Special Episode: How do you talk to kids about violence in the news?
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.
Dr. Robin Gurwitch is a child psychologist at the Duke University Medical Center, and she has served on numerous commissions and committees about children and trauma, including the National Advisory Committee on Children and Disasters.
Though this episode is for adults, we know children sometimes listen to episodes without adults around, so the information in this episode is intended to be non-traumatizing for children to hear. (Transcript)

Why do pigs oink?
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 linguist and author 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!

How did people keep food cold in olden times?
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.

How are images chosen for coins?
The U.S. Mint is producing a new series of quarters featuring American women. The first one, featuring poet Maya Angelou, has just been released. We're learning about coins are made and how images are chosen for money around the world. The US has a law preventing any living person from appearing on its money. Kenya has a new rule preventing any individual people on their money at all. Meanwhile, many countries with kings or queens have those leaders on their money while they’re still in power. Questions we tackle in this episode: How are coins made and how do they get their logos? How are presidents chosen for coins? Why does Lincoln have his shoulder in the picture while other presidents don’t? Why are coins different sizes? What are coins made of? We learn more from Rodney Gillis of the American Numismatic Association and Leigh Gordon of the Royal Australian Mint.

What would you invent? Ideas from kids
We asked our listeners: if you could invent anything what would it be? And we got so many fantastic ideas from kids all over the world: a solar cooler, a chimney that changes carbon dioxide to oxygen, a slide that gives you an ice cream cone at the bottom, and more. Some kids would like to invent robots that do their chores, flying cars, teleporting devices to take them back in time, and even a bully behavior zapper.
This episode is all about creativity! But how do you take a great idea and turn it into reality? We’ll get advice from teenage brothers Ayaan and Mika’il Naqvi, who invented, patented and now sell Ornament Anchor after Ayaan came up with the idea in fourth grade.

Do skyscrapers scrape the sky?
Why is the Burj Khalifa so tall? That’s what 5-year-old Simon wants to know. The Burj Khalifa is the tallest building in the world and it’s located in Dubai. 6-year-old Isabel, who lives in Dubai, visited the tower and gives us the bird’s eye view in this episode! Plus, Janny Gédéon, architecture educator and founder of ArchForKids answers lots more questions about tall buildings: How are tall buildings built? How do they stay up? Why are so many buildings squares or rectangles? How do they make buildings that are taller than cranes?
Architecture workshops and online learning: ArchForKids
Try making the tallest tower you possibly can, just using paper. (Newspaper works great if you have some newsprint lying around. But printer paper or construction paper is fine, too.) You should focus on making it strong and stable. Strong means that it can hold something. Stable means that if it’s pushed to the side it can stay upright. You can use cardboard for the base, but otherwise, see how you can do with just paper. Need a hint? Janny says to think about the ways you’d stay stable when playing sports.

How do squirrels climb trees?
Squirrels are everywhere. Three hundred or so species of these often adorable rodents live on every continent except Antarctica. No matter where you live, city or country you’re bound to have squirrels nearby. How much do you know about our bushy-tailed neighbors? How fast do squirrels and chipmunks run? Why do squirrels have big bushy tails? Do squirrels get sick? Why do they like nuts better than berries? How do squirrels eat acorns? How do squirrels sleep? Are squirrels nocturnal? Answers to your squirrel questions with Ben Dantzer, scientist at University of Michigan. Plus some observational activities you can do to learn more about squirrel behavior!
Submit your squirrel observations to iNaturalist
Squirrels have long nails and they have five digits (fingers or toes) on their paws just like us.
And squirrels are expert climbers. “Some tree, or arboreal, squirrels are really well adapted to climb up trees whereas ground squirrels also have nails or claws, but they use them primarily for digging and not for climbing,” explains Ben Dantzer. “Tree squirrels have this especially long middle digit that helps them climb up and down trees.”
So an extra long middle finger and they can do something else that humans can’t. “The most helpful thing they can do is when they climb down a tree, squirrels can turn their back feet around when they’re climbing down head first. They turn their rear feet entirely around so they can use those claws to hang down from a tree and walk down easily.”
What? Tree squirrels can turn their feet all the way around so they’re backwards when the squirrel is climbing down a tree?! Time to go outside and see if you can observe that in the wild!

