Mountain life: How's the air up there?
1 maart 2022 · 36 min
The ExPLORERR was built to go everywhere. That’s why this vehicle’s full name is: the Extremely Practical Land and Ocean Rover Exploring Remote Realms. And guess what? It has a recording studio built on-board! Good thing, because this episode was recorded while traveling up, up, up a mountain! Lees meer
We discover some wildlife that lives at great heights as well as a rhyming ice cream salesman. Our pal and atmospheric scientist, Dr. Deanna Hence checks in to answer a popular question: if hot air rises, why is it so cold in the mountains? BRRRR! We also hear from NASA’s Dr. Dalia Kirschbaum, who has mountains of information about how mountains form.
Of course, there’s a fun Mystery Sound for you’re ears to explore! And lastly, but not leastly, our two new books came out today. Head to our books page to find out more about Road Trip Earth and Earth Friend Forever.

Chilling out with snow
22 februari 2022 · 32 min
There are many different types of snow. From the fluffy to the slushy, this slippery frozen stuff comes in all different shapes and sizes. Lees meer
From a distance, snowflakes may all look the same, but they are not. In fact, there are lots of different shapes of snowflakes — not just those classic shapes you might try to replicate with paper cut-outs.
In this episode, Dr. Ken Libbrecht answers all of our snowflake questions: How are snowflakes made? Why are they different shapes? How is it that they’re all unique? And how does a scientist who lives in southern California study snow? And, he also lets us in on his brush with a couple Arendelle princesses.
Plus our pal Ruby Guthrie pays her local ski slope to visit a snow-making machine called “Kevin.” And of course, there’s a new Mystery Sound to warm your ears.
If you’re looking for some fun snowflake activities to do at home, Ken’s provided this great list — and you don’t need to live in a cold climate for all of them: http://www.snowcrystals.com/activities/activities.htmlThis episode was sponsored by:

Why do we like sugar so much?
8 februari 2022 · 29 min
Marshmallows, lollipops, gummi bears -- we want them all! But we’ve all heard that eating a lot of sugar isn’t that healthy for us. So what’s the deal? Why do we like sugar so much in the first place? We’ll find out why our bodies evolved to seek out sweet things, and how clever humans invented a way to make food even sweeter. And we’ll get to the bottom of a confectionary conundrum from our co-host Zoe: are sugar rushes a real thing?

Do we live in a multiverse?
1 februari 2022 · 40 min
Get ready to learn the science behind the multiverse! That’s the idea that our universe isn’t the only universe out there. What if there were other, different universes existing alongside our own? Ones with different laws of physics, different planets and stars… or maybe even different versions of us!
In this episode we explain a few different theories behind this popular idea. Plus, we’ll learn some quantum mechanics, hear about string theory and meet many different versions of Sanden.

What happens if you drop a feather in space?
23 november 2021 · 33 min
In space, will a feather stay still? Fall down? Float away? Turns out, the answer depends on where you are! But one thing affects your feather no matter what: gravity!

5 oktober 2021 · 40 min

What causes wildfires?
20 juli 2021 · 38 min
A fire can be super useful or cozy or even magical. But it can also be dangerous -- and in the case of wildfires, if they burn long and hot enough, they can destroy ecosystems and send lots of harmful smoke into the air.
In this episode, we're going to find out why wildfires are getting bigger and why wildfire season is lasting longer now. We'll learn how the tribes who've lived in what is now called Northern California managed the forests and kept fire in check for thousands of years, and how those practices are being used today.
We'll hear from a friendly house about how to stay safe from smoke inside and find out how firefighters work to contain fires once they've started.

Million Bazillion answers your questions about money
15 juli 2021 · 21 min
Today we’re sharing an episode with you from our friends at Million Bazillion, the podcast that answers the questions kids have about money. They help dollars make more sense and they’re back for a whole new season!
In today’s episode, hosts Jed and Bridget answer a question from two curious listeners who want to know why we pay taxes. In answering the question, they come across the legendary Robin Hood, known for his hatred of taxes. Back in his day, tax-collecting sheriffs forced people to pay money to a king, who decided how those taxes were spent. These days our tax system works a bit differently. We get to vote for people who’ll spend that money on things we care about — like schools and libraries, health care for elderly people, police, parks, sewers and so on. With the help of a rambling troubadour and a tax policy expert, Jed and Bridget teach Robin Hood that the way tax dollars are spent today reflects what we prioritize as a society. Plus, we’ll ask random kids some not-so-random questions.
Million Bazillion is a collaboration between Brains On and Marketplace. It’s hosted by Jed Kim and Bridget Bodnar.

