Tumble Science Podcast for Kids

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!

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!

Check out their awesome science boxes at https://melscience.com/sBHH/ Make sure to use the offer code "TUMBLE" at checkout for 60% off your order.  Here is Dr. Bubble’s Giant Bubble Recipe, courtesy of Emory University: Ingredients 1 liter of water (about 2 pints) 50 milliliters of Dawn Professional Detergent, which is available online (a little over 3 tablespoons) 2-3 grams of guar powder (or guar gum), a food thickener sold in some grocery stores or available online (about 1/2 heaping teaspoon) 50 milliliters of rubbing alcohol (a little more than 3 tablespoons) 2 grams of baking powder (about 1/2 teaspoon) Directions Mix the guar powder with the alcohol and stir until there are no clumps. Combine the alcohol/guar slurry with the water and mix gently for 10 minutes. Let it sit for a bit so the guar hydrates. Then mix again. The water should thicken slightly, like thin soup or unset gelatin. Add the baking powder and stir. Add the Dawn Professional Detergent and stir gently, to avoid causing the mixture to foam. Dip a giant bubble wand with a fibrous string into the mixture until it is fully immersed and slowly pull the string out. Wave the wand slowly or blow on it and enjoy the physics of giant soap bubbles! Results may vary based on humidity.
