We’re used to seeing dogs and cats play with toys or get the zoomies... but do animals like rats and bumblebees play too? What is animal play for? How do scientists even decide what counts as play?
Today, we’re taking a serious look at goofy behavior. We’ll discover the five-part checklist that many scientists use to recognize play in nature, and find out why taking turns is so important for healthy brain development.
This episode is a collaboration between Outside/In and Tumble, the science podcast for kids.
Featuring Junyi Chu and Jackson Ham
Produced by Lindsay Patterson, Marshall Escamilla, and Taylor Quimby. For a transcript and full list of credits, go to outsideinradio.org.

What is a forest for?
In New Hampshire, the most beloved swath of public land is the White Mountain National Forest. People interact with it as they would a national park – hiking, swimming, camping, and more. But a national forest is NOT a national park.
The difference comes down to a fundamental concept: the “multiple-use” land mandate. In the WMNF, you’ll find parts of the forest preserved for wildlife conservation, recreation, climate resilience, and, most controversially, logging.
This episode looks at one patch of forest from three different perspectives: a conservationist who would like to see cutting halted in the WMNF, loggers who would like to see it ramped up, and the US Forest Service that has to somehow appease them both.
Featuring Zack Porter, Jeremy Turner, Charlie Niebling, Jasen Stock, Jim Innes, and Luke Sawyer.

Why we sing
Recently, our producer Justine Paradis noticed something. Humans really like to sing together in groups: birthday parties, sports games, church hymns, protest chants, singing along to Taylor Swift at the Eras concert... the list could get very long.
But... why? Did singing play a part in human evolution? Why does singing together make us feel so good?
Featuring Hannah Mayree, Ani Patel, Dor Shilton, and Arla Good.
