.  APPLICATION:

Towns, cities, or villages can use this information to find out 
if they have a lot of people in their area that are color-
blind.  If there are,  they should make labels for important, 
colorful signs.  For example, on a stoplight they could label 
the green light Go and the red light Stop.



TITLE:  Freeze It!  Freeze It!  Hurry!  Hurry!

STUDENT RESEARCHER:  Thomas Alleman
SCHOOL:  Mandeville Middle School   
         Mandeville, Louisiana
TEACHER:  Mrs. M. Smith
GRADE:  6


I.  PROBLEM AND HYPOTHESIS:
      
I wanted to find out if different kinds of liquids freeze in 
the same amount of time.  My hypothesis stated that the water 
will freeze first.

II.  METHODOLOGY:
     
I stated my purpose, conducted my review of literature, and 
developed my hypothesis.  Then I measured out 60 ml. of each of 
the following liquids and put them into plastic cups: water, 
milk, orange juice, and Gatorade.  Then I placed all four cups 
into the freezer, set on the coldest temperature, and timed how 
long it took to freeze them.  I checked them every 10 minutes 
with a toothpick.  Then I recorded my results and repeated my 
test two more times.  Finally, I analyzed my data, wrote my 
conclusions, and accepted or rejected my hypothesis.

III.  ANALYSIS OF DATA:
     
The water froze in an average of 75 minutes.  The orange juice 
froze in an average of 103 minutes.  The milk froze in an 
average of 92 minutes.  The Gatorade froze in an average of 84 
minutes.

IV.  SUMMARY AND CONCLUSIONS:
    
I discovered that the water did freeze the fastest.  Therefore, 
I accept my hypothesis which states that water will freeze the 
fastest.

V.  APPLICATION:
     
During baseball season, I like to freeze something to drink 
before a game.  I now know that water will freeze the fastest.



TITLE:  Earthworms and the Germination and Growth of Seeds

STUDENT RESEARCH:  Kimberly Vaughn
SCHOOL:  Mandeville Middle School
         Mandeville, Louisiana
GRADE:  6
TEACHER:  Mrs. Smith


I.  STATEMENT OF PURPOSE AND HYPOTHESIS:  

I wanted to find out if earthworms affect the germination and 
growth of lima bean seeds.  My first hypothesis states that 
more seeds will germinate in the pot with the earthworms.  My 
second hypothesis states that the lima bean plants will grow 
taller and faster in the pot with the earthworms.

II.  METHODOLOGY:

First, I soaked the lima bean seeds in regular tap water for 24 
hours.  I then planted six seeds each in two identical pots 
which contained eight cups of potting soil.  Each pot was 
watered with one cup of regular tap water each week on the same 
day of the week.  Six earthworms were placed into pot B, while 
pot A, the control pot, remained without earthworms.  Both pots 
were placed on a window sill to receive sunlight.

III.  ANALYSIS OF DATA:

The results showed that in pot A, the control pot, five of six 
seeds germinated and grew with the tallest plant reaching 30 
inches.  In pot B, the pot with the earthworms, six of six 
seeds germinated with the tallest plant exceeding 36 inches.  
The seeds in pot B also germinated 1-2 days sooner than the 
seeds in pot A.

IV.  SUMMARY AND CONCLUSION:

My data confirmed that the germination and growth of lima bean 
seeds is affected by the presence of earthworms in the soil.  
The number of seeds that germinate and the height of the plants 
that grew exceeded that of the seeds and plants without the 
earthworms.  I accepted both of my hypotheses.

V.  APPLICATION:

I can apply this information in the real world by using 
earthworms to help germinate seeds in my own garden.  This will 
enable me to save money on fertilizer and to save the 
environment from excessive use of chemicals.
