Join Mr. Tiffin and his students on a trip to a natural history museum and learn all about dinosaurs and the scientists who discovered them! Mr. Tiffin and his students are back in another picture book, and this time the focus is on dinosaur-loving Kimmy. During a field trip to the natural history museum, Kimmy is thrilled to share what she knows about the Stegosaurus and the Archaeopteryx and even the ginormous Titanosaurus. That changes when one of her classmates questions whether girls can be paleontologists. Kimmy starts to feel shy. What if they can't? What if no one wants to hear what she has to say? It will take some help from Mr. Tiffin—and from a famous scientist—for Kimmy to find her voice again. Join Mr. Tiffin's class as they learn about dinosaurs big and small, feathered and scaly, winged and ocean-dwelling. And root for Kimmy, the dinosaur expert . . . who might just learn something about herself.