Why is it a shot? Kids’ questions about COVID vaccines
The FDA recently gave emergency use authorization to the Pfizer-BioNTech vaccine for kids age 5 to 11. With all the news and conversation about this development, kids are curious to know more about the Covid vaccine--and vaccines in general! So in this episode we answer questions from kids and parents, including: Why does it have to be a shot? How do vaccines work? How does a vaccine trial work? Should an 11.5yo get the shot as soon as it’s available or wait until age 12 to get the larger dose?
We speak with Sofia and Nico Chavez and their parents. The kids took part in the vaccine trial at Stanford University. We’re also joined by Dr. Jenna Bollyky, an investigator in the Stanford trial site, and Dr. Mark Levine, Vermont’s Health Commissioner.
“In general, vaccines are a way to train your immune system without having to get sick,’ explains Dr. Bollyky
Your immune system is how your body works to fight off sickness from things like viruses.
Most vaccines use a small protein from the virus you want to fight, or from a similar virus – and they put that little protein in your body in a very small and weakened or changed amount to help your body learn how to fight the real invader. But giving the vaccine as a drink or a pill wouldn’t work, because of your stomach acid!
“Whenever we want to give a protein or something that your body turns into a protein, the acid in the stomach does a really good job of breaking down that protein. So it’s really hard to get a vaccine that comes as a pill,” Bollyky says.
In order to get that vaccine into your muscle, where it needs to go, a doctor or a nurse uses a thin needle. They do have to poke you, but that doesn’t mean they like it. “If we could give it as a pill we would,” Dr. Bollyky promises! While that poke might hurt, sometimes the anticipation of the shot is worse than the real thing.
The reason your arm sometimes aches after getting a shot is that the immune cells are coming to be educated. “The cells around where the medication was delivered, they’re doing their job, they’re taking in the information they need and are starting to train your immune system,” Dr. Bollyky assures us. “So that immune response is exactly what you want to teach your body to fight the infection should you encounter the real virus later.”
It’s normal to feel a little tired or run down after some vaccines, including the COVID vaccine. But if you feel very ill, you should contact a doctor or health care provider.

How Do Apples Grow?
Why do apples have stems? Why do fruits start out as flowers? How did the first apple grow when no one was there to plant its seed? Why can you make a seedless grape and not a seedless apple? Why are apples so juicy? How is apple juice made? Why are apples hard and pears soft? In this episode we take a field trip to Champlain Orchards in Shoreham, Vermont to learn more about apples. Our guides are 10-year-old Rupert Suhr, his father, Bill, and apple expert Ezekiel Goodband.
Actually ALL fruits start as flowers (but not all flowers turn into fruit). Growing fruit is a way that some plants reproduce. Fruit is the nice ripe container that holds the seeds, which humans or animals will eat and then spread around (often through their poop), allowing new plants to grow.
But that process begins with a flower. The outer part of the flower often has beautiful colors and shapes and smells—and that’s all part of the way the plant tries to attract a bee or other pollinator:
“The flower has an ovary at the base of the petals. The petals are enticing a bee to come with the pollen from another blossom that it’s visited and there’s some nectar that the bee can collect and while the bee is doing that it’s shedding some pollen,” explains Ezekiel Goodband. “That pollen completes the information that the apple needs to start growing. So the flower is to attract the bee.”
That ovary at the base of the flower will start to grow and that will become the apple that you eat. If you look at the bottom of an apple—the opposite end of where the stem is attached to the tree—you can actually see where the flower used to be. It even kind of looks a little bit like a tiny flower.

How Deep Is The Ocean?
We’re exploring a part of the world that not much is known about—in fact, you could be one of the people who help us understand and learn more about this very important, and very large, part of our earth.
The land underneath the ocean is as varied and interesting as the terrain up on dry land—with mountains and canyons, plains and forests. (That’s right, forests! There are kelp forests where the kelp is as much as 150 feet tall!) In this episode, what’s known--and unknown--about the bottom of the ocean. How deep IS the deepest part of the ocean? And how was the Mariana Trench formed? We get answers from Jamie McMichael-Phillips and Vicki Ferrini of Seabed 2030, a global collaboration designed to map the sea floor, by 2030.
The deepest part of the ocean is the Challenger Deep, 11,034 meters in the Mariana Trench. It’s about seven miles deep! How did the trench get so deep?
The same processes that formed canyons and mountains on dry land also formed the depths of the ocean and the islands that peek above the water.
In the case of the Mariana Trench, it was formed by the process of subduction—when one tectonic plate slides under another. A tectonic plate is a gigantic piece of the earth’s crust and the next layer below that, called the upper mantle. These massive slabs of rock are constantly moving, but usually very slowly, so a lot of changes to the earth’s structure take place over a long time. But sometimes something like an earthquake can speed that process up.
A trench is formed when one plate slides or melts beneath another one.
The Mariana Trench is the deepest trench in the world—farther below sea level than Mount Everest, is tall!

Why Do Americans Use The Word ‘Soccer?’
Kala wants to know why we say soccer in the United States, when the rest of the world calls the game "football." In this episode we hear from people who make their living in the game: professional players, coaches and commentators.
"What happened with the words soccer and football goes back to the 1800s when the game was developed. There were two groups of people in Britain who got together to set the rules of two different games, one that was known as rugby football, and another that was known as association football. From those two first words: 'rugby' and 'association,' came two very separate games. Rugby was abbreviated to the word 'rugger.' And out of the word 'association' came 'soccer.' That's the root of where the two differences came."
So although these days you probably won't hear many Brits calling the sport "soccer," the word actually originated there. Americans brought the nickname to the US, and as the sport became popular, soccer stuck.
"When you look around the world," says Coach Saward, "there are all sorts of different forms of football: American football, Australian rules football, Gaelic football, rugby football and association football. I think for the clarity of everyone over here when we say the word football, we think of people running around with helmets and pads on; so soccer is a very clear distinction."

