This book is a good benchmark book for young readers. It walks the reader through matter and what that is. I love how the author, Mason, explains matter because she has some great illustrations that show the reader that matter is everywhere. Mason also explains to the reader what solids, liquids, and gases are. Something that I really enjoyed about this book what that after each area of science, Mason includes a science experiment for the reader to try. This makes the book more hands-on and a great resource for students and teachers. I would use this book in my classroom as a support to different lessons on physical science. From a pedagogical stand-point, this book has some amazing vocabulary that allows the student to see and learn. ( )
