Why do some animals play - and some don’t? That’s what Meredith wants to know. In this special collaboration with Outside/In, we investigate how and why animals - and people! - of all shapes and sizes play. Play scientists Junyi Chu and Jackson Ham help us ask the important questions like: Can you tell an octopus to play? And what can rats teach us about why taking turns is important? It turns out that play is serious science!  This episode is a collaboration with Outside/In from New Hampshire Public Radio, and co-reported with executive producer Taylor Quimby. Taylor recommends the show for older kids and teens, and suggests these family-friendly episodes for listening together.
