Tuba City -- bewteen Flagstaff and Monument Valley -- is one of the main towns in the Navajo Nation Reservation; the museum here is a good introduction to Navajo history and culture.
Exhibits include a hogan (traditional dwelling) that visitors can walk inside; a section on Navajo sheep's wool and dyeing and weaving; sandpainting, pottery, and more. Older kids might learn about the most prominent tragedy in Navajo history: The Long Walk forced move of 8500 men, women, and children in the winter of 1863.
Across the plaza from the Museum is an exhibit about the Navajo Codetalkers: during World War II, some 420 Navajo men communicated secret messages in the Navajo language, as part of the US Marines' operations in the Pacific.
