Brains On! Science podcast for kids

Brains On! does something clever that most kids' science shows miss entirely: it puts an actual kid in the co-host chair every single episode. Molly Bloom leads the show alongside rotating child co-hosts, and the result is a dynamic where questions feel genuine rather than staged. Each 25-to-31-minute episode tackles a single question — how do apples grow, what's inside a jellyfish, how much does the sky weigh — and brings in real scientists to help find answers. The Mystery Sounds segment has become a fan favorite, where listeners try to identify strange audio clips before the reveal. There are also original songs baked into episodes, which sounds corny but actually helps cement concepts in a way kids remember. With nearly 400 episodes and a 4.5-star rating from over 13,000 reviews, the show has earned its reputation as one of the best educational podcasts for families. The production team includes Bridget Bodnar and Jed Kim alongside Molly, and they strike a balance between being genuinely informative and never talking down to their audience. Kids submit questions that drive the show, so topics stay fresh and unpredictable. It's the kind of podcast where a six-year-old and a ten-year-old can both get something out of the same episode, which is harder to pull off than it sounds.
