MINERAL CONTENT OF WATER AND PLANT GROWTH
BY ADRIENNE CARTER
                            

I.  STATEMENT OF PURPOSE OR RESEARCH IDEA:

I want to find out how the mineral content of water affects 
plant growth.  I want to observe the effects of using distilled 
water, tap water, and salt water on plant growth.

II.  REVIEW OF LITERATURE:

Water contains many minerals which are necessary for good plant 
growth.  These minerals include iron, calcium, magnesium, 
phosphorus, potassium, and nitrogen.

If a plant is lacking or has too much of any of these minerals 
the plant may die or not grow into a healthy plant.  For 
instance, if the water has little or no nitrogen or calcium the 
roots will be large, but the leaves will be small.  If there is 
too much or too little potassium or iron the leaves will be 
discolored.

III.  HYPOTHESIS:

My hypothesis states that there will be a significant 
difference in growth of plants watered with distilled water, 
tap water, and salt water.

IV.  METHODOLOGY:

To do my project I am going to grow three pots of seeds, one 
control and two experimental.  There will be six seeds in each 
pot.  I will give them all the exact same amount of light and 
soil.  The seeds will be planted in the same kind of pots and 
be planted to the same depth.  They will be given the same 
amount of water.  The only difference in treatment will be the 
mineral content of the water.  My control seeds will be given 
tap water.  My first experimental seeds will be given distilled 
water and the other experimental seeds will be given salt 
water.  I will record my data for twenty days: when seeds 
sprouted, number of seeds sprouted, height of plants, color of 
leaves, and number of leaves.  I will then analyze my data, 
accept or reject my hypothesis, write a summary and conclusion, 
and apply my findings.

V.  MATERIALS:

3 Flower pots
18 Seeds (6 per pot)
1 Large bag of potting soil
Tap water
Distilled water
Container of salt
Data Collection Form

VI.  ANALYSIS OF DATA:

Four seeds in the control group watered with tap water sprouted 
on days 6, 7, and 8 of the experiment.  The plants grew to an 
average height of 15 centimeters and had a total of 16 leaves.  
Six seeds in the experimental group watered with distilled 
water sprouted on days 7, 10, and 15.  The plants grew to an 
average height of 22 cm. and had a total of 26 leaves.  No 
seeds in the experimental group watered with salt water 
sprouted.

VII.  SUMMARY AND CONCLUSION:

The plants watered with distilled water grew the tallest and 
had the most leaves.  The plants watered with tap water were 
shorter and did not have as many leaves as the plants watered 
with distilled water.  The seeds watered with salt water never 
sprouted.

I accepted my hypothesis because there was an observable 
difference in the rate of growth of plants watered with tap 
water, distilled water, and salt water.  The mineral content of 
water does affect the growth of plants.

VIII.  APPLICATION:

My findings are very important in regard to the loss of our 
Louisiana wetlands and the incursion of salt water farther and 
farther inland into the estuaries and swamps.  If we do not 
stop this terrible loss, all the plants and animals of these 
habitats could die.  I will send a copy of my research to our 
local and state politicians and ask them to help save our 
wetlands.

              (RESEARCH PROJECT ABSTRACT)

TITLE:  Mineral Content of Water and Plant Growth

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


I.  STATEMENT OF PURPOSE AND HYPOTHESIS:

I wanted to determine the effects of using tap water, distilled 
water, and salt water on the growth of plants.  My hypothesis 
stated that there would be a significant difference in the 
growth of plants watered with water of varying mineral content.

II.  METHODOLOGY:

I took eighteen seeds and planted them in the same amount of 
soil.  I planted six per three pots.  I treated all planted 
seeds equally except for the kind of water used.  I used tap 
water in one pot.  I used distilled water in the other pot.  I 
used salt water in the last pot.  I observed for three weeks 
and recorded my data:  color of leaves, height of plants, 
number of leaves, number of seeds sprouted, and when seeds 
sprouted.

