The experiment's purpose was to find which
soil would allow the plants to grow the fastest. The original
hypothesis was that the potting soil or other types of dark soil
would be the best. There were six types of soil involved with
this experiment along with a fertilizer Miracle Grow. They were
Limestone, Rocky, Topsoil, Sand, Potting, and Mushroom. The soils
were put into a container which were previously labeled and the
Brassica Rapa seeds were divided among the soils. They were given
a total of a _ of a cup for the next fourteen days. The plants'
growth in the six soils was recorded daily.
Based on the data obtained the highest growth was in the Topsoil
which had an average of 59.25mm per plant then in any other type
of soil used. The next highest growth in plants was in the Mushroom
soil which had an average of 55.875mm per plant. The third was
Potting soil which had an average of 43 mm per plant. This meant
that my hypothesis was partially correct considering that the
darkest soil was the potting soil. The fourth highest growth in
plants was Sand which had an average of 29.875mm per plant, followed
by Limestone which had an average of 21.75mm per plant. Lastly
came Rocky Soil which had an average of 13.625mm per plant. One
effecting factors was that Miracle Grow could help plants grow
faster in the soils. The overall hypothesis of this experiment
turned out to be correct.
