I'm really enjoying using this text - great book, amazing and interesting information and the presentation of the material is very user friendly. I'm using this text for my K grade children and they love the information and the expirements. While the book is definately geared for older (maybe 1st/2nd grade or higher) I'm not disappointed that I bought it or that I'm presenting it to the children. We'll hit this book again in the future. It's a great library addition as well.
I am very excited about this acquisition have reviewed the book and is quite well structured without being tedious, I like the content in general and how the pose, as well as his experiments. I know it will be a wonderful voyage will share with my son. And the best IS CHRISTIAN!!!!
Excellent textbook with wonderful supplementary materials. Serious content and thoughtful lesson structure. The companion Notebooking Journal is worth it, as it has self-contained cut 'n paste exercises, etc., as well.
