Guam –  St. John’s School ninth grader Danielle Stephenson-Threatt and seventh-grader Nicholas Camacho were named Overall Winners in the Division 4 (high school) and Division 3 (middle school) age groups, respectively, at the 35th Annual Island Wide Science Fair held at the University of Guam.  Science fair winners were announced at the awards ceremony on Monday, May 27.

Danielle Stephenson-Threatt was the Division 4 age group Overall Winner, for her project, “Antimicrobial Properties of Local Medicinal Plants against E. coli.” Stephenson-Threatt won this year’s grand prize that entitles her to attend the NASA-sponsored Space Camp/Academy in Huntsville, Alabama, via Delta Airlines with help from MEC and IP&E, the major sponsors of this year’s science fair.  

Nicholas Camacho was the Division 3 age group Overall Winner for “Allelophathic Inhibition by the Leaves of Vitex Parviflora.” Camacho will receive a computer.  Danielle Stephenson-Threatt was the Division 3 age group Overall Winner the previous year.
