What sounds do fish make? 🐟🎶 We know that cows say moo, and sheep say baa, but what do fish say? Come explore “Under the Sea” to discover the chorus of fish noises with help from fish ecologist Audrey Looby.  We’ll find out how fish can be sneaky, loud, and even “slimy, grumpy cuties” (Audrey’s words) who go boop boop - and what they can tell us about life underwater. 🌊

You can learn more about Audrey, and find a transcript of this episode on the blog on our website, sciencepodcastforkids.com.

Are ghosts real… or not? That’s what Lily wants to know. To find out, we talk to a real-life Ghostbuster and science historian Efram Sera-Shriar, who takes us on a journey back in time to when the world’s most famous scientists became ghost investigators: Sitting in on séances, inventing ghost-hunting devices, and exposing the tricks of “spirit photography.” Did you know, Thomas Edison made plans to create a phone to call ghosts? Learn all this and more when you join us on the trail of spooooky spirit science!

This is our final Mailbag episode before all-new stories of science discovery arrive on Friday, October 17. Lindsay and Marshall share behind-the-scenes updates on what’s coming up in Season 11 — plus a special challenge to guess the topics of our first three episodes!

Then, astrophysicist Dr. Hakeem Oluseyi (host of NOVA’s Particles of Thought and judge on Netflix’s Baking Impossible) joins us to tackle your big-universe questions:

• How does your body know you’re in a black hole?
  

• How do asteroids form?
  

• Why don’t we feel dizzy as Earth spins?
  

• And… what dessert would be best to eat in space?

Plus we read your reviews, share how to support Tumble, and send in your own guesses and stories. Next time, we kick off a brand-new season of science adventures!

Why are there so many axolotls in fishtanks, and so few in the wild? That’s what Maximiliano wants to know. You may have found axolotls in the lush caves of Minecraft, but in real life, they live in the lakes and canals of Xochimilco, near Mexico City. But the species is slowly disappearing from its native habitat. Axolotl veterinarian Horacio Mena takes us on a journey to Xochimilco to find out what scientists are doing to save these adorable amphibians.

This material is based upon work supported by the National Science Foundation under Grant No. 2415575.

This is a summer rebroadcast of an episode of Tumble from a few years ago.

How big is the universe? And how do we know? It's a question that puzzled astronomers for centuries. They had no way to measure distance in space - until Henrietta Leavitt showed them how. Henrietta Leavitt was a "computer" in the 19th century, before there were computers, and she made an incredible discovery that would help change the way people thought about the universe - forever. Modern-day astronomer Karen Masters helps us tell her remarkable story.

If you like this episode, you'll love our free audio course, "Cataloging the Universe" where you'll learn much more about how Henrietta Leavitt's discovery made a big difference in astronomy - plus, you'll become a skywatcher yourself! "Cataloging the Universe" is more than a podcast. It’s interactive! Each episode - or lesson - in the series contains activities to complete while you listen. Plus, you’ll get discussion questions, graphic organizers, and a star journal to keep your observations in. Check out the series and download all the resources at ⁠our website⁠!

Hear more from Karen Masters in the bonus interview episode available to Patrons, when you pledge just $1 a month or more on our ⁠Patreon⁠ to support the show!

We have free resources available on ⁠our blog⁠ to learn more about the episode.

Also... psssssst.... here's that top secret crossword puzzle!

Would you fly to the top of a volcano that’s about to erupt at any moment? Volcanologist Helena Buurman did, and survived to tell the tale! In 2008, Helena was monitoring Mount Redoubt in Alaska, when the ground beneath the volcano began to shake. What follows is a tale of volcanic adventure, involving earthquakes, helicopters, and a massive eruption!

Tumble is on our summer break right now, working on some exciting new projects. Stay tuned to hear them in our feed!

We invite you to invent your own volcano! Find resources to learn more about volcano warning signs and eruptions, on our website at www.sciencepodcastforkids.com
