6. Make a hypothesis regarding
music and plant growth.
You might have said that since
plants don’t have ears and brains,
they will not be able to process
and respond to the music.
Plant & Music Experiment
Read the experiment description below and answer the questions which follow.
a)
Buy two plants of the same species, in
the same type and amount of dirt.
b) Place the plants in two different rooms
with equal amount of sunlight.

The other plant will not have a radio.
d) Turn the radio on to your favorite
station.
e) Water the plants the same amount of
water at the same time for the next
7. Make a prediction as to what
three weeks.
will happen in this experiment.
f) Make daily measurements (once a day)
You might have said that the
of the height of the plants.
presence of music would result
in no significant differences in
plant growth rate.

8.
Name at least one possible
source of error.
a) Reading the ruler incorrectly
b) Ruler increments may not be
precise enough
c) Not enough trials / samples
Plant & Music Experiment
Read the experiment description below and answer the questions which follow.
a)
Buy two plants of the same species, in
the same type and amount of dirt.
b) Place the plants in two different rooms
with equal amount of sunlight.
c) Place a radio next to one of the plants.
The other plant will not have a radio.
d) Turn the radio on to your favorite
station.
e) Water the plants the same amount of
water at the same time for the next
three weeks.
f) Make daily measurements (once a day)
of the height of the plants.
In reality the data are inconclusive
because of the small sample and trial size.
9. Compare the plant heights.
What conclusions can be drawn?
The hypothesis and prediction
are not supported by the results
because the plant exposed to
music appears to have a
significantly faster growth rate.
