Research Paper
Science Fair Essay
My name is Cole Forgerson, my partner Nick Kraieski and
I have done a science fair project. Our theme was “How does
acid rain affect the growth of plants?” We started the first
week of December. We did all of our research for our project in
the MCAA science lab. Our hypothesis was that the acid rain
would kill the plants. It was a very interesting project, you just
wait and see.
First was the research. Acid rain is any form of
precipitation that is unusually acidic. It has harmful effects on
plants, aquatic animals, roads and/or bridges. Acid rain is
formed by fossil fuels that form sulfur oxide and nitrogen
oxide. When they mix together with the water vapor in the air
they produce forms of sulfuric acid H2S04 and nitric acid
HN03.
The next step was to gather our materials, but they were
already gathered for us. We used 2 spray bottles, lemon juice,
water, paper, a pencil and 2 plants.
.
Next we came up with a method. Nick and I thought of one way
to do the experiment, but Mrs. Throop thought of a better method
for us to do. The plan was for Nick and I to mix the water with the
lemon juice to be our acidic liquid. We put regular water into a spray
bottle and our acidic liquid into a different spray bottle. We labeled
the bottles and labeled the plants. We sprayed the plants for five
days and wrote down how the plants were reacting to either the
water or the acidic liquid.
Finally, we started the project. The first day or two we did
not notice much difference in either plant. They looked pretty much
the same. On day three there was a noticeable difference between
the plants. The plant with the plain water was 4.4 inches tall and had
some flowers and green leaves. The acid plant was only 4.2 inches
and most of the flowers were dying and had turned grayish. By day
four the plain watered plant was still growing and looked healthy and
was sprouting. The acidic liquid plant was looking worse and more
flowers were dying.
In conclusion the acidic liquid plants died. We were happy our
hypothesis was correct. Almost all of the flowers affected by the
acidic liquid died. The water plants were fine and sprouting. The
experiment was successful and the project was awesome.
Conclusion
• Our hypothesis was
right!! But sadly we
had to sacrifice the
plant that we gave
acid in the name of
science!!
