| The Effects of Weather on
Plants |
by Jonathan and Andrew
Gage Jr. High School, Gage, Oklahoma
(presented at the 1999 Earthstorm Science Fair)
Jonathan and Andrew are both 14.
We both enjoy playing sports. We attend Gage Jr. High School. We thought of this
project and worked from there. We chose this project because we enjoyed working
with Mesonet data and doing measurements.
Our project was to determine the effects
of weather on plants. We measured and compared the effects of weather on the
growth of Coleus plants and their root systems. Four plants were left inside
in a sunny window. Two plants were left outside all the time. Two plants were
monitored and brought in during bad weather. We determined the average temperature
and wind chill at which those plants were able to survive. The average temperature
and wind chill was downloaded, made into tables, and graphed. We also analyzed
the effects of weather on germination and the movements of water through the
xylem.
The weather did have a definite effect on the growth of the plants. The
4 plants left inside grew the largest by an average of 3 centimeters. The 2 plants
left outside did not survive. The 2 plants that were monitored and brought
inside sometimes did survive. Weather also affected the seeds in the germination
chamber, but the weather did not seem to have significant effect on the movement
of water through the xylem. All Mesonet data were downloaded and graphed. Also,
data collected on the growth of plants and mass of plants regarding xylem were
graphed and analyzed.
We learned how to use Mesonet data and the effects of
weather on plants. We would like to thank Mrs. Chance for helping us. Yes, we
think we would do another project. We would also like to thank the people at
OU for the Mesonet data. |