Who Invented Money?
In this episode of But Why we visit a credit union to learn what money is all about. And Felix Salmon, Anna Szymanski and Jordan Weissman from Slate Money answer questions about why money plays such a big role in modern society. How was money invented? Why can't everything be free? How do you earn money? How was the penny invented? Why are dimes so small?
Related Episodes: What Is The Biggest Number?
There's no first person we can point to who invented money. The idea of money has evolved as human society got more complicated. In the early days of humankind, people mostly bartered. Bartering is essentially trading.
But over time people realized they needed to have a system for dealing with things when there wasn't an easy trade. If you have something I want but I don't want anything you're offering because I really need something else, how do we work it out? That's where the earliest forms of money emerged. First they were things like shells or rocks. Then pieces of clay with symbols or faces pressed into them. These things don't have much value by themselves, but if everyone agrees that they're going to use them as a symbol of value, you can trade them and start a system of payment.
Eventually these objects became more formalized, turning into coins and paper dollar bills, like the ones we use today. These days there's another method of buying and selling: the credit or debit card.

Why Do We Wear Clothes?
Have you ever been threading one leg through a pair of pants in the morning and wondered…why do we wear pants anyway? Or wondered why pockets in clothing designed for girls are sometimes smaller than the pockets in clothing designed for boys? In this episode we’ll tackle your questions about clothes with fashion historian and writer Amber Butchart.
Many people think we started to wear clothes for practical reasons of warmth and protection.
“We don’t have fur like other animals, so when modern humans started moving into colder parts of the world, we needed to protect ourselves somehow if it’s cold and snowy. This is one answer, that we wear clothes for protection,” said Amber Butchart. Butchart is a dress historian, author and broadcaster. She studies how the clothes we wear are connected to where we live and what kind of culture we grow up in, and what time period we’re growing up and living in.
Butchart says, while the protection theory explains why we have to wear something—to cover our skin from the elements, there are a lot of other answers that help explain the style of clothes we wear, or don’t wear. These have to do with culture and society, and ideas about modesty as well. In this case modesty means what’s considered proper, broadly accepted as not being too wild or “out there.” A lot of how we dress comes down to what is considered appropriate in our current culture.
“The idea is that these cultural codes built up across millennia and centuries and centuries, ideas that parts of our body should be covered up,” Butchart explained. “We have these social ideas to do with what parts of the body should and shouldn’t be on display, but we also have that combined with this need, especially in colder parts of the world, for protection from the elements.”
But when it comes to fashion, what you wear communicates something about you to the outside world, and clothing has gone through many changes throughout history. Listen to the episode to learn more!

What's the Cleverest Thing A Hippo Can Do?
What is the cleverest thing hippos can do? This week we’re answering seven quirky questions about animals! Why do elephants like peanuts? Why do cows put their tongues up their noses? Has anyone ever ridden a tiger? How do woodpeckers cling to trees? Why is some bird poop black and some is white? Why do people make animals like sharks and bears sound way scarier than they are? Answers from Keenan Stears of the University of California, Santa Barbara, Christine Scales of Billings Farm & Museum; shark researcher Kady Lyons and the Bird Diva Bridget Butler.
“The first thing that comes to mind that highlights the intelligence of hippos,” he told us, “is the ability to identify hippo friends from hippo enemies by the smell of their dung.” Dung is another word for poop.
“Dominant male hippos use dung middens to mark their territories. A dung midden is a place where an animal repeatedly goes to drop their dung. The dung middens act as a way that hippos can keep track of the other hippos in the area. So when moving through the environment, hippos can sniff out areas where their hippo friends live, versus areas where their hippo enemies live and they can do all of this just by smelling the dung in middens.”
Bet you didn’t think the cleverest thing hippos can do would involve poop! And just in case it wasn’t totally clear, a midden is basically a waste pile. So a dung midden is kind of like a toilet or an outhouse. It’s where the hippos go repeatedly to poop. But, as Stears told us, it also serves another purpose. While humans can’t tell their poop from someone else’s, other animals can sniff out individuals this way, and use dung or urine—pee—to mark their territories.
Hippos aren’t the only animals to use dung middens this way, by the way. Rhinoceroses do this too! Other animals, like dogs, cats, rabbits and monkeys also sniff feces and urine as a way to learn about their fellow species, but they don’t always leave their “messages” in the same place.

Why Are Fireworks Bright?
What are fireworks made of, why are they bright and loud, and how do people make them? And, why do Americans celebrate the 4th of July with fireworks? We learn about pyrotechnics with licensed fireworks professional John Steinberg. And David Chavez, an explosives expert at Los Alamos National Laboratory tells us how changes to the materials used in fireworks can make them better for the environment and unleash new, more vibrant colors in the night sky. We also address firework safety and how to impress your friends by knowing what kinds of metals are in the fireworks you’re watching or the sparklers you’re playing with.
NOTE: We know not all kids (or adults) enjoy the noise of fireworks. We do play the sound of fireworks at the very beginning and very end of the episode. And John Steinberg offers some advice to people who dislike fireworks in the middle of the episode.
Steinberg told But Why that the brightness is the main purpose of fireworks.
“You’re painting the in sky with light. It has to be bright enough to create the color and the effect you want to in the sky. Second, fireworks are explosive. You can’t be right up in front of it like a painting in an art gallery. You have to be some distance away, so the fireworks have to be bright enough for you to appreciate it,” he said.
Fireworks are created by burning materials that shine brightly when burned. Those fires are very hot! “The types of things we burn in fireworks burn very brightly, and they’re chosen for those properties,” Steinberg said.
Fireworks are created by a combustion in the sky – a combustion is something that burns.
“You need a fuel and you need something to burn that fuel,” Chavez said. “An example of a fuel would be gasoline or wood in a fireplace. In fireworks, the fuels are the chemicals that we use to make the firework itself. The oxidizer is another chemical. When those two things burn, they burn very hot. And those high temperatures excite the coloring agents that we have in fireworks.” The coloring agents are metals.
“Anytime you see red, that’s strontium. If you see a pinkish-purple, that’s potassium. Yellow is from sodium. Orange comes from calcium. The green is from barium, but now you can use boron. Blue is from copper. And these can be mixed to make other colors.
“You need a really hot fire to be able to excite these atoms, to make them give off their color. But when they are that hot, it makes the colors come out really bright.”
Chavez and other scientists have found ways to change the fuel source of fireworks to create less soot. Those changes also allowed them to replace barium, which can get into water sources, with boron, a greener way to create those green fireworks.

