Conclusion: The purpose of this experiment was
to measure how high a frog jumped. We
predicted that the frog would jump the highest
when it was placed upon concrete. In order to
test this, we measured how high a frog jumped
multiple times. Our data showed that the frog
jumped the highest when it was standing on a
concrete surface. This was what we thought
would happen.
There were no sources of error, unless
we measured the frog’s jumping height
incorrectly. The frog also could have been tired
after jumping so many times, and not jumped
as high sometimes. This has no real-world
connection because frogs don’t live on concrete
and Styrofoam.
Conclusion: The purpose of this experiment was
to compare how high a frog could jump when
placed onto various surfaces including grass,
styrofoam, concrete, glass, and sand. We
believed that a frog would jump the highest
when placed in the grass, because grass is
springy and might give the frog a little ‘boost’
when it began to jump. In order to test this idea,
we built several enclosures with different
surfaces covering the bottom of the chambers.
Our test subject frog was placed into each
chamber, and using time-lapse photography,
the frog’s jump height was measured against a
meter stick taped to the wall of each chamber.
Our data showed that after multiple trials, the
frog jumped the highest when placed upon
concrete, and had the lowest jump height while
standing on glass. This refuted our hypothesis,
which stated that the frog would have the most
success with jumping in the grass enclosure.
Possible sources of error in this
experiment included the meter sticks on the
wall of the enclosure, possible frog fatigue, and
the quality of the surfaces that the frog started
upon. The meter sticks may not have been
perfectly straight due to human error, and the
frog may have gotten tired after jumping so
many times in a row. There is also a possibility
that the materials we used to build the frog’s
launch pads were not of good quality. Using the
data from this experiment, we could infer that
friction between a frog’s legs and the surface it
is standing upon might impact the ability of the
frog to jump in some way. This is because
concrete and glass are rough and smooth, so it
would likely be beneficial to test frog jumping
height on more rough and smooth surfaces.
