Tumble Science Podcast for Kids Tumble Media

This is a summer encore episode of one of our favorite episodes from Season 4 of Tumble!
Do you love fossils, adventure, and spending time in small spaces? If so, you could become an underground astronaut! Marina Elliot, Becca Peixotto, and Kenni Molopyane found this unusual job description through a Facebook ad, and landed deep inside a cave that few people can access. The team of archeologists talked to Tumble in the middle of excavating Homo Naledi, one of the biggest recent discoveries on the human family tree. Find out how they squeeze through a 7 inch gap on their daily commute, and how their work could change the way we understand early human history.

How do scientists find out if an asteroid might hit our planet? And what do they do if it’s on a collision course with Earth? We’ll meet a planetary defender - an astronomer who uses radar telescopes to defend our planet from space rocks! Edgard Rivera Valentín grew up in Puerto Rico, next to Arecibo, the world’s most powerful radar telescope. Hear the story of how Edgard became a scientist superhero, and the supervillain asteroids they’re up against. 

A bonus interview episode with Edgard is available to Patreon members who pledge at the $1 level or higher at patreon.com/tumblepodcast.

How did cicadas evolve to go underground for so long? Why do cicadas spend so much of their lives underground? That’s what listeners Gus and Zachary want to know. This spring, up to a TRILLION cicadas will emerge across 16 states in the U.S., in an event that hasn’t happened since 1803. Cicada scientist Chris Simon helps us dig into the surprising science of cicadas - and figure out how they’re changing on this science podcast for kids.
