Preschoolers at Southampton Road Elementary School turned some of their favorite books into science and technology projects on Tuesday in “It STEMs from a Story.”

The event was based on stories from Massachusetts-based author and illustrator Jan Brett. Three- and four-year-olds in Colleen Murphy’s and Christina Doherty’s classrooms visited activity stations staffed by fourth graders at the school. STEM stands for science, technology, engineering and mathematics.
