TITLE:  The Effect of Electromagnetic Fields on Plant Growth

STUDENT RESEARCHER:  Richard Kaufmann
SCHOOL:  Mandeville Middle School
         Mandeville, Louisiana
GRADE:  6
TEACHER:  Ellen Marino, M.Ed.


I.  STATEMENT OF PURPOSE AND HYPOTHESIS:

I wanted to know more about the effect of electromagnetic 
fields (EMF's) on plant growth.  The abbreviation EMF stands 
for electromagnetic fields.   They are produced when 
electricity flows through a wire.  The fields are silent and 
invisible.  Humans are not biologically equipped to detect 
them.  They go unnoticed even though we're surrounded by EMF's 
all the time.  You can be exposed to EMF's anywhere electricity 
flows such as through power lines, microwave ovens, electric 
ranges, electric razors, hair dryers, television sets, 
computers, air conditioners, and electric clocks.  I chose this 
because there is a great deal of controversy about whether 
these fields are dangerous to living organisms.  My hypothesis 
states that electromagnetic fields will have an effect on plant 
growth.

II.  METHODOLOGY:

First, I wrote my statement of purpose, review of literature 
about EMF's possible effect on plant growth, and hypothesis. 
Second, I gathered my materials: electric radio/clock, radish 
seeds, potting soil, and two identical pots.  Then I planted 30 
radish seeds in each of two pots.  The seeds were planted to a 
depth of one millimeter in the potting soil.  I placed both 
pots in front of a large, sunny picture window. Both pots 
received the same amount of sunlight and water each day.  The 
pots were one meter apart.

I placed the experimental pot on an electric clock/radio and 
left it there all through my research.  It received a 200 
milligauss electromagnetic field coming from the electric 
clock/radio.  The control pot received normal background EMF 
radiation of less than .5 milligauss.  The electromagnetic 
fields surrounding each plant were measured each day with a 
Gauss meter obtained from Central Louisiana Electric Company.

My methodology included several variables which I held 
constant: type of seeds, sunlight, amount of water, size of 
pots, kind and amount of soil, depth seeds were planted, and 
growing temperature.  The manipulated variable was the 
electromagnetic field applied to experimental plant.  The 
responding variables included the growth of the plants, the 
number of leaves on each plant, the color of the leaves, and 
the health of the plants.

I collected the following data and recorded it on a data 
collection sheet:  date of seed germination, average height of 
plants, average number of leaves per plant, color of plants and 
general health of plants.  I recorded the data for 14 on each 
of the two trials.  Then I accepted or rejected my hypothesis, 
wrote my summary and conclusion, where I accepted or rejected 
my hypothesis, and applied my findings to the world outside the 
classroom.  Finally I published my research in a printed 
electronic journal of student research.

III.  ANALYSIS OF DATA:

In trial one, all seeds had germinated in the experimental and 
control pots after four days.  On the fourth day, both the 
control and experimental group of plants grew an average of one 
and a half centimeters tall.  On the fifth day, both groups of 
plants grew to an average two and a half centimeters tall.  On 
the sixth day, the control plants were an average four 
centimeters tall and the experimental plants were three and a 
half centimeters tall.  On the seventh day, the control plants 
were six and a half centimeters tall and the experimental 
plants were six centimeters tall.  On the eighth day, the 
control plants were seven centimeters tall and the experimental 
plants were six and a half centimeters tall.  On the ninth day, 
the control plants were an average of eight centimeters tall 
and the experimental plants were an average of seven and a half 
centimeters tall.  On the tenth day of the experiment, the 
control plants were eight and a half centimeters tall and the 
experimental plants were eight centimeters tall.  The plants 
stopped growing on the eleventh day.  All plants in the control 
and experimental pots had two leaves by the end of the ninth 
day of the experiment.  All plants had two leaves by the end of 
the 14th day of the experiment.  The color of all plants in the 
control and experimental pots was green and their health was 
good.

