Science is all about answering questions, and this series looks at ongoing investigations. Each book introduces read- ers to its theme and includes a reminder of the scientific method. The text then covers what scientists have already learned as well as current explorations. Captioned images and text boxes add even more information about plate tectonics, black holes, or the panspermia theory. Sidebars take readers to hydrothermal vents and on the search for a Goldilocks planet. Back matter in- cludes a glossary and suggested books and websites for more exploration. VERDICT A great way to add current inquiry topics to your collection and perfect for students who never run out of questions.
