What Floats? What Sinks?: A Look at Density (Lightning Bolt Books) - Softcover

"Filled with large, engaging photos, each book is divided into subtopics that contain definitions, explanations, and several examples of the physical science principle. The end of each volume includes directions for completing an activity that illustrates the concept and prompts further thinking. Though content is slight, these books could serve as adequate introductions to their respective subjects." --The Horn Book Guide

"Jellybean-bright backgrounds, large photographs, and brief texts will draw readers to this series. The use of questions and image choices help to make the topics relevant and interesting. Scientific terminology is accurate and understandable although at times the examples, such as 'Stepping on the gas makes a car give off pollution, ' are over-simplified. Occasional photos miss the mark. Attract and Repel implies that coins are magnetic. Captions closely follow the text, missing opportunities to extend content. The concluding activity is simple and clear, but the suggested websites are often too advanced for the audience." --School Library Journal, Series Made Simple

"With simplistic text accompanied by vivid photographs, each title explains an area of physical science, such as force, motion, and density. Using real life examples, the author explains the topic in a meaningful way for young readers. Each title is organized into five sections, followed by a hands-on activity that demonstrates the book's subject. This series would be a welcome addition to school libraries' science section as well as elementary science classrooms. Recommended." --Library Media Connection
