Reseñas de la Crítica

"This series is well organized and written in clear, concise language. The first chapter in each volume focuses on why a particular form of energy is important for people and/or the environment. Successive chapters discuss how that energy is generated and how it can (or cannot) be manipulated to people's advantage. Simple experiments using everyday household objects with clear instructions are provided in almost every chapter, with appropriate notes when adult supervision is necessary. Crisp photographs and/or diagrams are presented on every page, as are side boxes that contain either additional information or ask questions that draw readers back into the main text." (School Library Journal, Series Made Simple)

"These books start with definitions of force, work, and machines, then explain how machines reduce the amount of force needed to do work. Interactivity is encouraged, as readers are directed to perform simple experiments along with children shown in accompanying pictures; the texts provide guidance on what to look for. Clear explanations, relatable examples, and effective visuals make these solid selections." (The Horn Book Guide)

"This series, written by well-known author Sally M. Walker, is most suitable for middle to late elementary grades. Each paragraph sums up an idea with a picture to reinforce it. The books also make use of interesting science experiences which will draw the attention of readers. The use of everyday examples makes these scientific facts more easily comprehended. There are also caption boxes that add a bit more information to each topic. The 'Learn More About' page in each book makes them more accessible to readers who may want to know more about a certain concept. The series is a great beginning science unit for middle aged learners." (Library Media Connection)

"Investigating Sound (part of the How Does Energy Work? series) would be a great addition to a science unit focusing on sound. The book's cover makes you want to open it to see if there are more wonderful photos inside. Photos of children conducting sound experiments are found throughout the book, and these are accompanied by simple text to explain what is happening and why. Bright yellow text boxes are placed in key areas to draw a child's attention to neat factoids. The experiments, which are low cost and require minimal time, would enrich a lesson because they are visual and hands-on. Various nonfiction features are included to enhance learning; these include a table of contents, a glossary, a 'Learn More' section, and an index. Sally Walker, the author of the entire series, has been a children's author for 20 years in the field of nonfiction science books. The series would be a beneficial addition to any classroom science library or teacher resource room." (NSTA)