III.  ANALYSIS OF DATA:

Four seeds in the control group watered with tap water sprouted 
by day 8 of the experiment.  The plants grew to an average 
height of 15 cm. and had a total of 16 leaves.  Six seeds in 
the experimental group watered with distilled water sprouted by 
day 5.  The plants grew to an average height of 22 cm. and had 
a total of 26 leaves.  No seeds in the experimental group 
watered with salt water sprouted.

IV.  SUMMARY AND CONCLUSION:

In conclusion, because of the visible differences in height and 
number of leaves, I accepted my hypothesis which stated that 
there would be a significant difference in the growth of plants 
watered with water of varying mineral content.  The mineral 
content of water does affect the growth of plants.

V.  APPLICATION:

My findings are very important in regard to the loss of our 
Louisiana wetlands and the incursion of salt water farther and 
farther inland into the estuaries and swamps.  If we do not 
stop this terrible loss, all the plants and animals of these 
habitats could die.  I will send a copy of my research to our 
local and state politicians and ask them to help save our 
wetlands.

THE EFFECT OF GRAVITY ON FALLING OBJECTS OF DIFFERENT WEIGHT
BY RICHARD KAUFMANN


I.  STATEMENT OF PURPOSE OR RESEARCH IDEA:

I want to know more about gravity's effect on falling objects.  
I would like to know if a heavier object falls faster than a 
lighter object or would both objects fall at the same speed?

II.  REVIEW OF LITERATURE:

Gravity is the force that pulls things toward earth.  It is the 
force of attraction that acts between all objects because of 
their mass. 

Scientists say that gravity's pull on a heavier object is 
always much stronger than its pull on a lighter object.  All 
objects fall at the same speed.  That is why both a light 
object and a heavy object will hit the ground at the same time 
when dropped simultaneously from the same height.  Dr. Peter 
Sherman, a physicist, told me to think of it as pushing my dad 
and a small kid up a hill in two wagons.  If I wanted my dad to 
go as fast as the kid up the hill, I would have to push him 
harder.

Sherman, P.  (1992).  Taken from an electronic letter sent to 
me via the National Student Research Center's Electronic School
District on the American OnLine telecomputing network.

IV.  HYPOTHESIS:

My hypothesis states that a heavy object and a light object of 
the same size and shape will hit the ground at the same time 
when both are dropped from the same height at the same time.

V.  METHODOLOGY:

First, I will write my statement of purpose, conduct a review 
of the literature, and develop my hypothesis.  I will then get 
two cans of condensed milk that are the same size, but 
different weights.  One can will be full and heavy.  The other 
can will be empty and light.  Both cans will be the same size 
and shape.  Then my dad will get up on a chair and drop both 
cans at the same time from the same height.  I will watch to 
see which can hits the ground first.  Then I will record my 
observations on my data collection sheet.  Next, I will conduct 
an analysis of my data.  Finally, I will accept or reject my 
hypothesis and write my summary and conclusion.  

VI.  VARIABLES:

The manipulated variable  was the weight of each can.  The 
responding variables were the speed at which each can fell to 
the ground and the moment that each can hit the ground.  The 
variables held constant were the shape of the cans, the size of 
the cans, the height from which the cans were dropped, and the 
moment the cans were dropped.

VII.  LIST OF MATERIALS:

Full can of condensed milk
Empty condensed milk can 
Data Collection Sheet
Chair and carpet

VIII.  DATA COLLECTION SHEET:


WHICH CAN(S) HIT THE GROUND FIRST?

Trials           Both Cans      Heavy Can      Light Can            

1                     X
2                     X
3                     X
4                     X
5                     X
6                     X


IX.  ANALYSIS OF DATA:

My dad dropped the heavy and light cans from the same height at 
the same time.  I observed that both cans hit the ground at the 
same time each time my dad dropped them.  He dropped them six 
times.

X.  SUMMARY AND CONCLUSION:

Both cans hit the ground at the same time.  Gravity is pulling 
harder on the heavy can so that both cans are falling at the 
same speed.  Therefore, I accept my hypothesis which stated 
that both cans will hit the ground at the same time.

XI.  APPLICATION:

If I drop a heavy bag of groceries and a light bag of groceries 
at the same time while helping my mom unload the car, I will 
know to get both of my feet out of the way cause the bags are 
going to hit the ground at the same time.
