Wonderopolis

Wonderopolis is a great informal learning site.  Each day, a new topic or question is discussed.  Questions like “What are hors d’oeuvres?” , “Why are there revolving doors?”, “Why can’t all medicines be swallowed?”.  Each topic has a link to find out more, usually with a video, always with an explanation.  This would be a great way to start the day and get those little brains warmed up.  For all ages and completely free.
