Tumble Science Podcast for Kids

How big is the universe? And how do we know? It's a question that puzzled astronomers for centuries. They had no way to measure distance in space - until Henrietta Leavitt showed them how. Henrietta Leavitt was a "computer" in the 19th century, before there were computers, and she made an incredible discovery that would help change the way people thought about the universe - forever. Modern-day astronomer Karen Masters helps us tell her remarkable story.

If you like this episode, you'll love our free audio course, "Cataloging the Universe" where you'll learn much more about how Henrietta Leavitt's discovery made a big difference in astronomy - plus, you'll become a skywatcher yourself! "Cataloging the Universe" is more than a podcast. It’s interactive! Each episode - or lesson - in the series contains activities to complete while you listen. Plus, you’ll get discussion questions, graphic organizers, and a star journal to keep your observations in. Check out the series and download all the resources at our website!

Hear more from Karen Masters in the bonus interview episode available to Patrons, when you pledge just $1 a month or more on our Patreon to support the show!

We have free resources available on our blog to learn more about the episode.

Ever wondered how dinosaurs left their footprints behind millions of years ago? We embark on a prehistoric adventure with renowned paleontologist Paul Olsen! Discover the secrets behind dinosaur tracks and how these ancient prints can tell us incredible stories about the lives of dinosaurs. From the science of fossilization to what these footprints reveal about dinosaur behavior and habitats, Paul Olsen will guide us through the fascinating world of these mysteries left in stone - and share how he discovered thousands of dino tracks when he was just a kid.

Join us on a Dino Map Adventure at nepm.org/dinomap! We’ve created a free audio tour to explore the science and history of dinosaur tracks in the Pioneer Valley of Massachusetts. Lindsay and Marshall will guide you through the place where dinosaur footprints were first discovered - and put you on the path to becoming dino track explorers! Dinosaur Adventures in the Pioneer Valley are supported by The Bement School, The Center School, and HCS Headstart.

How do species evolve? Find out in the shocking conclusion of our Monkeyflower mystery series! Plant biologist David Lowry has been tracking down clues to solve the question of why plants look different - and the yellow monkeyflower is more than a suspect. Now, it’s time to take his detective skills up a notch, and use the science of DNA. A twisted discovery will flip the case - and lead to a new chapter in understanding how life evolves.

Why do plants grow in different places? How do they adapt to different environments? And what makes them different species? Those are the questions that drove biologist David Lowry to begin a 20 year study of a shape-shifting plant called the yellow monkeyflower. It begins with a road trip, and ends up questioning everything you think you know about the definition of species. Get ready for a wild, plant-fueled ride into science!
