What is the affect of different liquids
on the growth of plants?
By Alex Childers
Prediction
I thought Mountain Dew would grow the most and Coffee would grow
the least. I thought this because Mountain Dew has the most sugar, and
plants eat their own sugar but I thought actual sugar(or corn syrup)
would act as a substitute for plant sugar and help the plant grow
more.Therefore,Mountain Dew’s sprouts would be the longest and
Mountain Dew would have the most sprouts.

Procedure
1.Gather cups, flower seeds, soil, and different
liquids.
2. Scoop 2 cups of soil into the cup you will use
for that different liquid. Bury seeds an 8th of
an inch in the soil.
3.Label each cup.
4.Water plants when they look dry with 15
millimeters of the liquid that cup belongs to.
5.Observe after watering the plants
My changed variable is the liquids; I have
Mountain Dew, Coffee, Water, Diet Coke, and
Vitamin Water.
My variables kept the same are the amount of
liquid they each get, the amount of sunlight
they each get a day, the type of soil, the
amount of soil, and the flower seeds.
My measured and observed variable is the
growth of the flower and how many sprouts
there are.

CER
Claim:
Diet Coke is the superior liquid to water seeds with.
Evidence:
My data table shows that the seeds watered with Diet Coke were the first to
sprout, sprouted the most seeds, and grew the tallest. I noticed that Vitamin
Water and Mountain Dew had (and still have) no sprouts. Coffee started as third
but soon caught up to be second and grew a total of 3 and 8/10 cm. Water
placed second, but then fell into third and grew 2 and 7/10 cm . Diet Coke had
an excellent growth and stayed at first the whole time with a total growth of 6
and 8/10 cm!
Reasoning:
I know plants need liquids , air , soil and sunshine to complete the process of
photosynthesis. I think Diet Coke grew the most maybe because marigolds are
hearty plants and reacted more towards the Diet Coke. Also because Coffee
came in second and has the second most amount of caffeine and Diet Coke has
the most so I thought that had something to do with it. Mountain Dew and
Vitamin Water had the most sugar and didn’t grow so I think that the sugar kept
the plants from growing. As you can see Diet Coke is the best liquid to water
plants with.

Final pictures of
growth!
Mountain Dew and Vitamin
Water didn’t get a picture
because they were in the
garbage. I did observe that
they still did not have any
sprouts.
Thank you for watching!!!
