The purpose of this experiment
was to determine how temperature affects the size of raindrops.
A 20.32 by 20.32 cm pan with 4.6 cm of flour in it was taken outside
during a rainfall. The raindrops that fell in the pan formed tiny
pellets of dough in the flour. The pellets of dough were then
taken inside and baked in the oven at 37.78 degrees Celsius for
five minutes. After five minutes, the dough pellets were removed
from the oven and measured individually with a metric ruler. Ten
raindrops were measured each day. The ten measurements were then
added up and divided by ten to find the average raindrop size
for that day.
Four different test days
were used during the course of the experiment. On the first day,
the temperature was 17 degrees Celsius and the average size of
the ten raindrops measured on that day was 1.9 mm. On the second
test day, the temperature was 14 degrees and the average size
was 2.3 mm. On the third day of testing, the temperature was 11
degrees and the average size was 3.5 mm. On the fourth day, the
temperature was four degrees Celsius and the average size of the
raindrops measured was 3.8 mm.
After completing this experiment,
it was found that as temperature decreased, the size of the raindrop
increased. This meant that it had an inverse relationship that
was consistent throughout testing.
