(47) Some of the old, gray museums have been rebuilt, and the newer ones are open and modern in their architecture. Inside, there is modern lighting, color, and sound. Instead of displaying everything they own, museum directors show fewer objects and leave open spaces where visitors can gather and sit down. They also bring together in one display a group of objects drawn from various parts of the museum in an effort to represent the whole lifestyle of a region or a historical period. (48) . More and more, museum directors are realizing that people learn best when they can somehow become part of what they are seeing. In many science museums, for example, there are no guided tours. The visitor is encouraged to touch, listen, operate, and experiment so as to discover scientific principles for himself. He can have the experence of operating a spaceship or a computer. He can experiment with glass-blowing and paper-making. (49) The theory is that people who do not understand science will probably fear it, and those who fear science will not use it to best advantage. Many museums now provide educational services and children’s departments. In addition to the usual displays, they also offer film showings and dance programs. (50) . A The purpose is not only to provide fun but also to help people feel at home in the world of science. B Museums have changed. C In one room, for instance, you may find materials, clothing, tools, cooking pots, furniture, and art works of a particular place and time. D Instead of being places that one "should" visit, they are places to enjoy. E There are open spaces that museums leave for visitors. F Many museums have changed in appearance.
