The goal was to inspire future career aspirations, as part of a newly launched initiative called STREAM, which stands for science, technology, recreation, engineering, arts and mathematics, with Columbus Parks and Recreation and Columbus Arts Council. Immediately, it seemed like something they could implement here in Columbus, Walker said. “People don’t know what they don’t know,” Walker said. Henderson said he enjoyed getting to walk students through the exercises and explain his role in solving crimes. Ewing-Johnson said she expects to bring even more students to future STREAM events, because of the benefit they provide to local children.
