Get kids reading with lots of cool information about subjects that matter to them! The “National Geographic Readers” series does this with simple, fun text, colorful photos and kid-friendly diagrams. Each book falls into one of five reading levels. Anne Schreiber's narrative gives readers a little science, a little history, and a lot of action of volcanoes. National Geographic photography fires the imagination on dramatic spreads alive with vivid images of lava, ash, molten rock, weird rocks, and steaming seawater.
