The awards just keep coming for rising Senior Jaylen Davis’s scientific research.
After earning 1st place for both her written work and her oral presentation at this year’s South Carolina Junior Academy of Sciences conference in April, Jaylen recently learned that she is also one of 11 students statewide (and the only student from an independent school) chosen to represent South Carolina at the AJAS (American Junior Academy of Science) and AAAS (American Association of the Advancement of Science) national meetings in Boston next winter. Just days later, Jaylen received word that she was also one of eight students who are being invited to publish their SCJAS papers in the SC Academy of Science’s online journal.
All of these honors are particularly notable because she was competing with an elite group of almost 300 students statewide who are engaged in advanced scientific research. Jaylen was one of four students who were invited both to publish their work and to attend the national conference; all three of the others attend the SC Governor’s School for Science and Math.
Jaylen’s research project, “The Effect of Chlorine and Bleach on the Color Intensity of Pig Skin,” was developed through her participation in Heathwood’s Honors Science Research program, which is designed to challenge students academically and provide authentic laboratory experiences that prepare them for future success in the sciences. She was one of 47 Heathwood Upper School students who presented their original research at the SCJAS conference this year. Collectively, those students won 20 awards for their presentations.
Jaylen’s research will be published online this fall at http://scholarcommons.sc.edu/jscas/.
The abstract of her project is below.
THE EFFECT OF CHLORINE AND BLEACH ON THE COLOR INTENSITY OF PIG SKIN
The purpose of this experiment is to investigate the effect of chlorine and bleach on pigskin, which is similar to human skin. This project will help people who enjoy pools, to determine the effect of commonly used pool chemicals on their skin. It is hypothesized that if chlorine reacts with pigskin to a greater extent than bleach, it will make the pigskin lighter than the other variable will. 30 samples of pig skin were cut and were measured for light intensity. They were then placed in petri dishes, where they were soaked in the water from the chlorine pool simulation for 45 minutes. After this, they were rinsed, and their light intensity was measured. The chlorine pool simulation consisted of .0198 grams of chlorine, 1 gallon of water and .0181 grams of soda ash. The same process was repeated in the water from the bleach pool simulation. The bleach pool simulation consisted of .0189 grams of bleach, 1 gallon of water and .0181 grams of soda ash. Although chlorine had a greater effect on the color intensity, a T-test showed that the effect was not significant. This proves the null hypothesis, which is that chlorine reacts with pigskin the same as or to a lesser extent than bleach, it will make the pigskin lighter than bleach.
