Natural history museums are especially interesting to most kids as they are home to dinosaur fossils--and the Museum Kids are no exception! As they explore the museum, they happen upon a magical elevator that takes them back in time and around the world! Readers travel with the Museum Kids to see Earth's first life-forms, woolly mammoths, and even dinosaurs in their habitat. Beautiful illustrations complement the at-level text and show the danger, adventure, and fun had by the Museum Kids in this engaging volume. A concluding quiz allows readers to test what they have read.