Who Invented Noodles?
This week, we're revisiting one of our favorite older episodes from the past. We’re going to learn a little bit about the history of noodles--and how to make them!
And we also get an exciting hand-pulled noodle demonstration from Tony Wu, who was the executive chef at M.Y. China, a restaurant in San Francisco’s Chinatown, when we originally recorded this audio in 2019. Wu can hand-pull 16,000 strands of noodles from one lump of dough in just two minutes...while blindfolded! Narrating this noodle-pulling exhibition is celebrity chef Martin Yan, who owned the restaurant. (M.Y. China closed during the pandemic.)
The first written references to noodles or pasta can be found in Chinese texts dating back about 3200 years. Author Jen Lin-Liu says it's likely that pasta developed in China and in the Middle East within a couple hundred years ago. But what likely didn't happen was the often repeated idea that Italian explorer and trader Marco Polo "discovered" noodles during his two decades traveling in east Asia and then introduced them to Italians upon his return.
"Probably what happened," Lin-Liu told But Why, "was they were invented in China and they were also invented somewhere in the Middle East a little bit later, probably a few hundred years later. And there were two parallel cultures of noodles that developed separately.
"And then," Lin-Liu continues, "because of the interactions between cultures later on, they started merging. So they were probably eating noodles in Italy and China at separate times and they didn't have much to do with each other at the beginning."
As for how noodles are made, the ingredients are pretty basic: just flour and water. Sometimes eggs are used in place of water in Italian pasta. They can then be turned into noodles or pressed into different shapes. Sometimes they're filled with meat and cheese or other ingredients and turned into dumplings or tortellini or other filled-pasta shapes.
Making pasta takes skill, both to get the consistency right and to make the perfect shapes. At Martin Yan's San Francisco restaurant M.Y. China, executive chef Tony Wu puts on a weekly show for diners, displaying his ability to hand-pull 16,000 strands of noodles from one lump of dough in under two minutes. Yan calles him a "human pasta machine," and we get to experience the excitement in this episode.

Are Seeds Alive?
Are seeds alive? What are they made of? Here in Vermont it's planting time, and we've been getting a lot of questions about seeds from kids around the world. In this episode we'll explore the importance of preserving seed diversity with Hannes Dempewolf of the Global Crop Diversity Trust. Crop Trust manages a repository of seeds from around the world at the Global Seed Vault in Svalbard, Norway, above the Arctic Circle.
Plus, ethnobotanist and Abenaki scholar Fred Wiseman shares a little bit about a project called Seeds of Renewal, which aims to find seeds traditionally grown by Abenaki people in our region and return them to cultivation.
More Plant Episodes:
The Svalbard Global Seed Vault contains an enormous wealth of seeds from around the world. Unlike other seed banks, the vault is designed not to be used unless there are no other options in other seed banks. Seed banks are places where seeds are stored for future use in case of a disaster or crop failure, and are sometimes given out to help establish new populations of heritage or rare plants and crops. Seed banks also promote genetic diversity by keeping many varieties of seeds from many different plant species.
Yes, seeds are very much alive! At least the seeds that we use to grow food are alive. Seeds can die if they're not properly cared for, if they get too hot or cold or wet. But under the right conditions, they're just dormant.
"It means they're sleeping basically," Dempewolf says. "Seeds are dormant and they need to be activated to grow. They need light to grow, along with humidity and warmth, that's the conditions that allow seeds to grow."
"Different species of plants have very different kinds of seeds and different types of seeds also need very different conditions to grow. Some grow with very, very little humidity with very little wetness, and some need a lot. Some need to be submerged in you know under water for a while until they can grow. Some need to be frozen first before they can grow. Some seeds are made that they have to first be eaten by an animal and then pooped out again, so they can grow. Some grow with very, very little wetness, and some need to be submerged underwater for a while until they can grow. Some need to be frozen first before they can grow. Seeds are amazingly complex."

How Are Words Added To The Dictionary?
Our guest this week is a lexicographer. That's someone who studies words and, in this case, edits dictionaries. Emily Brewster is a senior editor at Merriam-Webster and host of the podcast Word Matters.
Emily answers a question from 8-year-old Emma in Kentucky, who wants to know how words are added to the dictionary. But before we can answer that, we'll tackle 7-year-old Julia's question, "How are new words created?" Join us for an episode about how words are created, when they've reached a critical level of use to get their own dictionary entry, and when words are removed from the dictionary. Get ready for some word nerdery!
More Word Episodes:
Lexicographers like Emily Brewster read and listen a lot and pay attention to the new words that people are using. They collect these examples and determine how many instances there are of the word and what different kinds of sources are using the word.

