This book talks about where we get our energy, the role the sun plays in that, and the different cycles and sources of where all of our different types of energy comes from. I like this book because the book is written from the perspective of the sun and addresses the reader directly. I also think it is a good book because it has has great illustrations that are a good visual reference to visualize the material. This book would best be used for older elementary and even early middle school when discussing energy and fossil fuels. This book has a lot of information and would even be good to break down into a mini unit on energy and fossil fuels. ( )
