The Effect of Various pH levels on the Survival of Paramecium multimicro nucleatum
By Mahmood SaboungiSlide2
What is paramecium multimicro nucleatum?
Paramecium is a
single-cell eukaryotic
organism
.
It
is a genus of Protozoa, also related to amoeba, and flagellates
.
It
is also a member of the phylum ciliophora
.
Paramecium are heterotrophs which means their common form of prey is bacteria. A single paramecium has the ability to consume 5,000 bacterium a day, they also feed on yeast, algae, and other small protozoa.
Paramecium live in warm fresh water environments such as rivers and lakes.Slide3
Purpose
The purpose of this project is to determine which level of pH in distilled water will affect the survival rate of
Paramecium. In other words finding a range of pH levels that paramecium can survive in.
Vinegar will be added to the distilled water to make the water alkaline (
basic
).
Since paramecium can be found rarely in the human body, in the gastrointestinal tract, interest in paramecium and this subject was the reason for this topic, along with my interest in any type of organisms.Slide4

Procedure
1. Obtain all materials.
2. In order to determine how much vinegar and how much baking soda is needed to change the pH level, test the pH level of distilled water with each varying quantity of vinegar and baking soda applied in the distilled water.
3. Make a data table of the amount of vinegar and baking soda and their specific outcomes of pH levels by how many drops and squirts from every substance.
4. Set up the microscope and the laptop computer.
5. Start by adding 45 milliliters of distilled water in the first petri dish.
6. Then add .025 of a milliliter (one drop) of vinegar to the petri dish.
7. Stir the contents in the water until the vinegar is fully dissolved.
8. Place .05 milliliters (2 drops) of the solution on the microscope slide, then add .025 milliliters of the paramecium from the jar onto the microscope with the solution, it should be easy to count 15 paramecium with your naked eye (the amount of paramecium you should put on the slide).
9. Observe what you see in the microscope eye, and on the laptop.
10. Record and average the data.
11. Take a picture of the paramecium.
12. Repeat this process 2 more times.
13. Clean pipette for the vinegar to remove all the excess vinegar.Slide6
Procedure continuation
14. Repeat steps 5-10 but adding 2 drops, or .05 milliliters of vinegar this time, and then 3 drops of vinegar, and so on until 5 drops (use a different petri dish for every solution, or every time your adding another drop of the substance).
15. Repeat steps 4-13 but this time use baking soda for every thing that was vinegar.
16. If needed, keep adding squirts of baking soda to the solution until the paramecium dies
.
17. Record and average the data.
18. Make a data table of all observations.
19. Graph the averages of the final productivity on the survival rate of paramecium. Slide7

PicturesSlide9
The control that was
utilized in this experiment was distilled water without
added substances
. This
experiment was
to identify
the
range of
pH level that paramecium could survive
in. Five pH levels for vinegar and seven pH l levels for baking soda were reached. The paramecium
died
when placed
in
the 1
drop
vinegar, along
with
all
the
other
drops
of vinegar.
In
the control,
the paramecium were very
hyper and stayed alivefor the entire 20 minute duration viewing time. In the baking soda until 5 squirts, the paramecium were overly and exceedingly hyper. When placed in the water with 10 squirts, they became sluggish and slow but remained alive for the entire duration viewing time. When placed in the water with 15 squirts, they died after 4 minutes.
ResultsSlide10
Conclusion
The hypothesis of this experiment was the Paramecium Multimicro nucleatum will not
survive
in water at pH levels lower than 4 nor higher than 8. The paramecium died
instantly
when placed in the water that had a pH level of 3.97 and lower, The
paramecium
thrived in water that had a pH level up to 8.13. The paramecium was
sluggish when placed in the water that had a pH level of 9.07 but remained alive for
the entire duration of viewing them. However, when placed in the water that had a pH level of 10.03 the paramecium was very slow moving and died within 4 minutes. This concluded the paramecium does not survive in water of 4 pH level or lower, nor in water of 10 pH level or higher.
The
hypothesis therefore was partially proved
because
the paramecium did not survive in water with pH level less than 4. However,
the
hypothesis was also partially disproved because the paramecium did survive in
water
with pH level greater than 8 but only up to 10.Slide11
Application
Every person in the world distastes and fears bacteria. Bacteria make
you
ill, they
may
carry diseases, and they are contagious. Humans
always
think of ways to
eradicate bacteria. Paramecia apply to this real world because they can terminate any
sort of insalubrious and harmful bacteria. A single paramecium can consume 5,000 bacterium a day. This proves how important it is to assure the paramecia thrive
in order to
wipe
out a
great
deal of bacteria from the face of this
Earth. Regrettably
, a
paramecium’s
life
is always
at risk.
There
are
some
areas of
freshwater
that may be highly malignant to their sort. Polluted water is considered exceedingly acidic. Paramecia do not have the ability to survive in acidic water. The purpose of this experiment was to find the range of the pH level of water that paramecium can survive in. As pollution is acidic, there is a great need to control it from entering Earth’s eco-system, in order to maintain ideal water conditions that paramecia can survive in. Slide12