How Do You Whistle?
How do people whistle? How does whistling make a sound? Why does your tongue change a whistle higher or lower? Can you get a trophy for whistling? Can people with laryngitis whistle? Get ready, we learn all about whistling with musician and champion whistler Emily Eagen and musician Yuki Takeda. And who whistles our theme song? We'll hear from musician Luke Reynolds, and a kid whistling chorus from our listeners!
Emily says the first thing you should do is lick your lips or use lip balm. "If your lips are dry when the air passes it doesn't feel good," she says. Then you'll make your lips kind of into a pucker, circle your lips tightly.
Next, stick your tongue touching your bottom teeth. Then you make kind of a yuh, yuh, yuh sound. "But instead of saying the words, make it with a little stream of air. You want to let air pass over the top of your tongue and out your lips. You're making a tiny little instrument by curling your tongue."
"I like to think about between your nose and your lips, that's a little body part called a philtrum. I like to pretend that my whistle is coming out of that. That helps me make the sound have a little focal point," she says.
Emily says it helps to make little sounds when you practice. "Pretend your sipping tea with that little tiny space there. You don't want to push too much. If you blow too much air it won't work. You have to be really gentle."
Once you find your first whistle, it's all about practice and playing around to see what sounds you can make.
"If you move your tongue forward, the notes go up, and if you move your tongue down, the notes go down," she says. If you can make a variety of notes, then you can start putting them together to make music!

Ethics: Is It OK To Break A Rule?
Is it OK to do something that you were told not to do and then never tell anybody? In this episode we tackle that thorny question from 10-year-old Finn from Seattle. We'll also wrestle with the question, "Why do people make really bad choices and want other people's lives to be harder?"
We're tackling some ethical dilemmas in this episode and we're letting kids give the answers! We also get a response from ABC Radio's Short & Curly, a podcast devoted to ethics for kids.
Here's how some of our young listeners answer the question about whether it's ever okay to break a rule and lying about it:
"No, because it usually just means you get in trouble." - Juniper
"I think so. If you're protecting somebody or keeping a surprise." - Camille
"It depends who told you. Like if your parents told you, then you shouldn't do it. Or if you do it, you should tell them you did it. But if it's like a mean person you met on the street it's ok. And it depends what it is. Because if it's a bad question, you shouldn't do it either way if it's a bad thing. If it's a good deed you should do it. And if you did that, why wouldn't you tell anyone?" -Sylvie
"No, not really. If you don't tell anyone about it. It's mostly the doing it and then not telling anybody about it. Mostly what isn't the good thing about it. It's a little bit worse, if you don't tell someone you might get a feeling where you feel kind of embarrassed. And you don't tell anybody and it just sticks with you the rest of your life." - Piper

Why Do We Compete?
Have you ever felt competitive with a friend or a sibling? Competition comes up in a lot of different ways in life. Maybe you're running a race with a friend and you want to beat them! Maybe you're trying to play a song without making a mistake and you're competing against yourself.
Sometimes competition feels good and fun. It can make you want to do better, and make a game more enjoyable. But not always. Sometimes competition feels bad. Like it's too much pressure, or takes away from the fun of being with your friends. Some people really don't like competition at all.
3-year-old Kai from Tokyo, Japan asks: "Why do we need to compete with other people, especially friends, for example on a sports day or at gym class?"
In this episode we discuss competition with anthropologist Niko Besnier. And we'll hear from 12-year-old Harini Logan, a competitive speller from San Antonio, Texas, and 10-year-old Del Guilmette, an athlete from Monkton, Vermont.
We put Kai's question to Niko Besnier, anthropologist at the University of Amsterdam. One of his books is called The Anthropology of Sport, written with Susan Brownell and Thomas F. Carter. He says there are two reasons that people take part in competitions:
"One is that sports are fun. It's fun to play with your friends and classmates, to run, jump, play ball. We've all experienced this rush of pleasure and fun doing these things. But the other aspect that's contradictory to the fun part is that it enables us to measure our strength, our speed, our physical ability against those of other people. It's the competition part of sport, and competition can become extremely serious. Frequently, the fun part of sport gets lost."
Besnier says when competition gets out of hand it can lead to hurt feelings, and on a larger scale, competition can lead to things like war and inequality.
But with the right attitude, competition, especially when we compete against ourselves, can help us get better at sports and academics.
That's how it is for Harini Logan. She's a competitive speller who has made it to the Scripps National Spelling Bee twice!
"Competition teaches you a lot, whether it's the preparation leading up to that competition or the outcome," Logan says. "It can teach you a lot about not only your abilities, but also new things that can change the way you look at life. When you're preparing for a competition you can learn how to work hard, and how not to give up on something. And during the competition you learn teamwork. That's one thing you learn in spelling bees, because you want to be with your community, your friends. One thing to learn if you win: sportsmanship! You don't gloat about it, you still appreciate yourself but you don't overdo it so others don't feel bad. And if you don't win it doesn't matter. [You just say:] I'm going to try harder next time."
Competing also helps us get better. That's how 10-year-old Del Guilmette views it. He likes to play against tough teams when he plays sports, because that's how you get better.
"The best players at the game, whatever sport it is, they didn't get better because they played teams that they knew they were going to beat. They played those teams that were better than them. They got better and they practiced!"
Listen to the full episode to hear more about how these mature young competitors think about the value of competition.

