UConn Chemistry lecturer Dr. Clyde Cady directed several dozen budding scientists through two interactive demonstrations of “Electrons in Motion” during last month’s Science Salon Junior event. Science Salon Junior, held during UConn’s 2017 Family Weekend, featured exciting experiments for children ages 5-12. Throughout the event, Cady and Greg Bernard, CLAS Director of Alumni Relations, led a team of chemists that included Associate Professor Dr. Mark Peczuh, graduate students Svetlana Gelpi and Xudong Wang, and undergraduate student Shahan Kamal. In one demonstration, Salon Junior participants electroplated zinc onto copper pennies and then “brassed” them by heating them in a flame. In the other demonstration, students prepared solutions and observed the phosphorescence of a ruthenium (III) bipyridine complex. As the lights went out to observe the phosphorescence, one participant quipped, “Now I see the light!” Cady’s perspective on the event is equally profound, reflecting, “I hope we illuminated the power of chemistry for our young scientists and polished their interest in STEM so that it was just as bright and shiny as the brass pennies we made.”

These fun, kid-friendly demonstrations were part of the inaugural Science Salon Junior program, an off-shoot of UConn’s successful Science Salon events.
