K-Gr 1-Simple texts complemented by dialogue-bubble commentary and bright, cartoon illustrations introduce science concepts. In the first title, when an acorn falls on a squirrel, he watches and learns how the life cycle of an oak tree begins. The book outlines the steps from seed to oak tree and ends with a diagram of the tree's life cycle. In Paint, a group of friends explore their neighborhood and play throughout a year. Their clothing and activities change according to the season. Simple facts are related such as in the summer there is plenty of fresh fruit and "in winter, the sun is low in the sky." This book concludes with a scientific explanation of why there are seasons. In Rainbow a grandfather and his granddaughter take a walk after it rains. The book provides very basic commentary on such topics as nature's colors and how colors can be mixed. Directions for making a spinning color wheel are included. While the story lines may interest children, they are slight, as is the information.-Sandra Welzenbach, Villarreal Elementary School, San Antonio, TX Copyright 2005 Reed Business Information.
