Preserve the Apple
!
The purpose of my
experiment is to find out
which liquids can preserve
apples. My hypothesis is: If
I cut an apple and put it
into milk, water, and lemon
juice, then it will not
become dark because the
exposed area has been
covered.
!
The procedure of
my experiment is: First, I
will cut an apple into eights.
Then, I will put an eighth of
an apple into milk, water,
salt water, lemon juice,
orange juice, sprite, diet
coke, and one sitting in a
cup with nothing but air in
it.
!
The materials I
need to complete my
experiment are: an apple,
orange, lemon juice, salt,
regular water, milk, water,
sprite, diet coke, 8 cups, a
knife, and a cutting board.
!
The independent
variable is the different
liquids that I stuck an
eighth of an apple into
(listed above).The
dependent variable is the
green and brown spots
that were on the apple
after they spent sometime
in the liquid. The constant
is the fact that I used the
same kind of apple in my
experiment.
!
In my experiment
the results showed that
the lemon juice and
orange juice are the only
liquids in my experiment
that are preservatives.
!
I came to the
conclusion that my
hypothesis was 33% right.
I learned that if I cut an
apple open and then had
to go somewhere
(unexpectedly or
expectedly) then I could
stick it into lemon or
orange juice, and come
back to it later.
