This text is an introduction to the fundamental behaviour of matter and energy in living and nonliving systems. It introduces basic concepts and key ideas while providing opportunities for students to learn reasoning skills and a new way of thinking about their environment.
This book was geared towards elementary school teachers who are going to teach students about science. What I liked most about this book was that it explained a lot of information in a way that was easy to understand (like nuclear reactions). My only criticism of this book is that the chapter on reproduction talked about orgasms. I highly doubt I'll have to talk about orgasms to elementary aged students once I start teaching full time.
