The content and vocabulary were good for my age group, but I didn't learn very much, nor did I learn anything interesting. That's from my point of view. It had a bunch of cool illustrations and they helped a lot. I would read it again if I had a report to do, and I would recommend it to a friend. Illustrations by Pat Stephens.

For my age group, it could have had harder words and still been understood. I was a little disappointed because I already knew a lot of the facts in the book. One thing I did learn was that a butterfly tastes things 200 times better than humans do. The organization and the ideas were clear, one thing led to another. The book had an illustration on every page, which made it easier to understand.
