Abstract
This booklet has developed from two main sources. One is Life Science 101 taught at Sacramento State College; the other is my personal experience as the mother of a son, as a den mother of a cub scout group, and as a teacher in elementary schools in Canada, Scotland, and California. The life science course formed a foundation for gathering material, a much-needed help. The experiences of my life showed me the need for matter that is of interest and value to growing children, matter which might serve to promote belief in conservation, and in the enjoyment of the earth and the fullness thereof.
