Hands-on science centers are one of America's newest and most popular types of museums. Beginning with a history of the science center movement in the United States, this book then presents detailed entries on more than 260 museums and sites where the visiting public can touch, handle, and interact with exhibits or objects in entertaining and educational ways. Each entry includes a description of the center's hands-on exhibits, programs, and events, along with contact information, hours, and ticket information. The book contains 75 photographs of the exhibits in action.
