On Saturday, November 21, 2013 Columbia University hosted middle school girls from in and around New York City in the annual Girls Science Day. So what happens when you mix 40 middle schoolers, laser pointers, and fluorescent JELL-O?
The lesson plan was simple enough – in 40 minutes, we would explain the basic properties of an atom and how it relates to fluorescence, explain Snell’s law, give them a JELL-O waveguide, and have them find the critical angle of the JELL-O waveguide.
As it turns out, the best of intentions occasionally crumble (literally!) when children ask “can we touch it?” and proceed to pick up what turned out to be fairly delicate waveguides… Although our JELL-O ended up in several dozen pieces, the shouts of “that’s soooo cool” convinced us that we had a successful demo on our hands. As it turns out, a tray full of JELL-O and tri-color laser pointers make for some pretty neat photos!
Girls Science Day was hosted by Cathy Chen, Atiyah Ahsan, Jelena Marasevic, and Lee Zhu. Approximately 40 students attended the event on Columbia University’s campus.
