1. A Brief History of Time- Stephen Hawking
Even though it celebrated it's 10th anniversary about 15 years ago, this piece of literature is a must read for science teachers. Hawking writes this for the layman (under 200 pages), taking complicated mathematical astrophysics and simplifies so my mom can understand it. Hell, he only uses one number in the whole book (the speed of light). I have my students in my Astronomy II class read this as supplemental material for particle physics, Einstein's Theories of Relativity, and Black Holes. Much of this book is still applicable with new physics, but you may want to look up some new physics after chapter 8.
