Designed to present interesting facts about science and to heighten the curiosity of primary age students, this book contains activities about the natural world and numerous black and white illustrations. The activities focus on familiar animals that are found in the air, on land, and in the water. A duckling named Little Mac Mallard introduces the learning games, fill-ins, songs, and experiments which center on animal characteristics and behaviors. Directives for the individual activities are provided in the teacher/parent guide section and include: (1) discussion questions; (2) explanations of the learning activities with an answer key; (3) vocabulary list; and in most cases (4) extended activities.
