Introduction and Background
Packaging is an important method of
preservation (keeping something safe).
Many times if a package is damaged at the
store, it will not be purchased. Proper
packaging is important for healthy
Green packaging will decompose, but plastic
and metal stays on earth for years. For
example, tissue, cotton balls, grass, paper,
and wood are green materials which are
useful for packing.
Eggs are very fragile so therefore in order
to keep them safe you would need to use
proper packaging materials to insure
The purpose of this experiment is to test the
effect of cotton and other renewable
materials as cushions for a dropped egg.
We are constructing a package for an egg
that is being tested for damage as a result of
being dropped from a height.
Cotton balls will be more effective than egg
crate packing in protecting an egg in free
fall. The egg will be contained in a
cardboard box with dimensions less than 3”
by 3” by 3”.
Our cardboard package was constructed
according to the supplied rubric. Only
renewable materials were allowed in this
The package containing the egg was first
dropped from approximately 6 ft. Only
intact eggs from the lower elevation were
allowed to compete at the higher 25 ft
In this investigation, the timeline was as

Initial assembly began late September.
We tested our product on Mid-October.

The sealed protective box was constructed
according to the rubric. We started testing
from the lower section of the bleachers,
extending the arm straight out before
releasing. Eggs which survived the first fall
were then tested at the higher section of the
Data and Data collection:
We collected data in the following manner:
Cotton was used more frequently than any
other renewable resource.
Figure 1.2 attached, shows that in the egg
drop trials of cotton balls eight cracked on
the first trial, four cracked on the second
trial, and only 5 were safe at both heights.
On the egg crate trial the egg cracked on the
Our project which had cotton balls to protect
the egg cracked on the second drop of the
trial. Also, the same results happened with
the egg crate, however only one group used
Dropping the boxes with the testers arm at
the height of the fence would standardize the
distance of the drop.
It would be said that cotton balls are better
when protecting the egg, however one
would have to perform the same amount of
egg crate trials to fully evaluate the effect of
each packing materials on preventing
breakage of the egg.
The data did indicate that there were five
cotton ball trials that were successful at both
heights in protecting the egg.
The hypothesis that cotton balls are more
effective than egg crate at protecting the egg
from breakage is not fully supported in this
experiment. More testing would be
