Dinosaurs have great educational potential because they fascinate young minds and the general public. The ancient Chinese, Greeks and Romans explained their fossils with beautiful legends; in the Twentieth century, Jurassic Park and Walking with Dinosaurs brought dinosaur science to the masses. Here I explain how to make three inexpensive and simple activities: the first one teaches how to reconstruct the appearance of a dinosaur and its habitat from fossils and focuses on the requirements of the Scientific Method; it can be done with a computer or manually. The second is a simple drawing practice that teaches the impossibility of faithfully copying an extinct species (despite the current proposals for species “de-extinction”). The third activity is a dramatization about ethical conflicts related to fossils. The article includes activity cut-outs and detailed steps, how to evaluate and practical advice
