Over 30 top high school students from around the world, attending the Penn Summer Science Academy (PSSA) at the University of Pennsylvania, had a memorable learning experience July 10 at the Simeone Foundation Automotive Museum in Philadelphia. With the Museum’s famed collection of classic racing cars as a backdrop, the students – who came from ten countries around the world as well as the U.S. – gained firsthand knowledge of the principles of mechanics using two very low tech objects: a bowling ball and a broom.