Why Are Mammoths Extinct?
In the ice age, megafauna roamed North America: mammoths, saber-toothed cats, even giant land sloths! What happened to them? In this episode we answer questions about the ice age: What was it? Did birds live during that time period? How about giraffes? Did people live with woolly mammoths? Why did mammoths go extinct? We'll answer your questions with Ross MacPhee, senior curator at the American Museum of Natural History and author of End of Megafauna: The Fate of the World's Hugest, Fiercest, and Strangest Animals. And we'll hear from Nathaniel Kitchel, a Dartmouth researcher who used carbon dating to discover the age of a mammoth rib. Plus, John Moody, of the Winter Center for Indigenous Traditions in Norwich, Vermont, on how mammoths appear in the oral history of the Abenaki people.
In the Pleistocene era, which lasted from 120,000 years ago to 15,000 years ago, ice covered the landscape in much of the northern hemisphere. Ice covered all of Canada down into the Northern United States and all of northern Europe. And there were smaller ice sheets in Russia. How did this happen? Scientists think it was a buildup of ice over time.
"The theory is that the winter never ended," explained Ross MacPhee. "You would have snowfalls in the winter and it never really got warm enough to get rid of it completely. The next year that would be built on, built on and built on. And the thing about snow is that it kind of makes its own weather. If you have snow it gets very cold! And that preserves the snow pack for a very long time."
The weight of that snow would compact into ice, eventually covering parts of the world in great sheets of ice. It might help to think of the process as a little bit like what happens when you have a favorite sledding hill: the snow is light and fluffy when you start, but if you sled down it enough times (and walk up the hill, too), eventually the paths get icy from the footsteps and sleds continually packing the snow down.
It wasn't just ice sheets that were a feature of the ice age. All of that water caught up in the ice made sea level drop 300 feet lower than it is now. That exposed lots of land that is now covered in water, including a land bridge connecting Alaska and Russia!
This land bridge allowed a number of species to move into North America from Asia, like bison. And some North American animals went into Asia, like camels and horses! Bear species traveled in both directions. Humans also used the land bridge to migrate into North America, though scientists think some early humans probably used boats too.
Mammoths also migrated over that land bridge! They originated in Asia and came into North America. But there were other species of megafauna that roam the landscape as well, like giant condors, saber toothed cats and even giant sloths.
These species went extinct at the same time as mammoths, as the ice age was ending. Listen to the episode to learn more about the theories of why so many large animals went extinct around the same time.

What’s Your Idea To Clean Up The Great Pacific Garbage Patch?
In 2019, we answered a question about the Great Pacific Garbage Patch, a huge mass of plastic and other trash swirling around in the Pacific Ocean. Mary James heard that episode and was so inspired, she created a device to help clean up the plastic in the ocean. In this episode of But Why, we learn about her invention, the mermicorn!
Listen back to Why Is There A Big Patch Of Garbage In the Pacific Ocean?
Kids: we'd like to know what you think could be done about all the garbage in the ocean. Download our learning guide above to draw a picture or describe an invention you would make to help clean it all up.
Mary James sent her picture of the mermicorn to the Little Inventors competition, for Canadian children. See Mary's entry here. Her invention has been chosen from among hundreds of other submissions to be turned into a prototype, a model of what the real thing might look like. There are Little Inventors competitions in the UK as well, and lots of countries and organizations sponsor design challenges for kids. See if you can find one where you live!

What Are Robots Doing On Mars?
On Thursday, February 18th, a robot called a rover is expected to land on the surface of Mars, and begin collecting information scientists hope will help us learn if life ever existed on that planet! We answer your Mars questions with Mitch Schulte, NASA program scientist for the Mars 2020 mission.
NASA has a number of ways that you can watch the landing live on February 18th at 11:15 a.m. PST / 2:15 p.m. EST / 19:15 UTC.
The rover is called Perseverance, which means not giving up, continuing to work toward a difficult goal even when challenges are placed in your way.
And it is quite a challenge just to get to Mars! The rover was launched on a rocket from Cape Canaveral in Florida more than 6 months ago, by NASA, the U.S. Space Agency. And it has been traveling through space ever since, on a path to Mars. And now, people all over the world are eager to watch it land on Mars and get to work.
And it’s not just Perseverance that is going to land on Mars. There’s also a helicopter, called Ingenuity, which means cleverness, creativeness and resourcefulness all rolled into one. Ingenuity, the helicopter, is basically a drone—there’s no one inside driving it around, just as there are no people onboard the rover. But ingenuity is the first helicopter to ever test-fly on another planet!

