But Why: A Podcast For Curious Kids

But Why is a show led by you, kids! You ask the questions and we find the answers. It’s a big interesting world out there. On But Why we tackle topics large and small, about nature, words, even the end of the world. Have a question? Send it to us! Adults, use your smartphone's memo function or an audio app to record your kid's question (get up nice and close so we can hear). Be sure to include your child's first name, age, and town. And then email the audio file to questions@butwhykids.org

But Why is now a book series! Are Llamas Ticklish? and Do Fish Breathe Underwater? are coming in June 2022. Learn more and pre-order here.

But Why has learning guides and coloring pages to complement our recent episodes. Our learning guides were designed to meet Common Core standards. Teachers, check out our list of learning guides by category.

Latest Episodes
  • The Washington Mystics of the WNBA join us in this episode to answer all of your questions about the sport of basketball and what it’s like to be a professional athlete. How many basketballs does the team have? Who invented basketball? Why do people think sports are just for boys? Do you get hated on for being a girl in professional sports? How do injuries impact professional careers? And do you have to be tall to play hoops?
  • For the past 50 years, visitors to the Smithsonian National Zoo in Washington, D.C. have been able to observe giant pandas. It’s one of the few places in the United States to see these black and white bears. For our latest episode we took a field trip to the zoo to visit the three pandas currently living there and answer panda questions with zookeeper Mariel Lally. We tackle: Why do animals live in the zoo? Why are pandas black and white? Do pandas hibernate? How can we save the pandas? And check out our social media pages for lots of pictures!
  • When there's mass violence in the news, especially when it involves children, it can be really hard to know how to speak to your kids about what is going on. In this special episode FOR ADULTS, we talk with a child psychologist about some recommended ways to approach these conversations. We first released this episode in 2016, and are heartbroken and angry that it remains so relevant.
  • What is climate change? What is causing climate change? How do you cool down the earth? How is climate change affecting the oceans? Kids are hearing about climate change and they have lots of questions. In this episode we explain the science of climate change and look at how humans will adapt to a rapidly warming planet. We speak with Dr. Claudia Benitez-Nelson, oceanographer at the University of South Carolina and Dr. Jola Ajibade, a geographer at Portland State University. This certainly isn’t a comprehensive look at the issue, but it’s a good way to start a conversation about this issue for families and teachers.
  • Why do flowers bloom? How do flowers grow? Why are flowers different colors? Why do people find flowers beautiful? How are seeds made? Why do plants grow from seeds? Why do we put seeds in the garden? We’re answering your questions about seeds and flowers with garden writer Charlie Nardozzi and Hannes Dempewolf from The Crop Trust. Find more answers to plant questions in two of our older episodes: How Do Big Plants Grow From Such Small Seeds? and Are Seeds Alive?
  • Why are some people right-handed and some are left-handed? And what’s up with some people being ambidextrous (equally good with both hands)? Why, in the past, did some people try to make left-handed people use their right hands? We talk with Chris McManus, professor and author of the book Right Hand, Left Hand: The Origins of Asymmetry in Brains, Bodies, Atoms, and Cultures. We’ll even find out how common left-handedness (or left-pawedness) is in other animals!
  • Why do pigs snort? And why do we call their snorts “oink” in English? We’re taking our exploration of animal noises in two directions today. First we’ll learn about why we use different words to describe animal noises, depending on what language we’re speaking. And then we’ll examine what animals are actually saying when they oink or tweet or moo! Our guests are Arika Okrent and bioacoustic researcher Elodie Briefer, of the University of Copenhagen. Other questions we tackle in this episode: Do cows make different amounts of “moos” to say different words? Why do ducks make loud noises? Why do roosters cockadoodle-do in the morning? PLUS, so many kids sent us animal noises in different languages and we’ll hear them all!
  • We’re bringing back an episode from the archives, all about the moon: Why does the moon change shape? How much does it weigh? What color is it? Why does the Earth only have one moon? Why does it have holes? Where does it go when we can't see it? Why do we sometimes see it in the daytime? And why does the moon look like it's following you when you're in the car? Answers to your moon questions with John O'Meara, chief scientist at the W.M. Keck Observatory.
  • The invasion of Ukraine has been the top story in the news for the last few weeks, and kids around the world are asking questions about what is happening and what it means for them. In this episode we ask Erin Hutchinson, Assistant Professor of Russian History at the University of Colorado Boulder, to help us understand the history behind this conflict. Adults: we don’t go into detail about what war looks like on the ground, but we acknowledge war is a scary topic. You may want to preview this episode ahead of time to make sure it's right for your kids.
  • Violet, 5, wants to know: what was life like before refrigerators? And Ellinor, 6, asks: how did they make ice in the old times? In this episode, we learn about the history of ice harvesting and the industry that built up around it, where ice cut from lakes in New England was shipped to as far away as India and the Caribbean. We hear more about this history from Gavin Weightman, author of The Frozen Water Trade. And we visit Rockywold-Deephaven Camps in New Hampshire, where ice is still harvested each winter from Squam Lake and used to keep old fashioned ice boxes at the camp cool all summer long.
