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.

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 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?

(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.
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!

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!
On October 26th, an FDA advisory panel will meet to discuss whether or not to recommend the Pfizer-BioNTech COVID-19 vaccine for kids ages 5 to 11. With potential approval coming soon, we’re answering questions from kids and parents about the vaccine, 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.

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. * > “Why can’t we drink medicine to keep us safe from the virus, instead of shots? - Eloise, 5, Texas 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.
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 https://www.champlainorchards.com/ in Shoreham, Vermont to learn more about apples. Our guides are 10-year-old Rupert Suhr, his father, Bill, and apple expert Ezekiel Goodband.

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.
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 https://seabed2030.org/, a global collaboration designed to map the sea floor, by 2030.

(CBC Kids) https://www.cbc.ca/kidscbc2/the-feed/what-lurks-in-the-depths-of-the-deepest-ocean * > “How deep is the deepest part of the ocean?” –Freya, 8, Wellington, New Zealand 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!
Kala wants to know why we say soccer in the United States, when the rest of the world calls the game "football."

"It's an interesting question because so many people around the world play the game of football," said David Saward, now-retired men's coach at Middlebury College. "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."

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.
