Rock It!: Sets 1 - 2

Although the rocks beneath us seem very strong and stable, they are constantly undergoing changes such as weathering, eroding, and breaking apart during earthquakes. This compelling and useful collection is designed to complement lower elementary science curricula. The books explore Earth Science topics that kids can observe in the world around them, such as erosion and soil. Sidebars offer extra information and each book has its own web site with links related to the topic of the book.
