This book does a wonderful job in breaking down their science experiments into seasons; Fall, Winter, Spring and Summer. The first few pages of the book are dedicated to using science in your classroom, including using journals. Each activity is well layed out, and easy to follow. They list the materials needed, the aim of the activity, a warm-up, the activity, things to remember, observations, books that tie into the activity, and also some spin-off projects. This book could also be used by younger classes. To gain five stars, I would have liked to had more involved projects. I think sometimes, we under-estimate the learning capabilities of our kids.
