I LOVE this podcast! This is a great way to learn new things, but not just hearing straight up facts! There is a STORY, and a LESSON on science! For this reason, I think it’s unique and interesting! For example, another podcast I love, Tumble, (recommend it), just talks to scientists and tells you the facts. On the other hand, Brains On! does both a story, while teaching you something related to science! So if you’re a fan of knowing the most, (I am), or loves science, or something like that, this is the podcast for you! I even sleep with this playing every night!

This show has been one of our go-to, absolute FAVORITE podcasts ever for years. However, lately there’s been a large influx of hosts with significant speech impediments. Inclusiveness is extremely important, and we applaud Brains On! for that, but when this is an audio only show, it’s incredibly difficult to understand what’s being discussed and taught (especially while listening in a vehicle). There has to be a better way to include these wonderful children AND allow for listeners to not intensely struggle to understand to the point of frustration and simply turning off the show.

This is my children’s (and mine) favorite podcast! Each episode is such a joy and my children always love to talk about each new topic. Thank you for this! It makes pickup and road trips enjoyable.

My family loves your podcast! My brothers and and I love to listen to your podcast when we get bored or just when we want to rest. It’s so relaxing to listen to, that it’s perfect the fall asleep to. But, then again I don’t want to fall asleep because I want to know the answer to the question! 😄 Keep up the great work guys, make more awesome episodes!
