Book excerpt: Dinosaurs are every students fascination. Reproducible, hands-on activities give students the opportunity to experience how the scientific process works and how scientists form and test conclusions. Students build and employ skills in analysis, drawing, measuring, graphing, and arithmetic; exercise research and library skills to acquire data necessary to complete the activities; and apply critical-thinking skills to extrapolate from the known to the unknown-the fundamental process that makes science work. Grades 4-12.
