Life Cycles

Discusses the life cycle of humans and other mammals, plants, insects, frogs, reptiles, and birds. The concept of fertilization is not mentioned and the sexes are only alluded to once where a cat that had kittens was noted to be a she. In the discussion of reptiles, it seems all snakes can lay eggs based on this sentence. "When a reptile such as a snake is fully grown, it can also lay eggs." That seems a little too vague. The text asks the reader simple questions and provides answers at the back of the book. Life Cycles includes a simple glossary, bibliography, and index. Other entries in this series rate five stars, such as "Plants" and "Changing Forms." Karen Woodworth-Roman, Children's Science Book Review
