The Tale of The Hungry Koala [ENCORE]

Tumble returns with all new episodes starting January 22! We’ll have stories about fossils, telescopes, and baby falcons getting into big trouble.

How does a koala eat eucalyptus leaves? Eucalyptus is toxic to most animals, but they’re a koala’s only food. In this episode, we look past the cuddliness to discover how koalas manage to chow down on the Australian tree species. Biologist Michaela Blyton shares the story of how she convinced some extremely picky koalas to try new foods in the midst of a conservation crisis. Spoiler alert: It involves starting a koala hotel, and inventing a pill with an unusual ingredient.

9: Our Favorite Holiday Tradition (with The Secret Life of Plants ENCORE)

A log that poops presents? Find out about Lindsay and Marshall’s favorite holiday tradition, Tió de Nadal! Followed by one of Tumble’s favorite-ever episode, The Secret Life of Plants.

We’ll be back with brand new episodes in January. Thank you for listening to Tumble this year! Happy Holidays and see you in 2021!

8: The Coronavirus Vaccine Race

How did scientists develop coronavirus vaccines in record time? New York Times science reporter Carl Zimmer is our guide to the coronavirus vaccine race – from the starting line, to the point when several teams are racing to the finish line. Find out how science gave the competitors a turbo boost that could save hundreds of millions of lives.

The information in this episode is accurate as of its release on December  11, 2020. Looking for the latest vaccine information? Check out the links to the CDC, WHO, and Johns Hopkins University on the blog on our website, sciencepodcastforkids.com.

7: The Bacteria Cookbook

Bacteria are among the simplest forms of life on Earth. Each cell is identical to the one next to it, sharing the same DNA. So why do they all act so differently? Turns out, there’s a “cookbook” inside each teeny tiny bacteria cell, and every single bacteria has different ideas about the recipes it wants to make. Mary Dunlop is a biological engineer who’s a creative cook both in the kitchen and the lab – and she’s cooking up her own experiment of science discovery.

Watch Mary’s “cell movie” on the blog post on our website, sciencepodcastforkids.com. It’s really cool to see!

You can learn more about synthetic biology in our interview with Mary, available for Patrons who pledge at the $1/level or higher, on patreon.com/tumblepodcast.

This episode is supported by the National Science Foundation under award number MCB 2032357.

6: What’s Inside of an Atom?

What are protons, neutrons, and electrons made out of? That’s what listener Xander wants to know. Physics expert Aatish Bhatia takes us on a journey into the atom, and explains how scientists discover things that are too small to see. You’ll find out how Albert Einstein helped prove the existence of atoms, and why physicists smash particles like piñatas in massive tunnels.

You can learn more about how particle colliders work in our interview with Aatish, available for Patrons who pledge at the $1/level or higher, on patreon.com/tumblepodcast.

We have free resources available on the blog post on our website, sciencepodcastforkids.com.

4: The Science of Candy Land

Happy Halloween! We’re headed to Candy Land, a sugary laboratory where mathematicians found a mysterious candy dagger appear – over and over again. So gather up your candy box, and let’s discover out why mathematicians are studying candy to understand the real-life landscapes around us. Mathematician Leif Ristroph shares how he stumbled into making sweet experiments. 

Want to learn more about the reason behind Leif’s experiments? Listen to our bonus interview episode, available for Patrons at the $1/level a month or higher. Pledge now at Patreon.com/tumblepodcast!

Visit our website to see photos and videos of the candy daggers, and find out what a stone forest looks like. Plus, follow Leif’s special recipe for “research-grade candy.” Check it out on the blog at sciencepodcastforkids.com!

3: The Snot and the Whale

How do whales use their blowholes to breathe, and what keeps them from filling up with water? There’s no better way to find out than getting up close and personal with whales! That’s what marine mammal biologist Justine Hudson did when she collected whale snot from belugas. Snot or “blow” is the watery cloud that sprays up when whales exhale. Justine shares her incredible snotty adventure in the Arctic, and tells us how blowholes work.

Want to watch beluga whales chasing a boat of scientists trying to collect their snot? We have a video from Justine herself, on the blog on our website! Plus, more educational resources about studying whales. Visit sciencepodcastforkids.com.

Scientists have a few other surprising ways to study whales. Find out more in our bonus interview episode with Justine, available to Patreon subscribers for just $1 or more a month. Pledge today on patreon.com/tumblepodcast. During October 2020, pledges at $10/month or more get a special PuppetGram with our awesome puppet friends!

2: The Case of the Sleeping Trees (Interactive Episode)

Why do some trees go dormant? You’ll discover the answer for yourself in this interactive episode, with the help of tree scientist Nalini Nadkarni! Nalini has loved trees since she was little, and dreamed of inventing a special tree microphone to ask them questions. But she found the scientific process was a way to get answers, no special equipment needed. Nalini will guide you through making observations, asking questions, and discovering why trees shut down for the winter. 

Special resources for this episode are available on the blog for this episode, at sciencepodcastforkids.com.

Do you wonder how trees know WHEN to go dormant? We answer this question on a special mini episode, available to Tumble Patrons who pledge just $1/month or higher. Go to patreon.com/tumblepodcast to support the show and get access to all our audio extras.

1: The Poop Collector

If someone asked you to collect your poop every day for a year, would you say yes? That’s what microbiologist Lawrence David did, after watching a movie about a man who said yes to everything. Accepting the challenge led to a year of very stinky international adventures, turning Lawrence into the James Bond of poo. And, he loved every minute of it. Join us for the incredible story of a secretive project about the human microbiome.

This is the first episode of Season 6, and we’re so glad to be back! We’ve got so many great science stories to share with you.

Want to learn more about Lawrence and why we are what we eat? Watch curated videos, listen to related podcast episodes, and discover the cutting edge science on a blog for this episode at sciencepodcastforkids.com.

Find out what Lawrence eats, and if he’s good at dealing with bad smells, in a special bonus episode for Patreon supporters. The answers will definitely surprise you. Just go to patreon.com/tumblepodcast and pledge just a dollar a month to hear it, and all our other scientist interviews.

Season 6 Starts September 18! + How To Keep Kids Engaged in Online Learning (For Parents!)

All new episodes of Tumble are starting on Friday, September 18! We have a preview of what’s coming (for kids!) and helpful advice from a teacher (for parents!).

Our co-host Marshall has been a teacher for almost 17 years. He’s putting together a podcast mini-series for parents on Patreon called, “Tumble Teaching Tips.” In this first episode, he answers a BIG question: “How do I keep my kid(s) engaged in online learning?” You’ll learn about two research-based ideas to keep your child motivated – both in school, and in life. We hope this gives Tumble families some tools to navigate this unusual school year.

Marshall will be doing more “Tumble Teaching Tips” on our special Patreon feed. If you’d like to sign up to listen, and receive all our other great rewards, pledge $1 or more a month at patreon.com/tumblepodcast
