Remember the whale from our tugboat episode? One curious Carpool Classroom listener had a question: What happened to it?

In this special follow-up episode, Mrs. Nelson investigates the story of the 67-foot fin whale that arrived at the Port of Tacoma after being struck by a ship. We'll follow the whale's journey to McNeil Island, learn how scientists figured out what happened, discover what a necropsy is, and find out what happens when a whale's body is left to decompose naturally.

Along the way, young scientists will think about an important question: How can we help keep whales safe when ships and whales share the same waters?

One curious question can lead to a whole new adventure.

If Earth is a giant ball floating in space... why don't the people on the bottom fall off?!

In this episode of Carpool Classroom, Mrs. Nelson and her Space Scientists investigate one of the most important forces in our universe: gravity! Kids will discover how Earth's mass creates gravity, why gravity pulls everything toward the center of our planet, and why "down" isn't actually the same direction everywhere on Earth.

Along the way, we'll bring back our basketball Earth, ask the mind-bending question “Which way is down?"

and add another important tool to our Space Scientist Toolkit. Buckle up, Space Scientists—it's time to find out what's keeping your feet firmly planted on Earth!

Blast off with Mrs. Nelson as Carpool Classroom begins an out-of-this-world adventure through our solar system!

In this episode, kids will zoom farther and farther away from home to discover their “space address." We'll start right where we are on Earth, then travel out to our solar system, the Milky Way galaxy, and beyond! Along the way, young scientists will learn just how enormous space really is—and where our tiny planet fits into it all.

Perfect for curious kids who have ever looked up at the night sky and wondered, “Where exactly are we in space?"

Buckle up, Space Scientists-our Solar System series starts now!

How can a little tugboat move a ship that's hundreds of times bigger than it is? In this episode of Carpool Classroom, Mrs. Nelson explores the surprisingly powerful world of tugboats! Young learners will discover what tugboats do, why huge ships need their help, and how these small-but-mighty boats push, pull, and guide vessels safely through busy harbors. Along the way, kids will build vocabulary, practice thinking like scientists and engineers, and discover why being small doesn't mean you can't do a BIG job!

Mrs. Nelson and Crew learn about the layers of the Earth and solve a mystery: could we stop the Earth from spinning?

Join Mrs. Nelson and Crew as we learn about the different habitats and nests of birds around the world!

Crew and Collins join for an episode on Capybaras!

What really happens after you flush the toilet? In this engaging (and slightly silly!) episode of Carpool Classroom, we follow the journey of wastewater as it travels through pipes, pump stations, and all the way to a treatment plant.

Learners will discover:

How waste moves through underground sewer systems

What happens inside a wastewater treatment plant

The important jobs that keep our water clean and safe

Then, we switch gears into writing! Students will learn how to:

Write a clear summary

Organize ideas in order

Use transition words like first, next, then, and finally

This episode combines real-world science with essential writing skills—helping kids understand both how systems work and how to explain them clearly.

Why do authors write? In this episode of Carpool Classroom, learners become reading detectives as they explore the three main types of writing: informative, opinion (persuasive), and narrative.

Through clear explanations and fun, interactive examples, listeners will learn how to:

Identify different types of writing

Recognize clues that reveal the author’s purpose

Decide whether a text is teaching, convincing, or telling a story

With guided practice and engaging challenges, this episode helps young readers build a strong foundation in understanding author’s purpose—a key skill for reading success.

Curious how a frog and a butterfly grow and change? In this episode of Carpool Classroom, learners explore the fascinating life cycles of both animals—from eggs to adulthood—while building important reading skills along the way.

First, we dive into the stages of a frog and a butterfly, learning key vocabulary like metamorphosis and noticing how each animal changes over time. Then, we shift into becoming thoughtful readers by learning how to compare and contrast using what we’ve learned.

Listeners will practice:

Identifying similarities and differences

Explaining their thinking clearly

Using text evidence to support their ideas

This episode blends science and reading in a fun, engaging way—perfect for curious kids and growing thinkers!
