Moldy Bread
!
Im
doing
an
experiment on growing
mold on different kinds of
bread. My question is:
Which kind of bread will
get moldy first? My
hypothesis is that the
bakery Italian bread will
get moldy first.
The materials that I
am using are two pieces
of rye, wheat, multi-grain,
and bakery Italian bread,
eight Ziploc bags, and a
marker.
My procedure is:
step 1. Label the bags
with the bread names.
step 2. Put one piece of
each kind of bread into
the bags. step 3. Place
each bag in the same
place, same conditions,
and room temperature>
step 4. Check and
record each day until
you decide to end the
experiment.
The independent
variable is that each
kind of bread has a
number
of
preservatives. The
dependent variable is
the mold because the
mold affects the bread.
The controlled variables
are
the
room
temperature, sealed up
bags, and same amount
of light.
The results are
bakery Italian bread was
the bread that got moldy
first. My data supported
my hypothesis because
bakery Italian bread got
moldy first. I learned in
order to keep food fresh
food
you
need
preservatives in your
food.
