Cooper Second Graders Study Balance and Motion
A second grader from Kelly Brotz's classroom at Cooper Elementary School, is holding a mobile of his own creation that he made during their Balance and Motion science unit. The students learned how to get an object into a stable position by placing counterweights below the balancing point. During the lesson students were given two mobiles to create using straws, rubber bands, paperclips and index cards and then were challenged to come up with a mobile of their own that would balance in a stable position.
