In this listener-powered episode, we answer some of the curious, clever, and thoughtful questions you've sent us! Why do kids get sick more often in winter? What exactly is celiac disease? What happens if you never brush your teeth or go to the dentist? And why do we sometimes cry or yawn in strange places—like inside a car? With clear explanations and a warm, bedtime-friendly tone, we explore the science behind everyday mysteries in a way that's easy to understand and fun to learn. Perfect for curious kids (and their grownups) who love asking why?

Sleep Tight!,

In this episode, we're going to start to learn all about the amazing field of computer science. We'll talk about what computers really do, how we can talk to them using code, and how they follow step-by-step instructions called algorithms. We'll even explore a big question: can computers learn? And finally, we'll think about how you might learn computer science someday—and what you could do with those skills.

In this episode, we will learn about the water cycle—evaporation, condensation, precipitation, and collection. We will discover how water moves, changes form, and returns to us again and again. The rain that will fall today might once have been part of a glacier, floated in a cloud above a mountain, or even quenched the thirst of a dinosaur millions of years ago!

In this episode, we’ll discover why yawning isn’t just about being tired—it helps cool your brain and can even be contagious! We’ll explore the nature of time and why building a time machine isn’t as simple as it sounds. We’ll also uncover why eating salty foods makes us thirsty and how different countries developed their languages over time. Finally, we’ll look at why children need parents and how this is similar to animals in the wild, where young creatures learn essential survival skills from their families.