The Hoax Hunters make an appearance plus the Moment of Um answers the question, "What is a solar flare?" Lees meer

Why do songs get stuck in our heads?
7 juli 2021 · 33 min
You know that feeling where you get a snippet of a song stuck in your head and it loops over and over? Those hard to shake songs are also known as earworms, and in this episode Molly has a particularly sticky one in her brain.
We'll find out why some songs are catchier than others and, most importantly, scientifically-proven ways to get rid of them.

Do dogs know they're dogs?
22 juni 2021 · 30 min
We treat dogs like they're part of the family. But do they know they are a different species, or do they think they're just short, four-legged people?
In this episode, canine cognition researcher Alexandra Horowitz helps us puzzle out this question. We’ll also find out what happens (or doesn’t) when a dog looks in the mirror. Dogs are always dozing, and we’ll check in to see if they are dreaming too. And, we take a quick trip around the world in the language of barks.

How far can a cloud travel?
8 juni 2021 · 31 min
We’ve all played the “what does that cloud look like” game. Maybe you saw a bunny… or an airplane… or a unicorn. What if that same cloud could also be seen by someone in a far off continent? That’s what a listener in Minnesota wondered. He wanted to know if the same cloud he saw in a park near his house could also be seen in Africa. Lees meer
We talk to Deanna Hence, one of our favorite weather experts, and she tells us about how clouds travel. We also dust off the Zoom Ray to learn about what is inside of a cloud. And have you ever noticed the similarities between cloud types, like cumulonimbus, and magic spells from Harry Potter? Well, we have, and we made a game out of it!
We also have a brand new Mystery Sound for your guessing pleasure and a Moment of Um that answers the question: Why do pugs have such scrunchy faces?

How do computers store so much info in such a tiny space?
25 mei 2021 · 39 min
If you translate “Hello! How are you?” to binary code, it looks like this: 01001000 01100101 01101100 01101100 01101111 00100001 00100000 01001000 01101111 01110111 00100000 01100001 01110010 01100101 00100000 01111001 01101111 01110101 00111111 Lees meer
This episode takes a look at how computers can do so much with such tiny parts. But computers weren't always small -- so we take a look at where computers came from. We visit Ada Lovelace, whose love of math and weaving paved the way for modern-day computers. And we hear about the material that let computers shrink from the size of a room to something that fits in our pockets. There’s also a visit from a yak and a ram, but you’re just going to have to listen to find out why.

Dino Edition: How do we know what dinosaurs looked like?
2 maart 2021 · 31 min
20 years ago, we pictured dinosaurs as green, scaly animals. But times have changed! Now, we know some dinosaurs had feathers. And who knows — maybe some even had stripes. Lees meer
This episode looks at how we figure out what color dinosaurs might’ve been. We talk to Jingmai O’Connor, who studies fossil reptiles, about finding color pigment in fossils. And paleoartist Emily Willoughby talks to a “museum” about how her dino-depictions have changed over the years.
Our co-host, Elyana, also brought us this important question: If dinosaurs evolved from birds and birds don’t fart, did dinosaurs fart? Wha-wha-what!?! Look no further than this episode for an extensive investigation.
Remember to keep your ears open for the brand new Mystery Sound. And break out your kilns, because today’s Moment of Um answers this question: How do you make clay for pottery?
There’s so much dino-tastic information that we decided to make a second dinosaur episode. So if you haven’t had enough (and who has?), make sure to check out next week’s show about what dinosaurs might have sounded like.

Meet Gitanjali Rao, Time Magazine's first-ever Kid of the Year
19 januari 2021 · 23 min
Today we have a special episode featuring an old friend of ours -- scientist and inventor Gitanjali Rao. Time Magazine recently named her the first-ever Kid of the Year!
We first met Gitanjali back in 2018, when she was the co-host for a series of episodes we did all about water. Back then, she was a 12 year old who had recently won 2017 Discovery Education 3M Young Scientist Challenge.
Now, she's a very busy 15 year-old who is an inventor, STEM advocate and author. Molly and Gitanjali chat about how kids can turn their ideas into reality, and why kids shouldn't be afraid to share their viewpoints and skills with the world -- we need them!
Gitanjali has also written a book, which you can check out here.
Also, you can hear Gitanjali judge a very science-y Smash Boom Debate: Helium vs Neon!
Check out the water series that Gitanjali co-hosted: Lees meerWhat’s in your water?
