PERLA VILLALOBOS
Bottle Organ
!
The purpose of
my experiment was to
find out if the sound of
the liquid was going to
be a higher pitch or a
lower
pitch.
I
hypothesized that the
sound was going to
change by the amount
of liquid thatʼs in the
glass.
!
To conduct my
experiment I needed
the following materials:
liquids, six glasses,
metal spoon, and
measuring cup. Once I
had my materials, I put
some liquid into the
bottle and once the
liquid is in the glass I
tap it with the metal
spoon and hear the
sound that it makes. If
itʼs a high pitch or a
lower pitch and it also
might vibrate.
!
The independent
variable was the type of
liquid. The dependent
variable is the amount
of liquid thatʼs in the
glass. The constants/
controlled variable were
the same glass.
!
In the end, my
results supported my
hypothesis because in
my results it was similar
to my hypothesis and in
my results it answered
my question. I learned
that if you put different
amounts of liquids in a
glass and hit it with a
metal spoon it will make
a high sound or a low
sound.
