K-Gr 3—This solid series is a commendable approach to weather studies, meeting early elementary standards for science education. The pleasing photos (illustrating the smallest water droplet to the largest puffy white cloud) and colorful format will hold readers' interest. The descriptive narrations are punctuated with text boxes and interactive questions that prompt students to hypothesize, assimilate facts, observe, conclude, and experiment. Each installment encourages scientific inquiry in a fun way and includes a "Science Lab" activity. On rare occasions, word definitions are vague, e.g., "gas" is defined in the glossary as "a form of matter that spreads out to fill all the space of whatever it is in." But in sum, this series is credible and creative.
