Are cats evil? Are they hatching a plot to take over the world? Or are they just misunderstood? Scientist and cat expert Mikel Maria Delgado will tell us how the domestication of cats and dogs changed the way we think of our pets today, and she’ll explain how scientists of all ages can study cat preferences (or purr-fur-ences). Plus, she’ll share some tips on cat do’s and don’ts, so we can learn how to be better friends to our kitty companions.

For more information about Mikel and more on cat science, visit our website at sciencepodcastforkids.com, where we'll have resources, videos, and more.

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!

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.

What do you call a scientist who studies poop? A poopologist! We’re exploring the stinky science of “poopology” at the zoo, to discover what poop can tell us about animal behavior! Poopologist Laurel Wescott, at the Oregon Zoo, will take us on a journey to find how chemicals found in animal poop can help zoo animals stay healthy. Plus, she’ll clue us in on the “cutest” and most surprising poops, and so much more!

“Do dogs think and feel the way we do?” We all know dogs can’t talk. That’s why scientists have to come up with creative ways of asking our canine companions what’s going on in their minds. We’ll find out why dog cognition scientist Zachary Silver put on a play for dogs - which inspired us to create Tumble’s very first dog radio theater production! Just call us “The Tumble Dog Players.” It will all make sense by the end of the episode.
