Fruits and Vegetables Power the
World
The purpose of my
experiment was to
find out what fruits
and vegetables
have the most
power. I
hypothesized that a
potato will have the
most power and an
onion will not have a
lot of power but they
would all at least
power the clock.
!
To conduct my
experiment I needed
the following
material: volts
meter, potato, onion,
tomato, lemon and a
potato clock. Once I
had my materials, I
started making a
graph that showed
how much power
they all had.
!
The
independent
variable was the
fruits and
vegetables. The
dependent variable
is how much energy
they produced. The
constants/controlled
variable was the
potato clock.
!
In the end my
results did not
match my
hypothesis because
I thought the lemon
would do good and
it did. I was right
about the onion
because it did bad. I
learned that a potato
and a lemon are
good to be used as
a source of energy.
