Author #173: Coppens cake and geology

Geology Is A Piece Of Cake by Katie Coppens.  Cleverly tying together geology with cake, Ms.Coppens, a middle-school English and science teacher, takes the reader on a journey linking science with science from geologic structures and processes to how they relate to different aspects of cake such as how eating a piece of cake is related to how animals cause weathering.  She uses cake to help explain Mohs scale of hardness.  The book is primarily about geology with some cake references included.  She's got a good balance-just enough cake references to whet the appetite and keep you going through the book without feeling like you're overwhelmed in sweetness.  Her approach also makes geology easier to understand and encourages the reader to learn more about science in general.
