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. Activities that focus on the dinosaur are organized into five sections. These include: (1) "Dinosaur Facts/Then and Now" (exploring bird and reptile characteristics); (2) "Dinosaur Eggs/Facts and Fun" (containing experiments, a song, and an art activity); (3) "The Dinosaur Dentist" (examining the two major classes of dinosaurs by their teeth); (4) "Prehistoric Plant Detective" (including activities that help students to discover dinosaur food in the form of plants and trees that exist today); and (5) "Final Features" (providing a pattern and instructions for a dinosaur puppet). The teacher/parent guide section contains directives for assembling a dinosaur egg-puppet carrying case and also identifies sources for additional dinosaur activities. (ML)
