Lisa Chasse does the Chicken Dance with Martel Elementary School students during the fifth annual Dancing for Fitness event at Shaw’s Supermarket in Lewiston on Friday. Three hundred students danced to six songs for the benefit of being well, said Chasse, an educational technician at the school. “It’s all about fighting obesity,” she said. Shaw’s closed a large portion of the parking lot to accommodate the dancers. Go to sunjournal.com/marteldance to see a video of the students and staff dancing.
