The Power of Mentos
!
The purpose of my
experiment is to see if
Mentos cool down different
liquids. I hypothesized if I
put a Mento in water then
the temperature will drop
because when you suck on
a mento your mouth feels
cool.
!
To c o n d u c t m y
experiment I will need the
following materials: water,
Sprite, orange juice,
Mentos, three cups,
t h e r m o m e t e r, a n d a
measuring cup.
!
Once I had my
materials, I put one cup of
water, orange juice, and
sprite into the same types
of cups. I left the cups out
overnight, then put a
thermometer in one of
the drinks and waited for
five minutes. I wrote
down the room
temperature. Then I put a
Mento into the drink and
checked the temperature.
I repeated with the other
drinks.
!
The independent
variable is the different
types of liquids. The
dependent variable is the
temperature that will
change during the time.
The controlled variable is
the amount of liquid.
!
My results were
that instead of the
temperature dropping it
rose. My conclusion was
that the data didnʼt
support my hypothesis
because I thought the
temperatures were going
to cool down. When the
Mentos dissolved, the
temperature went up.
The way to apply it to the
real world is when a
substance is dissolved
energy is released.
