Thanks for all this!
I have been listening to a history course this summer, in preparation for SOTW3 (history was never my strong suite) while DH has been listening to one on Greek philosophy. I don't drive much, and rarely anywhere that takes 30 minutes for an entire lecture, but I'll start a chemistry one as soon as I'm finished with history. I'll put it on during dinner prep in the kitchen!
I've preordered the 4th ed. of the Kingfisher Science Encyclopedia, and can't wait to give it to DS when it arrives in October. I'm looking into some chemistry board games, too. Thanks for the video/lecture/website ideas!
