Visitors don’t have to be kids to be fascinated by the National Air and Space Museum. Part of the Smithsonian Institution, the National Air and Space Museum offers plenty of hands-on activities for kids of all ages, from eight to 80. The museum is a treasure trove about America’s air and space programs. Exhibits include everything from the 1903 Wright Flyer to the Apollo 11 moon-landing expedition to exhibits on how scientists are exploring space today. The best part? Admission to the basic museum is free, though fees charged may be charged for features such as IMAX.
