Pluto’s Secret: An Icy World’s Tale of Discovery, by Margaret A. Weitekamp and David DeVorkin ISBN 9781419704239
Five out of five stars
This is a gem of a science book for children. Written at the level of the early elementary school student, it tells the basic tale of the discovery of Pluto, why it was first considered a planet and then why it was demoted. The most interesting point is that the demotion was a consequence of an emerging scientific consensus as to the definition of a planet. It is amazing to learn that it was not until 2006 that a convention of astronomers met and concluded that Pluto was not a planet.
If you are looking for a book that combines science education with the cuteness of imagery and dialog that attracts the young reader, this is one that parents and children will enjoy.
