I only own three and have only read three of the five books in the series. This is the one I don’t own but have read. It’s intended for the seventh grade. Asimov wrote the introduction. It consists of the following sections, with the ones written by Gallant marked with a (G). One difference between the Advanced Level books (for junior high school) and the Intermediate Level books (for elementary school upper grades) is that J. Myron Atkin is listed on the spine (but not the title page); Atkin was the general editor for the series.
The quote on the cover is “I love fools’ experiments. I am always making them…” by Charles Darwin.
This book represents an enormous advance over the earlier volumes, and it has nothing to do with the writing. The fact is that the book is much better illustrated and much better typeset, with a better visual distinction between the various variety of text section. It’s amazing what a difference that makes. It has a sense of being better organized, it’s easier to follow, and it makes the whole thing much more useful and realistic to use as a textbook. I was surprised how much I enjoyed it, and I would actually approve even decades later for this book to be a part of my children’s curriculum.
