Students explore prehistoric life by simulating the way real scientists learn about dinosaurs by examining their fossils and their footprints. After spanning the millennia with a geological time line, students create, bury, and unearth imitation fossils, the backbone of dinosaur research. They try to reconstruct dinosaur skeleton models and speculate about the animals’ appearance and behavior, based on their bones. They investigate dinosaur footprints and make inferences about size, speed, and stride. Using dinosaur models, students become familiar with various dinosaurs’ physical features. They develop a classification system and learn the meanings of dinosaur names.
