Our Alexa is in our kitchen, so I post a hardcopy list on our cabinet door. You can download the Word doc or pdf of my old list, but know it has not been updated lately. You can also make your own document, of course.

BrainsOn is the best for children. All others you really need to screen, as you are the best judge of what topics you want your children to hear.

Having said that, our favorites have included
— 365 Days of Astronomy (on Alexa, “Alexa, play 365 Days of Astronomy on TuneIn”)
— Planetary Radio
— Science Friday

Entire articles are out there. Check out this child-oriented list or this one, a more general list, or this one for space-related podcasts.

Enable the Anypod skill, and ask Alexa to play podcasts through it:

“Alexa, ask Anypod to play BrainsOn… Alexa, fast forward five minutes.”

Last time I checked, Alexa’s native podcast player did not include rewind or forward.

For Alexa, I enable the Anypod skill. Then, I can ask Anypod to play episode 300, the earliest episode, etc. Anypod will keep going for the podcast, playing the next (or previous episode) for you. You can Google Anypod commands.

For other ways to play podcasts, I use podcast players on my phone (FM Player) and PC (Grover). Those usually allow for more control, including adding episodes from different podcasts to one playlist.
