Abstract

The purpose of this study was to compare the effect of heat on the production of ozone from ferns. It was hypothesized that if ferns are exposed to temperatures of 80, 85, 90, 95, and 100 degrees fahrenheit, then there will be a greater amount of ozone present. Ferns produce isoprene, a volatile organic compound (VOC), which when combined with nitrogen oxides produce ozone. Five ferns were placed in sealed aquariums to be tested for times intervals of ten days and a month. At the end of the ten days ozone test strips were then used to test the ozone levels. The ozone test strips were unable to read any level of ozone which has caused our experiments results to be inconclusive. The researchers concluded that this lack of ozone may have been caused by multiple reasons. First, the researchers believe that there was not enough nitrogen oxides present for the isoprenes that may have been created to react with and thus produce ozone. The researchers also believe that the ozone test strips used may not have been sensitive enough to pick up the small amounts of ozone that may have been created. The researchers finally conclude that the tests may have created no ozone at all.
