Gr 2-4 These dual-purpose introductions to nature and to graphic texts include a how-to-read-panels diagram on their back covers. Information is presented in text boxes, word balloons, and labeled diagrams. Panels vary from vertical to horizontal; they occasionally fill full pages but are typically presented three per page.

Minor quibbles include a confusing explanation of ground and surface water in Water and an unlabeled diagram of the osmosis process in Seed .
