Singing Christmas carols is a long tradition, but it got Cheryl thinking: how does singing work? And is the voice box even a real thing? To answer this, Ryan and Cheryl talk about vocal cords and remember back to Lesson 9 about whistling. We even get Cheryl singing a carol for us! It's never too late to learn about the world around you.  

This is part of the Holiday unit.
