What would Earth be like if our oceans never existed? That’s what Charlie wants to know! We recruit Earth detective Lucia Perez-Diaz to help us track down clues hidden within our planet’s rocks. Our investigation takes us through the mysteries of how water got on Earth, the giant plates moving beneath our feet, and why our oceans are shaped the way they are. Lucia’s also an illustrator, and will draw us an Earth without oceans. What will it look like? Listen to find out. Lea

We tag along with scientists following a secret map on a mission under the cover of night, to find a buried treasure. It’s all part of one of the longest running, most legendary experiments in science history! We follow plant biologist David Lowry and his team on this secret scient

EDUCATION RESOURCES: NGSS Standards: LS Why do carved pumpkins rot faster than uncarved pumpkins? That’s what Ari, an 11 year old podcast host, wants to know. To find out what’s making good Jack O’Lanterns go bad, we turn to squash detective/ scientist Michael Mazourek. Together, we track down clues to crack the case - and find out how we make a Jack O’Lantern last forever. MEET MICHAEL MAZOUREK Michael Mazourek is a vegetable breeder at Cornell University. He specializes in

EDUCATIONAL RESOURCES: NGSS Standards: LS How long can a seed live? To find out, scientists follow a secret map on a mission under the cover of night, to find a buried treasure. It’s all part of one of the longest running, most legendary experiments in science history! We follow plant biologist David Lowry and his team on this secret scientist-spy-treasure hunt, which only happens once every 20 years. But things don’t go quite as planned. Find out what happens on this epic sc

EDUCATIONAL RESOURCES: NGSS Standards: LS Do trees fart? It’s a question that stumped scientists, and sends us on a journey to some serious science! Come with us as we ponder if trees are butts, whether farts are defined by gas or digestive systems, and why “even the smallest fart counts.” You’ll meet Mary Heskel, a plant biologist who wonders if she’s accidentally been studying tree farts, and Melinda Martinez, who studies climate change and happily calls herself a tree fart

Oscar and Mae Johnson were nine and twelve when they traveled to the Galapagos Islands with their scientist dad. The Galapagos are isolated tropical islands made famous by Charles Darwin, who came up with the theory of evolution based on his research

EDUCATION RESOURCES: NGSS Standards: LS 3-LS3-2, 4-LS1-1 Crosscutting Concepts: Cause and Effect, Systems and System Models Can plants feel pain? Not really, but they can sense a lot more than you might give them credit for! That's right, plants talk to each other. And we're just starting to understand them. Dr. Appel took this research one step further when she discovered "listening plants ." In the study, caterpillars were placed on Arabidopsis, a small flowering plant r
