Last Friday evening, about 115 elementary-school students displayed their inventions and results of scientific inquiry at the 15th anniversary of Cabot Elementary School’s Invention Invasion — an event sponsored by the Cabot PTO and faculty. The student inventors were thrilled to be interviewed by enthusiastic undergraduates from Boston University’s Technology Innovation Scholars Program, who visited each display to learn how things worked, to ask where these ideas came from, and to marvel at the results.  In addition, the LigerBots demonstrated their previous-year’s award-winning robot, and the New England Section of the Optical Society of America demonstrated a giant kaleidoscope, light pens, heat-vision cameras, and prisms.  Click on the photo below for a closer view.
