Gr 2-4–What makes this series different is the inclusion of Common Sense, a book that presents that attribute as the result of experiences gained through other senses, and contrasts it with instinct. Another unusual feature is the addition of umami, a meaty or savory flavor, in Taste. Otherwise, the content is standard fare. The striking color photographs are often extraneous and lack labels, and there are no diagrams. Scientific vocabulary is avoided unnecessarily or added without adequate explanation. An uninspired hands-on activity at the end of each book varies from extremely simple to beyond the age level of the intended audience.
