I loved it. It was $9.98 in store, so I would grab it while you can if you are interested. There's a few instances where the information is slightly out of date (obviously it doesn't cover the evidence for water on Mars that was just released in September, and there was one or two other places where we updated it as we went), but that was honestly a great way for us to talk about how science works and grows and changes. This to me is as important as the actual information in the book. Carl Sagan said in The Demon-Haunted World: Science As A Candle In the Dark:
If we teach only the findings and products of science--no matter how useful and even inspiring they may be--without communicating its critical method, how can the average person possibly distinguish science from pseudoscience?
In that respect, the differences in what the book said versus what we now know gave us an opportunity to talk about how science works, how it changes as we learn new things, and how it corrects itself as new information comes to light.
I also heard about the Tiny Thinkers book series that's being launched with the help of David Smalley who hosts Dogma Debate. So far, they've planned three books: Charlie and the Tortoise (about Charles Darwin), Carl Goes To The Library (about Carl Sagan), Richie Doodles (about Richard Feynmann). You can check out the Go Fund Me here, and I for one am looking forward to adding these books to our home collection also.
I also can't wait to add A Children's Illustrated History of Presidential Assassination to our collection. This book by Bryan L. Young is a guide to the history of attempted and successful assassinations to kids--and it sounds fantastic. I'll definitely talk about it some more after we get it and read it. My eight year old is ridiculously psyched by the prospect.
Bonus: Some of the illustrations were done by Bryan's daughter, Scout, who's like eight or nine herself. If you'd like to hear an interview with the author, check out the Stuff You Missed in History Podcast that brought this to my attention!
