The Flipped Science Fair (FSF) flips the traditional science fair format on its head: middle school student judges evaluate graduate students and postdocs presenting their current research. Middle school students learn about cutting-edge research from real Yale scientists in a small-group setting, with plenty of opportunities to ask questions and participate in hands-on demonstrations. The presenters learn to tailor their research pitch to a general audience, with emphasis on keeping things exciting, understandable, and relevant. Our partnership with Pathways to Science, Yale’s coordinated STEM outreach infrastructure, enables long term tracking of student outcomes to measure the FSF’s effectiveness. Flipped Science Fair was inspired by the Kid’s Judge Neuroscience Fair at UPenn.
