I read this book to my children on account of Ambleside Online's recommendation. I really enjoyed it, and my children really enjoyed it. This Nature Reader covers such topics as blood, muscles, nerves, bones, the coverings of animals, how animals think, and how man is superior to animals. Each chapter concludes with an extensive list of questions about the chapter. Some of the explanations are a bit dated (for instance, the book claims that electricity is not involved in the brain sending messages to, or receiving messages from, the nerves).
On the whole I thought this book an excellent narrative book (not a modern textbook) about scientific topics for children. I would recommend it to those looking for a science book with literary quality for children. I would like to acquire the other books in the series and read them with my children.
Perhaps even more importantly, I would recommend Ambleside Online to any parent or educator.
