Experiment
For our experiment we placed a russet
potato in a cup of water. Next we placed on cup of water in a refrigerator and
left the other in room temperature of about 70 degrees Celsius. The factor for
our experiment is the water temperature, which will determine weather or not the
potatoes will grow quickly, slowly, or not at all. The experiment has taken
place over a four-week period and has shown decent results. The strangest of the
occurrences was that the results fed back to us were not of those that we
predicted.
The way that our experiment worked was
that the potatoes were expected to sprout roots in at least two weeks, and we
were shocked to realize that the potatoes, or rather the room temperature
potato, sprouted roots only four days into the experiment. Over the first week
we noticed little development. The first potato to grow was the room temperature
potato. It sprouted little roots at first, but over a few more days, the
potato’s roots measured-out to about a millimeter in length. The refrigerated
potato would not yield results until Tuesday of the second week. The roots of
the refrigerated potato were not very long and were very thin.
The second week was by far the most
productive of the four weeks we conducted our experiment. The reason for this is
because the roots of the room temperature potato grew 1.5 millimeters more, and
the refrigerated potato grew one millimeter more. The refrigerated potato grew
another half inch on Thursday and still remains far more unproductive. We
believe that the reason for this stunted growth has both to do with the far
colder refrigerator’s artificial coolant, which may posses, an adverse effect on
the growth of the potato.
The third week was steady as the potatoes continued
to grow. The room temperature potato’s roots grew another 2mm and the
refrigerated potato grew only 1mm. The Fourth week concluded that the potato in
Room temperature water grew the best, how could this be? If potatoes are
supposed to grow in temperatures from 50 degrees to 70 degrees; then the
refrigerated potato should have grow more (see analysis). The potato in
refrigerated water grew another millimeter and the room temperature water grew
another two millimeters. So in conclusion, the room temperature potato’s roots
grew a total 2.5 millimeters and the refrigerated potato grew only 2
millimeters. So the best temperature to grow potatoes in water is at a room
temperature of 65 degrees.
