The Fact Fly’s One Big Question Podcast

Ever wonder why the ocean is salty—or how all that salt even got there? Join Lauren and the always-curious, always-chaotic Fact Fly as they dive into this big, scientific mystery in a fun, kid-friendly way! In this episode, young explorers learn about Earth’s water cycle, rock erosion, minerals, rivers, and the surprising journey salt takes before it ends up in the sea. We shrink down to molecule-size, splash into waves, zoom through rivers, explore undersea vents, and uncover the real science behind ocean salinity, evaporation, salt crystals, and Earth’s ancient oceans.

Packed with humor, vivid soundscapes, surprising facts, and easy-to-understand explanations, this episode helps kids (and grownups!) understand questions like:

How does salt get into the ocean?

Why aren’t lakes as salty as the sea?

Do underwater volcanoes make the ocean saltier?

What happens to salt when ocean water evaporates?

Perfect for curious minds, science lovers, ocean fans, and families who enjoy high-quality educational podcasts. Whether your child loves STEM, Earth science, marine biology, or just wants to know how the world works, this adventure makes big scientific ideas fun, silly, and unforgettable.
