Explores fossils from how and where they form to how scientists gather and preserve them. Includes a glossary, resources for further information, diagrams, and color photographs.

Text, photographs, and diagrams describe the scientific processes that turn sand into glass, and explain how mirrors reflect images.

Explains the water cycle, focusing the scientific process by which water is used to create energy.
