Tumble Science Podcast for Kids

Do trees think? That’s what our listener Alden wants to know. He has an idea that scientists might study mushroom roots to find out if trees are sending messages. Is that true? And if so, what do trees have to say?!We travel deep into the forest with a young soil scientist named Natalia Mondi from the Mother Tree Project, to find out how and why trees communicate through the ecosystem. Along the way, we’ll discover what trees are asking for, how their “forest buds” help them out, and how Natalia is using this knowledge to restore a forest in Canada, guided by the Kwiakah Nation.

What is dark matter? Why do scientists think it exists? How are they searching for it, and why are they doing it in an underground lab?! Join us on the search for dark matter with Alvaro Chavarria, a physicist running a dark matter detector underneath a mountain in the French Alps. We’ll take you inside the lab to visit the detector, and find out why everything we think we know about dark matter… could be wrong. For more, visit our website!

Who invented the peanut butter and jelly sandwich? And how did it become one of the most famous lunches in America? In this episode, a question from listener Leila sends us on a trip through history to find out how peanut butter, jelly, and sliced bread came together to make the classic PB&J. Along the way, we learn about the first written recipe for the sandwich in 1901, how peanut butter went from a fancy food to a lunchbox staple, and why sliced bread changed everything. To help answer Leila’s question, we turned to our buddy Mick Sullivan, host of the history podcast The Past and the Curious. Mick loved the question so much that he made a whole episode about it—and today we’re sharing it with you.

Why do humans usually have five fingers on each hand? And what if one day, we could grow a new finger if we lost one? In this episode, a question from six-year-old listener Ayla sends us on a journey from tiny developing embryos to one of the most amazing animals on Earth: the axolotl. We talk with Dr. Jessica Whited, a Harvard-based biologist who studies how axolotls regrow their limbs - and why humans can’t do the same… for now! Along the way, we discover how our hands develop before we’re born, why evolution settled on five fingers, and axolotls might show us the way to regrow our own limbs. Plus: why axolotls have to live in separate tanks (hint: they’re a little too snack-happy).
