Children's museums are institutions that provide exhibits and programs to stimulate informal learning experiences for children. In contrast with traditional museums that typically have a hands-off policy regarding exhibits, children's museums feature interactive exhibits that are designed to be manipulated by children. The theory behind such exhibits is that activity can be as educational as instruction, especially in early childhood. Most children's museums are nonprofit organizations, and many are run by volunteers or by very small professional staffs.

A museum is an institution dedicated to displaying and/or preserving culturally significant objects. Many museums have exhibitions of these objects on public display, and some have private collections that are used by researchers and specialists. Compared to a library, a museum hosts a much wider range of objects and usually focus around a specific theme such as the arts, science, natural history, local history, and other topics. Public museums that host exhibitions and interactive demonstrations are often considered to be tourist attractions, and many museums attract large numbers of visitors from outside their host country, with the most visited museums in the world regularly attracting millions of visitors annually.
