April COACS meeting in Golden features outstanding high school chemistry student and teacher award winners
The Colorado Science and Engineering Fair was held April 10-12 in Ft. Collins. The Colorado Section of ACS supports two awards—one senior and one junior—for chemistry projects. Dr. Joseph DiVerdi heads up the selection process. Chair of the Colorado Section, Dr. Tom Reilly, attended the Awards Program and presented the awards to Nicole Miller from the Junior Division and Bethany Hibbs from the Senior Division. Each student received an award of $100.
Nicole Miller’s project “Know the Glow” sought to answer the question how temperature affects chemiluminescent reactions. She used both commercial glow sticks and luminol solutions. A photometer was built and a program was written to run it. The chemiluminescent reactions were measured at room temperature or in a refrigerator. Her hypothesis was correct for the glow sticks but not for luminol. Nicole represented Ortega Middle School in Alamosa.

Bethany Hibb’s project “Measuring Luminescence in Glow-in-the Dark Objects” was to 1) build a device to measure the intensity and span of light being produced by glow sticks and phosphorescent paint, 2) explore the idea that chemical luminescence lasts longer than light activated luminescence, 3) determine how temperature variations affect the intensity and span of lights being produced, and 4) find out if adding pigment to phosphorescent paint affects its ability to store light. Bethany found that glow sticks lasted longer than paint, temperature did make a difference, and that the pigment added to the glow-in-the-dark paint did make a difference in the paint’s ability to absorb light. Bethany represented Pioneer Christian School in Rocky Ford.
