An Egg is Quiet is a very appealing, informative book with exceptional illustrations, accurate content, evidence of research, well organized content, and appropriate typeface.
Sylvia Long's illustrations are wonderful, realistic, and eye-catching. "An egg is ______" is introduced at several points in the book, emphasizing the many characteristics of eggs, such as sizes, shapes, textures. e.g. "An egg is colorful."
At the front of the book there is a double-spread of labeled eggs and at the back of the book there is a double-spread of labeled birds, insects, and egg-hatching creatures that can be matched up to the eggs. The endpapers are even blue and speckled like eggs!
Dianna Aston and Sylvia Long have teamed up on other picture books that are similar to An Egg is Quiet: A Rock is Lively, A Butterfly is Patient, and A Seed is Sleepy. I recommend the book Eggs by Marilyn Singer for children seeking more information on eggs than they can find in An Egg is Quiet.
