Noting the increase in interactive museums and science centers and children's exuberant reaction to hands-on exhibits, this guide provides tips for parents on how to prepare for a museum visit and how to encourage the learning process during the visit. The first part of the guide discusses the shift in museum policy from "hands off" to "please touch," and how this interactive format enhances children's learning processes. The second part of the guide contains museum listings, by state. Each listing includes detailed discussion of what the museum offers; age-appropriate guidelines to exhibits; information on available workshops, infant-toddler play spaces, planetariums; and information on nearby child-appropriate attractions such as zoos, parks, restaurants, and picnic areas.
