School Library Journal Reviews 2010 November

K-Gr 3--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.
