JoAnn Belferder’s classroom was filled with energy for a lesson on that scientific concept on Nov. 20 at Newbridge Road Elementary School. Working in groups, students made rubber band racers that helped them understand the difference between potential and kinetic energy. 

The young scientists followed instructions to build the racers from two clear plastic cups and tops, along with paperclips, a pony bead, rubber band, straw and tape. They also need a pencil to help stretch the rubber band through two cups. When complete, they spun the straw to twist the rubber band, then put the racer on the floor and watched it move. 

After the contraptions were complete, the class came together to share the observations. They learned that potential energy was represented by the twisted rubber band, which became kinetic energy once the racer was free to move. Students also understood how it was essentially a simplistic version of a car engine. 

The science project fostered numerous skills including collaboration, critical thinking and problem-solving. While every student in each group was assigned a specific role, their racer build wouldn’t be successful without teamwork and efficient communication.
