The 2008
Arkansas Science and Engineering Fair was held at the University of Central
Arkansas on April 4, 2008. Representatives from the University of Arkansas for
Medical Sciences (UAMS), College of Medicine, Rural Medicine Student Leadership
Association (RMSLA) judged science projects for the Arkansas Mentor Award, one
of many specialty prizes at the science fair. The Arkansas Mentor Awards
are sponsored by the UAMS Regional Programs and the Arkansas Farm Bureau. These
specialty awards are aimed at projects that may improve the health and
well-being of rural Arkansans.
1st
Place ($125): Bayley Shields, a 9th
grader from Alpena High School. Her project, To Preserve or Not to Preserve, studied the effectiveness of sodium benzoate, a preservative commonly found in
foods, as an insecticide. She found that the sodium benzoate is effective in
killing fruit flies and corn worms, and subsequently calculated the most
effective dose and mixture of sodium benzoate to be used as an insecticide. She
hopes that this may lead to the development of a more consumer-friendly, less
toxic future insecticide for the agricultural industry.


2nd
Place ($75): Emily Smith, an 11th
grader from Alpena High School. Emily's
project entitled, The Effect of Thimersol on Hamsters, Phase
II, investigated
the effect of thimersol, a preservative found in many childhood immunizations,
on the birth rates and abilities of the hamsters exposed to the substance to
navigate a maze. She also tracked how much of the thimersol was excreted by the
hamsters and how much each hamster retained. She discovered that the thimersol
did have a negative impact on the hamster's ability to navigate a maze and the
birth rates of hamsters born to mothers exposed to the thimersol. She hopes
that this research could shed light on the debate linking Autism to thimersol
found in many childhood vaccines.
3rd
Place $50): Mandy Burkhart, a 12th
grader from Alpena High School. Her project entitled, Phosphoric Acid vs.
Sugar, Phase IV, explored the effects of phosphoric acid and sugar on teeth
strength and enamel. While she found that both sugar and phosphoric acid alone
weakened teeth enamel, she discovered that the combination of the two, as
present in most soft drinks, significantly decreases the strength of teeth.
Judges
were: Paige Lawson, M2 and RMSLA co-president; Aaron Mitchell, M2 and RMSLA
co-president; and Rebecca Mitchell, 4th year pharmacy student.
