I’m contemplating a program in Connecticut, possibly tapping into sources akin to Orion magazine.  To start off one needs a sense of wonder about nature above all.  Here is a link to “A Case for Wonder.” I have a variety of other books to suggest, and a particular fondness for one that is brief so readable by youths, The Hidden Heart of the Cosmos: Humanity and the New Story, by Brian Swimme of the Center for the Story of the Universe.
