[EX Q]: A Great book for the Early Childhood Classroom . This book helps you look at the big picture from beginning to end. Nature should exist in the classroom all year around. I love the open ended growing activities and setting up a growing center. I'm in the process of doing this in my classroom and the children love it. Check out their other books on structures and water too!
[EX A]: POS

[EX Q]: Excellent introduction to the field for physicists . Perhaps the best feature of this book is that it aims to convey the theory of Lie algebras and Lie groups to physicists. In doing so, the author is careful to give a very simplistic approach so that one not familiar with  the subject can understand it. Not to say that the book is elementary,  since it builds rapidly into the far more interesting aspects of Lie  Groups. A very good read
[EX A]: POS

[EX Q]: Waste of money . It's really a book for amateurs. Most of the tips you can find out yourselves by a little logical thinking