In trial two, all seeds had germinated in the experimental and 
control pots after four days.  On the fourth day, the control 
plants grew to an average of two centimeters tall and 
experimental group of plants grew an average of three 
centimeters tall.  On the fifth day, the control plants grew to 
an average three centimeters tall and the experimental plants 
grew to an average of four centimeters tall.  On the sixth day, 
the control plants were an average five centimeters tall and 
the experimental plants were six centimeters tall.  On the 
seventh day, the control plants were six centimeters tall and 
the experimental plants were six and a half centimeters tall.  
On the eighth day, the control plants were seven centimeters 
tall and the experimental plants were six and a half 
centimeters tall. On the ninth day, the control plants were an 
average of seven centimeters tall and the experimental plants 
were an average of seven and a half centimeters tall.  On the 
tenth day of the experiment, the control plants were seven 
centimeters tall and the experimental plants were eight 
centimeters tall.  The plants in both pots stopped growing on 
the tenth day.  All plants in the control and experimental pots 
had two leaves by the end of the ninth day of the experiment.  
All plants had two leaves by the end of the 14th day of the 
experiment.  All plants were green and were in good health 
through out the second trial.

IV.  SUMMARY AND CONCLUSION:

The only difference between the two trials was that in the 
first trial the control plants which did not receive the strong 
electromagnetic field grew to an average height of nine 
centimeters while the experimental plants growing in the strong 
electromagnetic filed grew to an average height of eight 
centimeters.  In the second trial, the control plants grew to 
an average of seven centimeters and the experimental plants 
grew to an average of eight centimeters.

I averaged my data for both trials.  The control and 
experimental plants both grew to an average height of eight 
centimeters tall.  The plants in the control and experimental 
pots all germinated at about the same time in the first and 
second trial.  All the plants had two leaves, were green in 
color, and in good health by the end of the experiment.  I 
therefore reject my hypothesis which stated that 
electromagnetic fields will have an effect on plant growth.  On 
average, there was no difference between the growth in the 
control and experimental plants.

V.  APPLICATION:

I can tell gardeners that EMF's do not seem to effect plant 
growth.  The findings in this research should not be 
generalized to animal and human growth or health. Therefore, 
while EMF's may not affect plants growing in a garden, they 
still may affect the gardener.




TITLE:  Creating Fingerprints

STUDENT RESEARCHER:  Sean  Wilkinson
SCHOOL:  Arnn Elementary  School
         Sagamihara, Japan
GRADE:  3
TEACHERS:  Ms. Blanchard and Ms. Nett


I.   STATEMENT OF PURPOSE

I wanted to find out if black sand and tape could be used to 
make finger prints.  My hypothesis stated that tape and black 
sand could be used to make fingerprints.

II.   METHODOLOGY

I used black ink, sand, a plate, and clear tape for my 
experiment.  First, I made some black sand by mixing black ink 
with the sand.   Next, I put the black sand in the plate.  Then 
I put my  finger in the sand.  Finally, I lifted my finger and 
placed it on a piece of clear tape to make the fingerprints.

III.  ANALYSIS OF DATA

All of the finger prints that I tried to make with black sand 
and tape came out very clear.   I did not need a magnifying 
glass to see the fingerprints.

IV.  SUMMARY AND CONCLUSION

I accepted my hypothesis which stated that black sand and tape 
could be used to make a good fingerprint.

V.  APPLICATION

Police can use tape and black sand to make fingerprints when 
they don't have ink or a fingerprint expert available.



SOCIAL STUDIES SECTION



TITLE:  Student  Knowledge  of  World  Hunger

STUDENT RESEARCHER:   Gregory Horn
SCHOOL:  Mandeville Middle School
         Mandeville, Louisiana
GRADE:  6
TEACHER:  John I. Swang, Ph.D.


I.  STATEMENT OF PURPOSE AND HYPOTHESIS:

I  would  like  to  find  out  what  students  know  about  
world  hunger.  My  hypothesis  states  that  a  majority  of  
students  will  correctly  answer  75%  of  the  questions  on  
my  questionnaire  about  world  hunger.

I.  METHODOLOGY:

First, I  wrote  my  statement  of  purpose.  Then  I  reviewed  
the  literature on  world  hunger.  Next,  I  developed  my  
hypothesis  and  a  methodology  to  test  it.  Next,  I  
developed  a  questionnaire.  Then  I  drew  a  random  sample  
of  twelve  sixth  graders  to  which  I  passed  the  
questionnaires  out.  When  they  were  returned  to  me  I  
scored  them  and  recorded  the  results  on  a  chart.   Then  
I  analyzed  my  data.  Later,  I  wrote  my  summary  and  
conclusion.  Then  I  applied  my  findings  to  the  world.  
Finally,  I  published  an  abstract  of  my  research  
project.  

