As he begins to discover the interesting rocks all around him, Spenser has many questions about what he finds. Given the differences in the rocks’ colours, sizes, shapes, and textures, there is much to learn about rocks! But that’s not all the curious child learns in this tale of discovery. Spenser’s fascination grows as he sorts and re-sorts his rock collection and asks questions about what he observes. For Spenser—as well as young readers—the experience is an engaging introduction to scientific procedures such as classification and research.

Spenser and the Rocks is part of the I Wonder Why book series, written to ignite the curiosity of children in grades K–6 while encouraging them to become avid readers. These books explore the marvels of geology, land forms, weather, environments, and other phenomena related to science and nature. Included in each volume is a Parent/Teacher Handbook with coordinating activities. The I Wonder Why series is written by an award-winning science educator and published by NSTA Kids, a division of NSTA Press.
