From the Publisher
"Award-winning author Sally M. Walker has written a beautifully crafted earth science series for young readers. Organized by answering a series of questions, each book has suggestions for further learning if you 'dig' earth science. The graphics are visually helpful to discern topics, captions, and important points in a readable font. Composed in a clear, progressively building logic, every science word is simply defined. Pictures, charts, and diagrams reinforce learning and suggest student experiments. Informational text that is widely accessible to children is a must in every library, and this series fits the bill." —starred, Library Media Connection
