Unschooling with Kai

by Kai and Dan

After many car rides filled with episodes of the Stuff You Should Know podcast with the famous Chuck and Josh, Kai said, "Hey, we should make our own podcast!" Being fresh unschoolers ourselves, we decided to dive right in and start exploring topics of Kai's interest. Each episode is a different interest of Kai's. We figure out what we already know, research and answer our questions using the library, YouTube, museums, and the internet. Then we organize our findings and present them to you! Feel free to contact us at [email protected] with any feedback or episode suggestions.
