Science has grown through the experimentation and speculation of many men who from the dawn of history have searched sky and earth for the truth about the universe. They are the explorers in each of these attractive books ["Exploring the Planets," "Exploring the Sun," and "Exploring Chemistry"] which will appeal particularly to young people who have some knowledge of the subjects treated, and who are asking, "How were these discoveries made?"

In "Exploring the Planets," young astronomers will find essential facts about the members of the sun's family, and much more…. What is known is carefully distinguished by the author from what is speculative.

Somewhat more specialized is "Exploring the Sun."… There is a dramatic final section on "the day the sun goes out."

"Exploring Chemistry" tells how that science had its beginnings…. Fundamental principles of modern chemistry are then developed through the work of scientists such as Priestley, Lavoisier and Dalton.

These books, which provide both information and inspiration, merit a place on the teenager shelf.
