Partridge 5th Graders Learn About Machines

  • The Power School Class came to Partridge Elementary’s 5th grade classrooms on Feb. 13 to demonstrate three machines: a ring launcher, a Ruben’s tube, and a Wankel engine. Fifth graders rotated through each of the demonstration stations, listening as the Prime Power School soldiers taught the basic science and engineering behind each machine. After the presentations, the students engineered bridges and egg holders out of various common household items. The bridges had to support the weight of a dictionary and the egg holder had to be stable enough to hold a raw egg.