Cool Beans: How Chocolate And Coffee Get Made
How is chocolate made? Why can't we eat chocolate all the time? Why is chocolate dangerous for dogs? Why do adults like coffee? In this episode, we tour Taza Chocolate in Somerville, Massachusetts to learn how chocolate goes from bean to bar. Then we visit a coffee roaster in Maine to learn about this parent-fuel that so many kids find gross! And we'll learn a little about Valentine’s Day.
"Chocolate actually comes from cocoa beans--which is no bean at all--they are seeds of the cacao trees," says Ayala Ben-Chaim of Taza Chocolate. Taza is a "bean-to-bar" chocolate maker. That means starting with raw cocoa beans and going all the way through the process to turn those beans into a chocolate bar you can buy in a store. (Some chocolatiers get chocolate that's already mostly made and they just add stuff to it and shape it.)
The tree that those cocoa beans come from is called the Theobroma cacao tree, which grows in warm tropical parts of the world--within 20 degrees of the equator. Taza Chocolate sources (buys) cocoa beans from farmers in the Dominican Republic, Haiti, Belize and Bolivia.
It takes about five years from when it's planted for a cacao tree to produce cocoa pods. "Cocoa pods are a little bit funny to look at. They look like a gourd growing off of the tree, or like a lumpy tiny American football. The cocoa pods grow off of the branches of the tree like apples, but they also grow right off of the trunk of the tree," Ben-Chaim explains.
"The next step in the process is fermentation. Fermentation is so important in chocolate making. And this is one of the things that is so surprising about chocolate making.
After the beans ferment, they spend a week drying in the sun on wooden planks. At this point they look like almonds. Next, they are packaged and shipped to wherever they'll be made into chocolate.
The first thing the chocolate maker will do is roast the beans at 200 degrees for about an hour, which gives them a nice toasted flavor.
"We also start to separate the thin outer shell that surrounds the inner part of the cocoa bean. Our next step is to separate that shell from the inner part of the bean, called the nib. We do this by winnowing the cocoa beans, using a machine," says Ben-Chaim.
"At Taza Chocolates we use a traditional Mexican milling style using a molino - or mill - to grind the cocoa beans down," Ben-Chaim says, demonstrating. "Over time, those cocoa nibs will be turned into a cocoa liquor, which is smooth and chocolaty. Imagine a chocolate waterfall. It looks beautiful, it smells chocolaty and delicious and yet it is not very tasty because we're missing a really important ingredient, and that is sugar."
Sugar is added to the chocolate liquor, then the sweetened chocolate is ground again, and other ingredients are sometimes added, like spices or coffee or fruit.
At this point some chocolate makers will conche the chocolate, which blends and mixes the chocolate at a high temperature over many hours, which makes it smooth and creamy. Taza doesn’t conche their chocolate. The next step is tempering. Tempering the chocolate makes it glossy and brittle. Then the chocolate is poured into molds and cooled. Then it's wrapped up and ready to take home.
Also in this episode: we visit 44 North Coffee to learn more about the mysterious beverage that so many adults like to drink--coffee!

Why Are Cactuses Spiky?
What makes a cactus a cactus? And what are you supposed to call a group of these plants--cacti, cactuses, or cactus?! We'll find out in today's episode, as we learn more about the cactus family with Kimberlie McCue of the Desert Botanical Garden in Phoenix, Arizona. She'll answer kid questions about why cactuses are spiky and how they got those spikes, as well as why teddy bear cactuses aren't actually cuddly!
Those prickly spines that are so characteristic of the cactus family are actually modified leaves! Cactuses don't have the kind of leaves like a maple or oak tree. But they might have had leaves that were at least a little more like that way way back in the past. Over time, those leaves evolved into the spiky spines we see on cactuses today because they help the plants survive in hot, dry environments.
"They can be a defense mechanism to discourage herbivores - animals that eat plants - from eating the cactus. But, also, spines create shade!" explains Kimberlie McCue.
"Early in the morning, there will be fog that comes off the water. Those spines provide a place for the water to condense, form little droplets of water that run down the spine, to the body of the plant, down to the ground and to the roots."

What's A Screaming Hairy Armadillo? How Animals Get Their Names
Why are whale sharks called whale sharks? Why are guinea pigs called pigs if they're not pigs? Why are eagles called bald eagles if they're not bald? You also ask us lots of questions about why and how animals got their names. So today we're going to introduce you to the concept of taxonomy, or how animals are categorized, and we'll also talk about the difference between scientific and common names. We'll learn about the reasoning behind the names of daddy long legs, killer whales, fox snakes, German shepherds and more! Our guests are Steve and Matt Murrie, authors of The Screaming Hairy Armadillo, and 76 Other Animals With Weird Wild Names.
There are some animals whose names don't really seem accurate-like daddy long legs...which certainly aren't all daddies! Or bald eagles that very clearly have plenty of feathers on their heads. Or guinea pigs, which aren't actually pigs!

