Attendees were greeted at the Capitol Theatre by Alexis Bowers and Ava Pollas, recent graduates of Orchard STEM School in Cleveland, who were selling lemonade and cookies from the booth they helped design and build as part of their work with Lemonade Day Northeast Ohio, an entrepreneurial education program. “They not only focused on business and money, but the class also infused infrastructure and engineering concepts,” says Tamera Zelwin, their teacher.
