Surface Ozone
This experiment focused on the question, how does the level of cloud cover affect the amount of ozone present? If there are more clouds in the sky, then there will be higher levels of bad ozone in the troposphere, because the clouds will prevent the ozone molecules from escaping higher into the atmosphere. The independent variable tested is the time. The dependent variables that will be measured are the ozone, clouds, current temperature, wind, air pressure, and relative humidity. The controls for this experiment are the time of the testing, and the materials- Zikua Ozone Testing Kit , a DIY Wind Direction Instrument, an Outside Instrument Shelter, (contains an alcohol thermometer and a Digital Dual Sensor Thermometer) (SN 89212), a Sling Psychrometer, Barometer, and a GLOBE Cloud Reading Chart. The ozone, clouds, current temperature, wind, air pressure, and relative humidity were all measured twice a week over a month and will resume in the spring. In conclusion, it was found that the more clouds there were the less ozone there was, and the less clouds there were the more ozone there was. In future experiments current temperature, wind, relative humidity, and air pressure would be added to see how they might affect the ozone reading. Keywords: ozone, clouds, current temperature, wind, air pressure, relative humidity

Dear Anna, I congratulate you on your work. I learned a lot. Hope you will continue to work on projects like this. Hope you will present your reserch to your classmates or local community. Even hypothesis was not supported by the data, this is how we learn trough research. Wish you all the best.
Dear Ms. Mezga,

Thank you so much for looking into my project! I appreciate all of the ideas that you shared. I have presented most of my data to my class during our school science fair. I will also be attending Bay Day in May to present my project to the community at our local college. I also presented to various judges and students from other districts about my project at YCSEF, our regional science fair. My teacher and I were very surprised that my data did not support my hypothesis, but it did help as I was trying to figure out why it was not supported. Through revisiting my research and researching more, I finally made the connection as to why this was, and it actually really made sense. I think it took my data showing me something different for me to look at the research in a different way to make that connection. Thank you for looking at my presentation and sharing your expertise with me!

Thank you,
Anna Willard
