This is one of my textbooks for my classes this year. For $73, one would expect to find color pictures, well written text, and current information, however, this book lacks all of these. Published in 1990, the info is at least ten years old. I can't believe they charge this much for a book. It is not Amazon's fault, it is the publisher.

This book has been around quite a few years, but the authors have updated each edition for new trends, especially in space exploration, technology, and the constructivist orientation to science teaching. I am using it for an Integrated Physical and Biological science content class for elementary teachers. I can supplement with web searches for jazzy pictures, or low information density lessons, but for a good all round knowledge reference, with the extra of alternating chapters to emphasize methods of teaching elementary science, I haven't found a better physical/biological science text.