III.  ANALYSIS OF DATA:

I  sent  out  twelve  questionnaires  and  eleven  were  
returned.   The  majority  of  students  did  not  know  that  
drought,  flooding,  plant  diseases,  and  war  were  the  
four  leading  causes  of  famine.  All  the  students  knew  
that  over  one  million  people  died  from  hunger  and  
diseases  caused  by  famine  in  1984.  A  majority  of  
students  did  not  know  that  more  deaths  have  occurred  
because  of  famine  than  from  every  war  ever  fought  in  
the  world.  A  majority  of  7  students  agree  that  famine  
is  the  very  worst  of  all  disasters.  A  majority  of  
students  knew  that  China,  India,  and  Russia  had  
suffered  the  most  from  famines.  A  majority  of  seven  
students  knew  that  a  drought  in  China  during  the  years  
1816-1819  killed  thirteen  million  people.  A  majority  of  
eight  students  knew  that  there  was  a  potato  famine  in  
Ireland  which  killed  over  one  million  people  during  
1845-1847.  Eight  students  thought  we  should  keep  people  
from  suffering  by  aiding  these  countries.  One  student  
thought  it  was  kind  of  dangerous  to  aid  other  
countries.  One  student  said  rich  countries  have  their  
own  problems.           

IV.  SUMMARY AND CONCLUSION:

Sixty-seven  percent  of  the  responses  to  the  factual  
questions on my questionnaire  were  correct.  Therefore,  I  
reject  my  hypothesis  which  stated  that  the  students  
would  answer  seventy-five  percent  the  questions  
correctly.  Students do not know as much about famine and world 
hunger as I thought.

V.  APPLICATION:

I  think  teachers  should  teach  more  about  famine  and  
the  suffering  it  causes.  I  think  that  it  would  
motivate  students  to  bring  in  more  food  items  during  
the  school's  food  drive.



TITLE: Student Opinions About War

STUDENT RESEARCHER:  Teresa Kloepfer
SCHOOL:  Mandeville Middle School
         Mandeville, Louisiana
GRADE:  6
TEACHER:  John I. Swang, Ph.D.


I.  STATEMENT OF PURPOSE AND HYPOTHESIS:

I would like to do a scientific research project on what 
students think about war.  My hypothesis states that the 
majority of the students I interview will be against war as 
being a way to solve a nation's problems.

II.  METHODOLOGY:

First, I wrote my statement of purpose, review of literature, 
and hypothesis.  Then I wrote my methodology and developed a 
questionnaire.  Next, I handed 12 of them out to randomly 
selected students at Mandeville Middle School.  When I got the 
questionnaires back I scored them.  Next, I analyzed the data 
by drawing and creating charts and graphs.  Then I wrote my 
summary and conclusion and applied my findings to the real 
world.  Finally, I completed my report and published my 
abstract in a journal of the student research.

III.  ANALYSIS OF DATA:

I sent 12 questionnaires out and received 11 back.  A majority 
of 10 students did not think that war was a good way to solve a 
nation's problems.  Five students were undecided, 4 said no, 
and 2 said yes in regards to attacking Cuba and Haiti to 
restore democracy.  A majority of 8 students said that there 
are better ways to solve problems between nations than war.  
Half the students knew that 23 major wars are happening in the 
90's today.  A majority of 7 knew that countries have stock 
piled enough nuclear weapons today to destroy the entire world.  
A majority of students did not know that Mexico, Canada, and 
Switzerland do not have nuclear weapons.  The majority of the 
students also didn't know the following countries have or are 
thought to have nuclear weapons: U.S.A., India, Ukraine, China, 
France, S. Africa, Russia, N. Korea, Israel, Great Britain, 
Kazakhstan, and Belarus.  A majority of 8 students didn't know 
that more civilians have been killed in war than soldiers.  A 
majority of 8 students agreed that war should be eliminated as 
a way of solving problems in our world today.  Eight out of 11 
students said that there are no good reasons for war.  Sixty-
five percent of the responses to factual questions on my 
questionnaire were incorrect.

