| Ozone Defence |
by Dedi Snell
Lowrey K-8 School, Tahlequah, Oklahoma
(presented at the 1998 EarthStorm Science Fair)
My name is Dedi Snell, I’m
fourteen, and I go to Lowrey School near Tahlequah, OK. The name of my project
was “Ozone Defense”. It was
connected to another project at our school called “The Penta Project”.
I wanted to see how local weather conditions affected the ozone pollutants
in the environment.
I studied Mesonet weather data from the Bixby Mesonet site
(in south Tulsa County) and the Tahlequah Mesonet site. The Bixby site is near
a large metropolitan area and the Tahlequah site is in a very rural setting.
Using a mixture of potassium iodide paste at several sites in town and at rural
settings, I was able to figure out how many ppb’s (parts per billion)
of ozone particles were present at a given site. By using Mesonet weather maps,
I was able to tell what parameters most affected ozone levels at given sites.
This information will make it easier to predict bad ozone days by comparing
pollutant levels and weather forecasts.
I received help from OU Mesonet scientific
mentors, KOTV Channel 6 weatherman Jim Giles, and the Tulsa County Health Department.
I was very excited to win first place in the 1998 EarthStorm Science Fair.
In May, I displayed my project for Undergraduate Research Day at the State
Capitol and met my local legislators. I have learned a lot about meteorology
and plan to attend college at the University of Oklahoma. I learned how everyday
weather affects all of our lives, and how better forecasts in the future could
help people, especially those with asthma or other breathing problems. |
