Sat. 3/19, 9a: The Children's Hour bounces into spring with a show dedicated to celebrating the lengthening daylight and warming weather, and saying farewell to winter. What makes it winter one day and spring the next? We'll discover the science of springtime. Plus, find out how you can get a scholarship to Hummingbird Music Camp with the Sky Velvet Vassar foundation. With great music, the KUNM Kids Birthday Club, a family events calendar and so much more, spend an hour with the KUNM Kids!