IV.  SUMMARY AND CONCLUSION:

Even though students did not know much about war, the majority 
of them were against war as a way of solving a nation's 
problems.  Therefore, I accepted my hypothesis which stated 
that the majority of students I interviewed will be against war 
as a way to solve a nation's problems

V.  APPLICATION:

I could send my findings to the United States Congress to tell 
legislators there what M.M.S. students think about war. The 
legislators should know that students do not think that war is 
a good thing.



TITLE:  Family Size?  Which Generation Had The Larger Family 
Size?

STUDENT RESEARCHERS:  Mr. Carbone's Math class
SCHOOL: North Stratfield School
        Fairfield, Conn.
Grade: 4
TEACHER:  Mr.  V.  Carbone,  M. Ed


I. STATEMENT OF PURPOSE AND HYPOTHESIS:
   
We want to compare our family size to our parents' and 
grandparents' family size.  We think our parents' family size 
is larger than our grandparents' and our own.

II.  METHODOLOGY:

We are going to count the members of our family, our parents' 
family and our grandparents' family.  We defined family to mean 
the following: We will count ourselves,  brothers, sisters, 
parents, and half brothers and half sisters.
We did not count anyone else living in the home.  

III. ANALYSIS OF DATA:

We found out that the average family size for our families was 
4.1.  The average family size for our parents' family was 6.2.  
The average family size for our grandparents' family was 6.3.

IV. SUMMARY AND CONCLUSION:

We found out that our grandparents had larger families than our 
parents and us.  We reject our hypothesis.  

V. APPLICATION TO LIFE:

Here are some reasons why our parents and grandparents had 
larger families.  First of all, it costs more today to have 
children.  Secondly, it is more expensive today to raise a 
family.  Finally, we do not need big families to help out with 
chores on the farm .

TITLE:  What Do Sixth Graders Think About Writing?

STUDENT RESEARCHER:  Amanda Senules
SCHOOL:  Mandeville Middle School
         Mandeville, Louisiana
GRADE:  6
TEACHER:  John I. Swang, Ph.D.


I.  STATEMENT OF PURPOSE AND HYPOTHESIS:

I would like to do a scientific research project on the 
attitudes and habits of sixth graders about writing.  My first 
hypothesis states that sixth grade students would rather print 
when they write.  My second hypothesis states that sixth 
graders would rather write in pen.  My third hypothesis states 
that more girls like to write than boys.  My fourth hypothesis 
states that boys write faster than girls.

II.  METHODOLOGY:

First, I wrote my statement of purpose, conducted my review of 
literature, and developed my hypothesis.  Next, I wrote my 
methodology.  Then I made my questionnaire and drew a random 
sample from the population of sixth grade students at 
Mandeville Middle School.  Then I administered  the 
questionnaires to the students.  When they were returned I 
scored them and recorded the results on my data collection 
sheet.  Then I conducted my analysis of data.  Finally, I wrote 
my summary and conclusion, applied my findings to everyday 
life, and published my abstract in a journal of student 
research.

III.  ANALYSIS OF DATA:

I handed out 12 questionnaires and 10 were returned.  Four 
girls responded and six boys responded.  A majority of 5 boys 
like to write better in print than in cursive.  Half of the 
girls like to write better in print than in cursive and half 
like to write better in cursive.  Half of the boys like to 
write better in pencil and half like to write better in pen.  
The girls were half and half also.  A majority of 5 boys like 
to write and all of the girls like to write.  A majority of 5 
boys write at a medium speed when writing a story.  A majority 
of 3 girls write at a medium speed also.  A majority of 4 boys 
write daily.  A majority of 3 girls write daily also.  Three 
boys usually write things other than a letter, a Creative 
Writing Project, a Research project, or a diary.  Two girls 
said they usually write a letter.  Two other girls said they 
usually write things other than Creative Writing Projects, in 
their diary, research projects, and letters.  A majority of 4 
boys would rather write with pencil and paper than a computer 
and word processor.  A majority of 3 girls would rather write 
with paper and pencil, also.  A majority of 4 boys say that 
girls are better writers than boys.  All of the girls said that 
girls are better writers than boys.  All of the boys say that 
girls write more often than boys.  Half of the girls say that 
girls write more often than boys.

