"These voumes are kid friendly and are intended to introduce elementary and middle-school-aged children to scientific inventions and concepts. These titles will be useful in school media centers and children's reference collections in public libraries."
"This series explores the concepts of the title of each volume by defining and explaining what they are and how they work. Colored photos on nearly every page make the series visually attractive while they add to the understanding of the text. Appealing illustrations and text will interest young readers with information suitable for reports. Recommended."
