An eXploration of elastic potential energy for first graders
Self-made tape measurers hang suspended from the ceiling, stretched to reach the tops of the tables with 10cm increments clearly marked. Kids take turns vertically propelling the balls using student-made ball-launchers. This was the scene in the eXploration station this past month when first graders from Fall Creek Elementary School participated in bimonthly visits to Xraise at Cornell during the past school year. Teachers Chris Bell and Abigail Bokaer brought their students, sometimes riding the bus and sometime walking up the hill, to participate in these science investigations.