IV.  SUMMARY AND CONCLUSION:

The majority of sixth grade students write daily, they print, 
and would rather write with a pencil or a pen on paper at a 
medium speed.  The majority of boys don't like to write and the 
girls do.  The majority of all of the students think that girls 
are better writers than boys.  

Therefore, I accept my first hypothesis which stated that sixth 
grade students would rather write in print.  I accept my second 
hypothesis which stated that the students would rather write in 
pen.  I accept my third hypothesis which states that girls like 
to write better than boys.  I reject my fourth hypothesis which 
states that boys write faster than girls.

V.  APPLICATION:

I think that teachers should encourage the students to use the 
computer more often because the students seem to not notice how 
much easier it is than writing with a pencil and paper.  I 
think the students overlook the fun of writing and just think 
of it as homework.  Teachers must find a way to motivate 
students, especially boys, to write.



TITLE:  Student Knowledge of Books and Authors

STUDENT RESEARCHER:  Michael Phillips
SCHOOL:  Mandeville Middle School
         Mandeville, Louisiana
GRADE:  6
TEACHER:  John I. Swang, Ph.D.


I.  STATEMENT OF PURPOSE AND HYPOTHESIS:

I want to find out if 6th grade students at MMS know the 
authors of well-known books.  My hypothesis states that the 
majority of students surveyed will correctly match 60% of the 
books with their authors.

II.  METHODOLOGY:

First, I wrote my statement of purpose, reviewed the literature 
on reading, and developed my hypothesis.  Then I wrote my 
methodology.  Next, I developed my questionnaire. Then I took a 
random sample of 6th graders and sent it out to the twelve 
students chosen.  I then scored the questionnaires when 
returned, recorded my results, and wrote my analysis of data.  
Then I rejected or accepted my hypothesis, wrote my summary and 
conclusion,  and applied my findings to the world outside of my 
classroom.

III.  ANALYSIS OF DATA:

I sent out twelve questionnaires and eleven were returned. A 
majority of seven students knew that Mark Twain wrote "The 
Adventures of Tom Sawyer."  Only two of the students knew that 
Robert Louis Stevenson wrote "Treasure Island."  Only one of 
the students knew that "Robinson Crusoe" was written by Daniel 
Defoe.  Two of the students knew that C.S. Lewis wrote "The 
Tales of Narnia."  Only one student knew that "The Hobbit" was 
written by J.R.R. Tolkein.  Only one student knew that Esther 
Forbes wrote "Johnny Tremain." Three of the students knew that 
"Old Yeller" was written by Fred Gipson.  None of the students 
knew that Robert O'Brien wrote "Mrs. Frisby and The Rats of 
NIMH."  Only one student knew that "Swiss Family Robinson" was 
written by Johaan Wyss.  None of the students knew that Louisa 
May Alcott wrote "Little Women."

Out of one-hundred and ten possible responses from all students 
in the study to correctly match books and their authors, only 
seventeen were correct.

A majority of five out of seven students who answered the 
question, "How important is it to know the authors of the books 
you read?" said it was unimportant.

Three of the students surveyed had read the book "The 
Adventures of Tom Sawyer."  Two of the students had read 
"Treasure Island", and two had read "Robinson Crusoe."  Only 
one of the students had read "The Tales of Narnia", and none 
had read "The Hobbit."  Four of the students had read "Mrs. 
Frisby and The Rats of NIMH", and three had read "Old Yeller."  
Two had read "Swiss Family Robinson", and one had read "Little 
Women."  None of the students had read "Johnny Tremain."

IV.  SUMMARY AND CONCLUSION:

In my research, I found out that the majority of sixth grade 
students at MMS could not match the authors and titles of well-
known books.  Therefore, I reject my hypothesis which stated 
that the majority of students would be able to correctly match 
the authors and titles of well-known books.

V.  APPLICATION:

I could apply my findings to the world by telling teachers to 
put more emphasis on requiring students to know the authors of 
the books they are reading.
