THE MPEMBA EFFECT
My science
project is about making
ice with different
temperatures of water. I
want to find out if the
starting temperature
affects the amount of
time it takes to freeze.
My hypothesis says that
the cold water will
freeze the fastest
because it is the closest
to the freezing point,
but I have learned that
the warm water can
freeze first, too.
The materials that
I am comparing are hot
water, cold water, and
warm water. I have a
five-step procedure.
My independent
variable, or the thing
that I am changing, is
the
starting
temperature of the
water. The dependent
variable, or the thing
that the independent
variable will affect, is
the amount of time that
the water takes to
freeze. The controlled
variables, or constants,
are the things that are
kept the same. My
constants are the
amount of water, the
same material ice cube
tray and the same
freezing temperature.
My
results
showed that in my first
trial, the cold water
froze first. In the
second trial, the cold
water froze first. My
conclusion tells if my
results supported my
hypothesis and how I
can
use
this
information in the real
world. The data
partially supported my