Hopes And Dreams For 2021 From Kids Around The World
As the new year dawns, what are you hopeful for in 2021?
Even though the change of the calendar year is mostly symbolic, New Year's Day is often a time for looking back on the year that just passed and setting goals for the year ahead. We asked you to share your hopes and dreams for 2021, from the end of the COVID-19 pandemic to your own personal goals. In this episode, more than 100 kids from around the world offer New Year's resolutions.
We'll also hear from Johns Hopkins University epidemiologist Jennifer Nuzzo, climate activist Bill McKibben and Young Peoples Poet Laureate Naomi Shihab Nye.
Here are just a few of the hopes and dreams you sent us:
"My environmental wish for 2021 is that we can stop so much pollution. My personal wish is to learn Urdu and to convince my brother to get a cat or dog!" - Maya, Toronto, Ontario
"My wish for 2021 is that the coronavirus will stop and the vaccine will come out and we can do things we haven't done this year and we can have our birthday together this year!" -Zain
"I want to learn how to ride my bike by myself. - Adelaide, 6, California
"What I want to happen for the new year is that I want people to start being responsible and no coronavirus. I want people to stop polluting. I want people to wear more masks. I want people to be kind to animals." - Jedi, 8, Ohio
My new year’s resolution is for sloths to take over the world and for people to use less plastic. - Sloan, 7, Wisconsin

Why Do Things Seem Scary In The Dark?
Lots of people are afraid of the dark, including many kids who have shared that fear with us. In today's episode we explore the fear of the dark with Daniel Handler, better known as Lemony Snicket, the author of the Series of Unfortunate Events books, and a picture book for young kids called The Dark.
Then we go on a night hike with Vermont Fish and Wildlife biologist Steve Parren, to talk about ways to embrace the darkness. We practice our night vision by not using flashlights and we think about how our other senses can help us navigate. Steve also answers questions about how animals see in the dark and why it sometimes look like animals' eyes are glowing back at us in the darkness.

Why Aren’t Babies Just Little Adults?
Why are babies small and grownups big? Why are babies so helpless, instead of little versions of adults? Do babies know they're babies? How do babies grow? How do babies learn to talk?
Kids have been sending us lots of questions about babies! This week we’re learning more about the development of the human brain with Celeste Kidd, professor of psychology and primary investigator at the Kidd Lab at the University of California Berkeley.
It seems like a really bad idea, right? Human babies rely on adult humans for everything, while babies of some species never meet their parents and are able to take care of themselves as soon as their born! Why is that?
While researchers aren’t sure on this one, Celeste Kidd says there are a lot of theories.
“Because we are very intelligent, we need bigger brains to account for all the things we can do that other animals can’t do. If you have a big brain and you’re born via live birth – meaning you aren’t born from an egg – then there’s an upper limit on how big your head can be when you go through the birth canal,” she explains.
In other words, we need those big brains to do all the things humans do, but a human head with a fully developed brain can’t fit through the birth canal.
“The bigger your head needs to be ultimately, the more immature you need to be born,” Celeste says. So we have to develop and grow outside of the womb. We’re born with some of our brain power, but our brains keep growing long after we’re born, well into our 20s. And there are some advantages to that long period of childhood.
“If you require dependence on your parents for a really long time, which humans do, that creates a lot of opportunity for you to learn a lot of stuff about your culture and the other people that you’re being raised with. We have a lot of knowledge that is unique to us as a species, and that’s unique to us as social groups,” Celeste says.
The long childhood allows for a lot of cultural transmission – learning about tools, language, manners and arts. Some of these exist in other species, but the human systems are a lot more elaborate and take more time to learn!

Why Are We Still Talking About The Election?
A few weeks ago we talked about why kids can't vote and we also answered some questions about the U.S. Presidential Election. It's been two weeks since the November 3rd election, but we're still getting questions about it! We get answers from NPR political reporter Ayesha Rascoe.
Here are some of the questions we're tackling in this episode: What would happen if someone counted the votes wrong? Why is President Donald Trump going to court and why are people saying Joe Biden might not be president? What is the Electoral College and why do we still have it; why haven’t we changed to a popular vote? How does the president talk to the people without being on the news?
Helping us answer these questions is political reporter Ayesha Rascoe, who covers the White House for NPR. Adults, you might want to check out the NPR Politics Podcast, a daily podcast that frequently features Rascoe's reporting and expertise.

Why Do Whales Sing?
In our most recent episode, we answered questions about really big animals: whales!
We covered a lot when it comes to these huge aquatic mammals but there was one big topic we didn't get to: and that's how whales communicate. We'll learn more about the sounds whales make: singing, whistles, and echolocation clicks with Amy Van Cise, a biologist at NOAA Northwest Fisheries Science Center in Seattle, Washington.

Why Are Whales So Big?

Why Can't Kids Vote?
In the United States, where But Why is based, we have a big election coming up. Election Day is officially on November 3rd. But more Americans than usual are voting in advance this year, sometimes in person at their town hall or city office. And sometimes by mailing in their ballot-that's the piece of paper where they mark down who they want to vote for. People in lots of states are voting for their governors, who help run their states, or their Congresspeople, who work in Washington to help run the country.
But the position that's getting the most attention is the election for who will be president for the next four years. We learn about voting and elections with Erin Geiger Smith, reporter and author of Thank You For Voting and Thank You For Voting Young Readers' Edition. Also: how does the government work? Why haven't we had girl presidents before? Why are Democrats called Democrats? Why are Republicans called Republicans?

Why do some cultures eat cows and others don't? Why do some cultures not have pets at all? And is it okay to breed animals like dogs that have significant health problems even though we love them? Herzog is the author of Some We Love, Some We Hate, Some We Eat: Why It's So Hard to Think Straight About Animals.
