for more than 2500 years.

grow throughout the world.

under cloth or plastic?

Growth Patterns
Plastic
-Had an
increased
growth
pattern.
-Grew 2.6
centimeters.
Cloth
-Increased
steadily
then fell.
-Grew 1.91
centimeters
then,
decreased
0.75
centimeters.
Conclusion
Our hypothesis was
incorrect. It turned out
that instead of growing
better under the cloth, It
grew better under the
plastic. Compared to
the lettuce under the
cloth, the lettuce under
the plastic seemed like
Jack’s beanstalk.
Analysis
In the process of this
experiment, we learned
that lettuce, or plants as
a whole, grow better
under plastic than cloth.
In the future when
growing lettuce in the
Winter, we will, from
this experiment, know
to cover the plants with
plastic.
Personal Reflections
Irina-Lettuce can get frostbite.
Justice-Lettuce grows better
under plastic than under
cloth.
Helen-Growing lettuce is harder
than it seems.
Talia-Lettuce can grow in the
Winter.
Claire-Lettuce doesn’t grow as
fast in the Winter as it does
in other seasons.
