My only problem with this book was that it was too complex for my daughter to understand on her own. I like my daughter to work on all her projects independently with only minimal guidance from me. There were concepts in this book that were difficult for her to understand, and I had to guide her through some of the ideas and explanations.
On a brighter side, she got an A on her project, and her teacher chose her project to display in the classroom as one of the teacher's favorite projects.

This book has been a tremendous help to me. I think that it can help others do fantastic science projects as well. It was easy to find what I was looking for, and when I found it, it was even easier to understand without scientific phraseology that tends be confusing.

Projects and activities to teach concepts, terminology, and (according to the author, Janice VanCleave) laboratory methods. This book and the others in the series each describe 101 experiments. For biology they are classified under plants, animals, and humans. Each is presented in a two-page spread with an illustration on the right. The order is logical. By working through the book doing some experiments and reading about the others, one would form significant concepts. An explanation is given for each activity. Growing carrots from carrot tops demonstrates that a plant can grow if it has portions of base, stem, and root, and if it receives food and water.
The explanations are oversimplified in some cases (for "finger monocle" for example). Younger students need simpler explanations, but I believe the scientific principles could be stated more accurately. Also, some of the illustrations could be improved, but basically the book is good.
For a total science program I would recommend a textbook or a number of broad topic books. Individual experiments miss some of the overall themes and some concepts are hard to demonstrate.
I have not seen evolutionary concepts in the book. It and others in the series seem best for about grades 3 through 5. Younger kids could profit from most of the activities. The explanations don't bring out the scientific principles clearly enough for older ones.
Part of a series from John Wiley & Sons.

I suppose that a child with little natural curiosity would find this book interesting. But if you are trying to introduce new concepts to your children there are better bets.

However, this is about all the book is good for. The explanations of various phenomena are extremely limited, VanCleave provides none of the legends behind the constellations, and her suggested questions and activities are often impractical or pointless. (She also turned Saggitarius into some unholy thing she dubbed 'The Teapot.' Sheesh.) The book wavers between being a teacher's handbook and a student's textbook -- and fills neither purpose very well.
In other words, don't buy it. Skim through it and take any useful activities and explanations, but don't be too disappointed if you come away with only a few ideas.
