Each year, NPR puts on its annual Student Podcast Challenge where thousands of young people across the country transform their ideas and stories into audio.Among the middle school finalists were two students from High Tech Middle Media Arts in Point Loma, who produced a podcast about growing up in a multiracial, multiethnic family and embracing cultural ties.Wednesday on Midday Edition, we hear about the students' inspirations and how they captured the experiences of those with mixed backgrounds in their podcast.Guests:Abby Dutra, student, High Tech Middle Media ArtsOryan Navarrete, student, High Tech Middle Media ArtsRebecca Carnahan, 7th grade humanities teacher, High Tech Middle Media Arts
