At the Art and History museum, an exhibit is opening-an exhibit about people!People fascinate young dinosaurs. They have people t-shirts, toys, and posters on their walls. They're thrilled to know more about this extinct species, so they head to the museum with great enthusiasm. There, they learn all about humanity and discuss extinction and what little dinosaurs can do to avoid a similar fate. Told in verse, Mr. Triceratops' Class teaches an important lesson but is also told in a delightful and uplifting manner for both child and parent alike.
